A typical septic system consists of a septic tank and a drainfield, or soil absorption field. The septic tank digests organic matter and separates floatable matter (e.g., oils and grease) and solids from the wastewater.

Can you have a septic tank without a leach field?

The waste from most septic tanks flows to a soakaway system or a drainage field. If your septic tank doesn’t have a drainage field or soakaway system, the waste water will instead flow through a sealed pipe and empty straight into a ditch or a local water course.

What does a distribution box do in a septic system?

The distribution box lies between the septic tank and the drainfield, and serves to evenly distribute the wastewater evenly amongst the drainfield lines.

What is leaching chamber?

A leaching chamber is a wastewater treatment system consisting of trenches or beds, together with one or more distribution pipes or open-bottomed plastic chambers, installed in appropriate soils. A small portion of the effluent is used by plants through their roots or evaporates from the soil.

What is a septic tank baffle?

Septic baffles are located at the junctions where pipes enter and exit the tank. The one at the inlet pipe is called the inlet baffle, and the one at the outlet is called the outlet baffle. It’s designed to help wastewater flow smoothly into the tank without disturbing the scum layer.

What is an Aerobic Septic System?

It is also referred to as anaerobic treatment system (ATS), and it is a minor wastewater treatment approach that employs an aerobic way to digest sewages. Anaerobic septic systems function in the same way as aerobic septic systems, with the exception that the aerobic septic system employs an aerobic technique rather than an anaerobic procedure. These systems are especially frequent in rural locations where municipal sewers are not readily available. This means that they may be used for either a single-family home or a small group of dwellings.

This allows you greater freedom in determining the placement of the leach site and reduces the size of the leach site to half its original size.

The additional oxygen boosts the natural bacterial activity in the system, allowing for even more nutrient digestion in the sewage as a result.

Residences with poor soil conditions and narrow parts, places with a very high water table, and houses near surface water are all candidates for this system, which has the benefit of being less susceptible to pollution from nutrients contained in sewage.

How does an Aerobic Septic System work?

An aerobic treatment system is a sewage treatment system that employs mechanical components to treat sewage and release the treated sewage into an absorption region after treatment. It makes use of aerobic microorganisms, which require a constant supply of fresh air to live. Organic waste that passes through the septic system is processed by these aerobic bacteria, which are so termed because they utilise oxygen (the “aero” part of the word “aerobic”). Without organic materials and oxygen, these bacteria are unable to reproduce and carry out their therapy functions.

A puddle or some mud is where bacteria can be found living in the aerobic septic system.

Bacteria consume sewage products, breathe the air, and excrete CO2 as waste products into the environment. Aerobic treatment, often known as aerobic septic system, is comprised of the procedures listed below, which work together to provide high-quality wastewater. Process:

  • Prior to treatment, the septic tank is put in front of the ATU (Aerobic Treatment Unit), or the ATI-J can incorporate a septic or waste tank as part of its equipment. As part of the pre-treatment process, the sediments are separated from the sewage water. Blower or air compressor pumps the air into the wastewater in the aeration chamber during this stage. Aeration Chamber: As a result of this process, the development of aerobic bacteria, which aid in the digestion of solids in the effluent, is stimulated. Disinfection: This stage includes an additional treatment step for wastewater that has exited the aerobic treatment unit (ATI-J) or the ATI. You can use UV light or chlorine to complete this process. Before the wastewater is discharged into the pump tank, it is further treated with ultraviolet radiation, bleach, chlorine, or other disinfection methods. Finally, ATI-J wastewater is released into a drainage region, which may be an evapotranspiration bed, an absorption area, or a sand filter.

3) Add chlorine to your tank

Providing you know the dosage and frequency recommended in the instruction booklet that came with your aerobic septic unit, this step should be rather straightforward. Keep in mind that pool chlorine does not sanitize the sewage, so exercise caution while using it.

However, it will kill all of your plants and grass. Remove the lids from the aerobic treatment system and replace them with the recommended amount of septic-friendly chlorine. Replace the lids in their original position and screw them back on.

4) Keep an eye on the spray fields

Providing you know the dosage and frequency specified in the instruction booklet that came with your aerobic septic unit, this step should be rather straightforward. Avoid using pool chlorine if you want to keep the sewage from becoming contaminated. In the process, though, your plants and grass are destroyed. Using a screwdriver, carefully remove the lids from the aerobic treatment system, then pour the recommended amount of septic-friendly chlorine before replacing the lid.

5) Keep a maintenance record

If you know the name of the model, the year of installation, the status of your license, and the capacity of your aerobic treatment unit, you can more easily identify the sort of system you have and the circumstances under which it is maintained. The ability to maintain track of which parts of your system have been fixed and when can aid you in keeping track of which tests and services are currently running on your system. Depending on factors such as how often chlorine should be added, the results of clarity tests and residual free chlorine tests, as well as the kind and date of repair, it may be determined exactly when the garbage tank should be removed and an aerobic treatment unit should be pumped.

During this maintenance, the following items will be performed:

  1. Fill up a spreadsheet with the quantity of free chlorine residue found in wastewater from the pumping station. Measure the depth of the slurry in the garbage tank and make a note of it. ATU measures and records the amount of sludge present. Perform a clarity test and note the results (Pass or Fail)
  2. A

FAQ Section

The anaerobic septic tank system is made up of two parts: a seepage field and a treatment tank (or treatment chamber). Solid debris and slag are deposited at the bottom of the treatment tank, with the wastewater settling in the middle. The wastewater is then pumped out through a pipe into a holding tank. The effluent is largely free of contaminants. As a result, it passes via a system of pipes that are concealed beneath the leach area. Several systems use a divider box between the pipe and the tank in order to provide more constant effluent delivery.

  • The aerator in the aerobic septic system continually feeds oxygen to the bacteria in the tank while the system is in operation.
  • A moving pallet, as previously indicated, helps to prevent the effluent from separating into three distinct levels as it passes through the system.
  • The wastewater from the leach site becomes cleaner and simpler to treat as a result of this mechanism.
  • Septic systems that are anaerobic in nature are less expensive than aerobic septic systems.

Although an aerobic septic system is beneficial to the environment, it is more expensive to acquire and operate than a standard septic system. It also requires more upkeep, however anerobic bacteria are less active than aerobic bacteria when compared to the latter.

Can I put a aerobic septic tablet in my toilet tanks?

In the case of anaerobic septic tanks, the system is comprised of a seepage field and a treatment tank, respectively. Solid garbage and slag are deposited at the bottom of the treatment tank, with the wastewater settling in the middle. The wastewater is then pumped out through a pipe to a treatment plant. The wastewater is generally considered to be of high quality, although not perfect. Consequently, it passes via a system of pipelines concealed beneath the leach region before reaching the treatment facility.

  • At the leaching stage, the final filtration process before the treated effluent is released back into the environment is completed.
  • The steady supply of oxygen keeps the bacteria more active and speeds up the treatment process.
  • Aerobic bacteria are able to detect even solid trash that has accumulated at the bottom of an anaerobic system.
  • A more effective system than an anaerobic septic system, an aerobic septic system requires a more complicated installation process.
  • In addition to the storage tank and leach site, homeowners must purchase an aeration system.
  • However, anerobic bacteria are less active as compared to aerobic bacteria, which means it requires more upkeep.

Can a root killer be used in an aerobic septic system?

  • Gravity or traditional septic systems, as well as the utilization of a uniform distribution system in conjunction with drain field technology to obtain a type 2 system, can cost between $20,000 and $30,000 to construct. In order to attain a type 2, an ATU septic system installation can cost anywhere between $25,000 and $35,000
  • However, this is not always the case. Depending on the geography, the cost of using an ATU in conjunction with a subsurface drip line might range from $25,000 to $35,000. The cost of using an ATU in conjunction with an Evotranspiration bed is between $25,000 and $40,000, depending on the home’s size.

In the case of a Type 3 septic system, which requires an additional disinfection unit in addition to the aeration unit, we may estimate an additional cost of $10,000 to $15,000 beyond the previously examined cost points. More information on determining the cost of a septic system may be found here: Design Services for a Septic Design are typically $2000 for Type 1 Gravity systems and $2500 for Type 2 Gravity systems and Pressure systems, depending on the system.

A Type 3 septic system, which requires an additional disinfection unit in addition to the aeration unit, may be designed for an estimated cost of $10,000 to $15,000 higher than the previously examined cost points when designed by an engineer. The following information will provide you with further insight into how the cost of a septic system is determined: Design Services for a Septic System are typically $2000 for Type 1 Gravity systems and $2500 for Type 2 Gravity systems and Pressure systems, respectively.

Types of Septic Systems

Septic system design and size can differ significantly from one neighborhood to the next, as well as throughout the country, due to a variety of variables. Household size, soil type, slope of the site, lot size, closeness to sensitive water bodies, weather conditions, and even municipal ordinances are all considerations to take into consideration. The following are 10 of the most often encountered septic system configurations. It should be noted that this is not an exhaustive list; there are several additional types of septic systems.

  • Septic Tank, Conventional System, Chamber System, Drip Distribution System, Aerobic Treatment Unit, Mound Systems, Recirculating Sand Filter System, Evapotranspiration System, Constructed Wetland System, Cluster / Community System, etc.

Septic Tank

This tank is underground and waterproof, and it was designed and built specifically for receiving and partially treating raw home sanitary wastewater. Generally speaking, heavy materials settle at or near the bottom of the tank, whereas greases and lighter solids float to the surface. The sediments are retained in the tank, while the wastewater is sent to the drainfield for further treatment and dispersion once it has been treated.

Conventional System

Septic tanks and trench or bed subsurface wastewater infiltration systems are two types of decentralized wastewater treatment systems (drainfield). When it comes to single-family homes and small businesses, a traditional septic system is the most common type of system. For decades, people have used a gravel/stone drainfield as a method of water drainage. The term is derived from the process of constructing the drainfield. A short underground trench made of stone or gravel collects wastewater from the septic tank in this configuration, which is commonly used.

Effluent filters through the stone and is further cleaned by microorganisms once it reaches the soil below the gravel/stone trench, which is located below the trench.

In terms of total footprint, gravel and stone systems are very substantial, and therefore may not be appropriate for all residential sites or situations.

Chamber System

Gravelless drainfields have been regularly utilized in various states for more than 30 years and have evolved into a standard technology that has mostly replaced gravel systems. Various configurations are possible, including open-bottom chambers, pipe that has been clothed, and synthetic materials such as expanded polystyrene media. Gravelless systems can be constructed entirely of recycled materials, resulting in considerable reductions in carbon dioxide emissions during their lifetime. The chamber system is a type of gravelless system that can be used as an example.

  • The key advantage of the chamber system is the enhanced simplicity with which it can be delivered and built.
  • This sort of system is made up of a number of chambers that are connected to one another.
  • Wastewater is transported from the septic tank to the chambers through pipes.
  • The wastewater is treated by microbes that live on or near the soil.

Drip Distribution System

An effluent dispersal system such as the drip distribution system may be employed in a variety of drainfield configurations and is very versatile. In comparison to other distribution systems, the drip distribution system does not require a vast mound of dirt because the drip laterals are only placed into the top 6 to 12 inches of soil. In addition to requiring a big dosage tank after the sewage treatment plant to handle scheduled dose delivery of wastewater to drip absorption areas, the drip distribution system has one major disadvantage: it is more expensive.

Aerobic Treatment Unit

Aerobic Treatment Units (ATUs) are small-scale wastewater treatment facilities that employ many of the same procedures as a municipal sewage plant. An aerobic system adds oxygen to the treatment tank using a pump. When there is an increase in oxygen in the system, there is an increase in natural bacterial activity, which then offers extra treatment for nutrients in the effluent. It is possible that certain aerobic systems may additionally include a pretreatment tank as well as a final treatment tank that will include disinfection in order to further lower pathogen levels.

ATUs should be maintained on a regular basis during their service life.

Mound Systems

Using mound systems in regions with short soil depth, high groundwater levels, or shallow bedrock might be a good alternative. A drainfield trench has been dug through the sand mound that was erected. The effluent from the septic tank runs into a pump chamber, where it is pumped to the mound in the amounts recommended. During its release to the trench, the effluent filters through the sand and is dispersed into the native soil, where it continues to be treated. However, while mound systems can be an effective solution for some soil conditions, they demand a significant amount of land and require regular care.

Recirculating Sand Filter System

Sand filter systems can be built either above or below ground, depending on the use. The effluent is discharged from the septic tank into a pump compartment. Afterwards, it is pushed into the sand filter. The sand filter is often made of PVC or a concrete box that is filled with a sand-like substance. The effluent is pushed through the pipes at the top of the filter under low pressure to the drain. As the effluent exits the pipelines, it is treated as it passes through the sand filtering system.

However, sand filters are more costly than a standard septic system because they provide a higher level of nutrient treatment and are thus better suited for areas with high water tables or that are adjacent to bodies of water.

Evapotranspiration System

Evaporative cooling systems feature drainfields that are one-of-a-kind. It is necessary to line the drainfield at the base of the evapotranspiration system with a waterproof material. Following the entry of the effluent into the drainfield, it evaporates into the atmosphere. At the same time, the sewage never filters into the soil and never enters groundwater, unlike other septic system designs. It is only in particular climatic circumstances that evapotranspiration systems are effective. The environment must be desert, with plenty of heat and sunshine, and no precipitation.

Constructed Wetland System

Construction of a manufactured wetland is intended to simulate the treatment processes that occur in natural wetland areas. Wastewater goes from the septic tank and into the wetland cell, where it is treated. Afterwards, the wastewater goes into the media, where it is cleaned by microorganisms, plants, and other media that eliminate pathogens and nutrients. Typically, a wetland cell is constructed with an impermeable liner, gravel and sand fill, and the necessary wetland plants, all of which must be capable of withstanding the constant saturation of the surrounding environment.

The operation of a wetland system can be accomplished by either gravity flow or pressure distribution. As wastewater travels through the wetland, it may escape the wetland and flow onto a drainfield, where it will undergo more wastewater treatment before being absorbed into the soil by bacteria.

Cluster / Community System

In certain cases, a decentralized wastewater treatment system is owned by a group of people and is responsible for collecting wastewater from two or more residences or buildings and transporting it to a treatment and dispersal system placed on a suitable location near the dwellings or buildings. Cluster systems are widespread in settings like rural subdivisions, where they may be found in large numbers.

Septic Tanks & Septic System Components

Anaerobic septic tanks are divided into three different levels as soon as the influent is introduced into one. Grease, oils, soap films, and any other items that are lighter than water can be found in the scum layer at the top of the septic tank’s surface layer. Both aerobic and anaerobic bacteria may be found in the scum layer; however, the anaerobic bacteria are the most prevalent. Septic tank scum is digested by bacteria at its surface, and as a result, the digested waste of the bacteria becomes heavier than water and descends to the bottom of the tank, where it is further cleaned.

In order for particles of any size and weight to discharge via the outlet baffle when the outlet baffle is correctly fitted, they must first pass through the clear zone as indicated above before passing through the outlet baffle.

Baffles in Septic Tanks

An effluent filter is installed within the output baffle to provide extra treatment. This can be a thin plastic mesh screen with slots or a bristle-style filter that looks similar to a giant bristle brush in appearance and function. Solids that are bigger than the open area of the filter are prevented from exiting the septic tank by the filter’s filtering action. It’s also possible that bacteria will develop on the surface of the filter bristles, further cleansing the effluent as it departs the tank and makes its way to the drainage field.

Another advantage of utilizing a filter is that it is more effective when there is a lot of liquid.

A filter would still allow the overflow to pass through and receive some treatment from the bacteria growing on its bristles before being discharged from the septic tank to a pumping chamber or drainfield.

While the intake baffle is intended to minimize surging during periods of high water demand in the home, heavy rains, or spring thaws, it also serves another role by preventing particles from accumulating on the scum layer.

Surging may cause the water level to rise over the outlet baffle dam in an instant, allowing particles to be released out of the septic tank chamber without being digested if there is no intake baffle installed.

Aerobic Septic System Parts & Supplies

When it comes to aerobic septic systems, the SEPTIC AIR PUMP or SEPTIC AERATOR is the most important component. The air pump or aerator on any aerobic septic system, regardless of brand, is a necessary component of the system. The air pump, also known as an aerator, is responsible for pushing air through a sequence of air lines and diffusers in order to form oxygen bubbles in wastewater. septic air pumps, as well as repair parts, rebuild kits, and components for all of these types of septic air pumps are available at Septic Solutions.

SUBMERSIBLE PUMP / IRRIGATION PUMP

Submersible effluent pumps are used if your Aerobic Septic System does not discharge its waste by gravity into a drainage ditch or into a subsurface leach field. This pump is commonly used in the southern portion of the United States to pump water to sprinklers in the yard or underground drip irrigation systems, for example. A High Head Effluent Pump is a type of submersible pump with a high pressure output that is used for effluent disposal. If you do not have irrigation, the most likely scenario is that you either have a normal effluent pump or no pump at all, depending on your situation.

AEROBIC SYSTEM CONTROL PANEL

Designed to operate and monitor the actions of the Aerobic Treatment System, the Aerobic System Control Panel is located in the Aerobic Treatment System. A failure of the air pump is frequently indicated by an alarm, as is a high water level indication by another alert. Depending on the model, some Aerobic Control Panels may also have a timer that regulates when the submersible pump or aerator may be used.

Aerobic treatment system – Wikipedia

It is also known as anaerobic septic system, and it is a small scale sewage treatment system that is similar to an aseptic tank system, but it uses anaerobicprocess for digestion rather than just the anaerobicprocess used in septic systems. It is also known as anaerobic septic system, and it is similar to an aseptic tank system. Typically found in rural places where municipal sewers are not available, these systems can be utilized for a single property or for a small group of residences, depending on their size.

This provides far greater flexibility in the positioning of the leach field, as well as the ability to reduce the needed size of the leach field by as much as half.

Process

According to common consensus, the ATS process consists of the following phases:

  • Large solids and other unwanted items are removed during the pre-treatment stage. It is at the aeration step that aerobic bacteria break down biological waste. The settling stage permits undigested materials to settle and become less noticeable. This results in the formation of sludge, which must be regularly removed from the system. During the disinfecting stage, chlorine or a similar disinfectant is added with the water, resulting in the production of an antiseptic output. Other options include using ultraviolet (UV) disinfection, which involves exposing the water to ultraviolet light within a UV disinfection equipment.

Optional disinfection can be performed if sterile effluent is desired, as in circumstances where effluent is dispersed above ground. A common disinfectant used in waste treatment systems is calcium hypochlorite tablets, which are specifically designed for use in waste treatment systems. The tablets are designed to degrade fast when exposed to sunshine. Plants in the leach field can be killed by stabilized forms of chlorine that remain in the environment after the effluent has been distributed.

Excessive concentrations of substances such as bleachorantibiotics can harm the ATS environment and impair the efficacy of the treatment process. Nondigestible substances should also be avoided since they will accumulate in the system and necessitate more frequent sludge cleanup.

Types of aerobic treatment systems

Aerobic systems for small-scale applications are often divided into two types: fixed-film systems and continuous flow, suspended growth aerobic systems (CFSGAS). The pre-treatment and effluent handling are the same for both types of systems, with the only variation being the aeration stage in the second type.

Fixed film systems

Fixed film systems make use of a porous media that serves as a substrate for the biomass film that digests the waste material in the wastewater and removes it from the system. Designs for fixed film systems are diverse, but they may be divided into two broad groups (though some systems may combine both methods). Both systems use stationary media and variable wastewater flow to alternately immerse and expose film to air. The first system uses media that is moved relative to the wastewater, and the second system uses a stationary media and varies wastewater flow so that the film is alternately immersed and exposed to air.

Alternatively, any appropriate porous material, such as molded plastic or peat moss, can be used to create the film.

A typical moving media method is the rotating biological contactor (RBC), which employs disks that rotate slowly on a horizontal shaft to move the media between two points in space.

Continuous flow, suspended growth aerobic systems

Because they are intended to handle continuous flow, continuous flow CFSGAS systems do not offer a bed for bacterial film growth, instead depending on bacteria floating in the wastewater to conduct their job effectively. Suspension and aeration are commonly provided by an air pump, which pushes air through the aeration chamber, ensuring that the wastewater is constantly stirred, in addition to providing oxygenation. Some systems that are intended to handle greater than typical quantities of biomass in the wastewater may require the addition of a medium that promotes fixed film bacterial growth.

Retrofit or portable aerobic systems

The repair of failing or failed anaerobic septic systems, which may be accomplished by retrofitting an existing system with an aerobic element, is another increasingly prevalent application of aerobic treatment. It is intended to rehabilitate biologically failed and failing anaerobic distribution systems by lowering the biochemical oxygen demand (BOD5) and total suspended solids (TSS) in the effluent by a substantial amount. The decrease of BOD5 and TSS has the effect of reversing the development of the bio-mat.

Composting toilets

In contrast to the above types of aerobic treatment systems, composting toilets are designed to treat only toilet waste, rather than general residential waste water. They are typically used in conjunction with water-free toilets rather than the flush toilets associated with the above types of aerobic treatment systems. They treat waste as a moist solid rather than a liquid suspension, and they separate urine from feces during treatment in order to maintain the proper moisture content in the system during the treatment process.

It consists of an inclined chamber that separates urine and feces, as well as a fan to provide positive ventilation and prevent odors from escaping through the toilet.

Treatment times are extremely long, with a minimum time between solid waste removals of one year; during treatment, the volume of solid waste is reduced by 90 percent, with the majority of it being converted into water vapor and carbon dioxide.

Pathogens are eliminated from waste by exposing it to inhospitable conditions for extended periods of time in the treatment chamber.

Comparison to traditional septic systems

The key distinctions between an aerobic treatment system and a standard septic system are the aeration stage and the disinfection step; in fact, an aerobic treatment system may be utilized as a secondary treatment for septic tank effluent. Because of these steps, the aerobic system has a higher starting cost and also has higher maintenance requirements in comparison to a passive septic system. The air pump in aerobic treatment systems requires a continual supply of energy, which increases the overall cost of the system, in contrast to many other types of biofilter.

As a positive side effect, because an aerobic system produces higher-quality effluent than a conventional septic tank, the leach field can be smaller than that of a conventional septic system.

The effluent from certain aerobic systems is recycled through a sprinkler system, which may then be used to irrigate the grass where the local ordinances permit this.

Effluent quality

Because the effluent from an ATS is frequently dumped onto the surface of the leach field, the quality of the effluent is extremely critical to maintain. When operated properly, a typical ATS will create effluent containing fewer than 30 mg/liter BOD5, 25 mg/L TSS, and 10,000 cfu/mL fecal coliform bacteria, among other parameters. A biomat or “slime” layer, such as that seen in a septic tank, cannot be supported by this environment. The effluent from an ATS system is largely odorless; a well working system will create wastewater that smells musty, but not sewage-like.
