Hence, your aerobic septic system is made up of a greater number of parts than a conventional system, including electrical components and extra tanks. The drain field for your system uses either natural or added materials to allow any dangerous bacteria or other contaminants to be filtered out before the water reaches the local groundwater. These chemicals will also make their way through your septic system and out onto the drain field, where people or animals may come into contact with the poisons. You might be pushing a lot of organic matter down the drain. Although aerobic systems are more sophisticated than standard ones, they still need routine maintenance in order to function at their peak. You will have had to ensure the soil is permeable, that the wastewater will not saturate nearby water tables and that the absorption of the wastewater into the soil will not be blocked or deviated by restrictions such as bedrock. ODEQ, 2012. You may be overloading the system with too much organic matter. it into non-polluting or relatively less-hazardous by-products. treatment prior to soil dispersal of wastewater are required in areas that have limitations Generally, a septic system must be cleaned every 3-5 years. After a period of low system activity, the microbial population needs time to rebuild so it can function well. We and our partners use cookies to Store and/or access information on a device. Like Schmellba said, most units run 10-15 minutes 2-4 times a day depending on use. designed to treat 266 gallons of waste water per day.

As the name suggests, such devices aid in the dispersal of effluent. In the case of maintenance, its important to ensure you stick to all use instructions regarding the safe use of this product. The most popular types of septic systems include conventional systems, chamber systems, aerobic treatment systems, and drip distribution systems. The type of soil used for treated wastewater dispersal is another consideration. So what type of septic system do you have, or what would you need if you were building a new home or renovating? settle and from the oil and grease that float. They remove 85% to 98% of the organic matter and solids from the wastewater, producing effluent as clean as effluent that comes from municipal wastewater treatment plants, and cleaner than that from conventional septic tanks. Do not use pool chlorine as this will not disinfect the wastewater. At REFERENCES we cite these sources. However, since the latter sprinkle treated wastewater with which humans can come into contact, it requires very efficient pretreatment. Small Field Size | Out-Of-SIght Soil-Type Restrictions. Divert surface waters (runoff and water from gutters) away from the tanks and dispersal Aerobic treatments processes greatly lower biochemical oxygen demand (BOD), a common measure of pollution, as well as reduce the suspended solids that do not settle to the bottom of the clarifier. Check the air pump to make sure the airflow rate entering the aeration chamber is constant. 2008. If they are broken, replace them the same type and model as the original. Equalization tanks may need to be cleaned out every one to two years. leading to a higher rate of microbial activity inside the chamber. Lesikar, B. Using an ATU (Aeration Treatment Unit) septic system installation to achieve a type 2 can range from $25,000 $35,000, Using an ATU with a subsurface drip line can range from $25,000 $35,000 depending on the topography, Using an ATU with an Evotranspiration bed can cost between $25,000 $40,000 depending on the home. Overloading water to the system, such as when fixtures leak or too much laundry is washed on a single day, dilutes the microbes food source. Traditional anaerobic septic systems involve the use of bacteria that don't require oxygen to live. sprinklers must provide uniform distribution of effluent over the entire spray irrigation If dirt is seen to be the cause, consider cleaning with a garden hose before putting it back in its place. In the system, wastewater first enters the pretreatment tank or trash trap, which removes plastic objects and other solids that float or settle. line will depend upon the soil group (classified according to soil texture as indicated Black sprinklers for instance wont serve the purpose because they arent designed to withstand effluent pressure. A home that is used only periodically is likely to have trouble maintaining a decent quantity of aerobic microbes for treating wastewater. An aerobic septic system comprises four key components, which work together to treat wastewater well enough to be used to irrigate a lawn or sprayed over a ground surface. In addition to increasing the decomposition rate, the aerobic condition in the tank water use in the house. An example would be Amazon.

The air pump, located near the aerobic tank, compresses air to flow into the aeration chamber. For instance, if you push a lot of cleaning products into the system, that could mean the end of microbes. Lets take a look at these. Replacement. Disinfection is performed after the effluent has gone through the The variation in sprinkler heads follows the brand, size, and color of products. This promotes decomposition The size of the system for restaurants and other facilities with strong wastes is calculated by using both quantity and organic strength of the facilitys wastewater. When you use the system again, consciously reduce the for the ultimate dispersal of the effluent to the soil either by surface spray or or the wastewater application depth and the limiting subsurface layer which could The distribution field transports the wastewater from the aerobic tank to its distribution heads. Aerobic treatment units (ATUs) also popularly called aerobic septic systems are among the several types you can choose from. As far as keeping your aerobic septic system in tip-top condition is concerned, nothing can beat the effectiveness of regular maintenance. anaerobic and facultative (survives both in aerobic and anaerobic conditions) microorganisms Aerobic units, which are certified as class I aerobic systems, treat wastewater well enough to be used in conjunction with spray systems, which distribute treated wastewater over lawns. properly. Try to keep a landscape cover going in your spray field. Spray heads that are broken or not spraying correctly should be replaced with proper septic spray heads. For systems with subsurfacedrip irrigation, the drip lines should be buried eight to ten inches deep and installed according As such, their advice will be of great benefit. Get expert help if you notice any seeping. The distribution field comprises five components, which are as follows: An aerobic system treats effluent well enough for it to be safely used with a spray system, which distributes effluents over ground surfaces. Keep a record of the diagram of the tank, the location of the access ports and check The size of an aerobic septic system sprinkler head will be normally considered when discussing the types. This approach to choosing a system assumes that the wastewater includes an amount of organic matter common for homes; it may be inadequate for certain businesses.
