The Aerobic Wastewater Treatment Systems have been designed and built to provide long term, reliable, and cost efficient service. This treatment plant will operate with a minimal amount of attention; however, there are a few things you should know in order for your system to maintain its biological stability and give you years of outstanding performance.
Your local regulating authorities and designers have sized your Aerobic Wastewater Treatment System for your home. This means you should try to maintain a certain amount of daily flow into the system.
Size Safe Zone
· 500 Gallons per day 350 – 500 Gallons per day
· 600 Gallons per day 450 – 600 Gallons per day
· 800 Gallons per Day 550 – 800 Gallons per day
· 1000 Gallons per Day 800 – 1000 Gallons per day
· 1500 Gallons per Day 1300 – 1500 Gallons per day
The Aerobic Wastewater Treatment System is similar to large municipality sewage treatment plants. It uses an extended aeration activated sludge process. This type of treatment depends primarily on the use of air. When air is introduced to the wastewater, it promotes the growth of aerobic bacteria and other microorganisms that break down the organic material found in regular household sewage.
Raw unsettled waste/water from you home enters directly into the pretreatment tank. Inside the pretreatment tank, the solids separate from the liquid and the liquid flows into the aeration chamber. Inside the aeration chamber, simple hydraulic displacement is accomplished by the introduction of air. Air is introduced into the aeration chamber by passing from the aerator motor through the air diffuser and into the system. This air promotes the growth of aerobic organisms in much larger amounts than would naturally occur. It is these aerobic organisms (bacteria) that break down the organic material. As the wastewater leaves the aeration chamber, it enters the “quiet zone” better known as the clarifier. No mixing occurs inside the clarifier.
In the clarifier, any “leftover” solids separate from the liquid and settle to the bottom of the clarifier. This solid material is called sludge. Sludge contains dissolved oxygen and the sludge bacteria are activated by oxygen. This activated sludge is returned to the aeration chamber where it is mixed and digested again. The sludge then mixes with incoming wastewater. This mixture of returned sludge, wastewater, and dissolved oxygen is referred to as mixed liquor. The mixed liquor flows back into the clarifier, the solids separate and return once again to the aeration chamber. This never-ending cycle produces a clear, odorless, high quality effluent that is ready to be released to the environment.
The Aerobic Wastewater Treatment System is much like a living organism. It needs certain things to work and perform properly. Your system can treat most any type of household wastewater. This includes the waste/waters from showers and baths, clothes, and dishes, and toilets. However, as great as the system performs in treating common household sewage, it cannot treat everything flushed from the house. For a more descriptive list of items that the system cannot treat, se the list titled as “Items That Are Not Safe To Use In Your System”
Think of your system as a way for bacteria to live. This means anything that you use in your home
could affect the performance of the system.
It is acceptable to use household cleaners as long as they are not over used. By following the directions on the labels, you should be fine with the amount of chemicals being introduced into the system.
Other than regular household sewage and minor use of cleaners, no other products should be introduced into the system.
The proper operation of the septic system depends upon proper organic loading and the life of the aerobic bacteria inside the system.
Ø Do not put strong disinfectants, bleaches, toilet cleaners or sanitizers, other than small amounts used in daily house cleaning and laundry, into the system (follow manufacturer’s instructions). Do not use liquid fabric softeners.
Ø Do not put chemicals that have high volumes of bacteria killing agents into your system. Do not put commercial, industrial, or chemical waste into your system.
Ø Do not allow any discharge, backwash, and/or exhaust from any type of water softener to enter the system. Do not allow surface water to pond around the system. Do not allow non-sewage water flows caused by rain or ground water infiltration, storm water infiltration, leakage from improperly maintained plumbing fixtures, excessive volumes of water, etc. to enter the system. Do not allow air conditioner condensation lines, other than those a/c lines installed to directly discharge into the pump tank, to flow into your septic system.
Ø Do not put coffee grounds, shrimp shells, food waste or any level of cooking grease and/or oils into the system.
Ø Do not allow pet shampoo or pet dip to flow into the system
