A Question often asked is:

“What happens to the sludge that carries over from the primary tank and that every one accepts is the cause of progressive failure in conventional septic trenches, the destruction of subsurface irrigation and disruption and failure of the treatment process in mechanical treatment systems?”

THE ANSWER:  Aerobic and Anaerobic bacteria digest it.

The Advanced Enviro-Septic™ Wastewater Treatment System in essence creates a self-sustaining, self regulating biological ecosystem which is highly effective at purifying effluent. The bacterial population within the system adjusts as it is exposed to cycling aerobic and anaerobic (wet and dry) conditions. The aerobic and anaerobic bacteria populations automatically adjust based on what they are “fed” (the waste that is introduced to the system for processing) and the amount of oxygen present in the system. The bio mat (a microscopic layer created by the waste-products of anaerobic bacterial activity) is responsible for treating the wastewater and regulating the rate at which fluid moves through the system. Slowing down the liquid enables the bacteria (both aerobic and anaerobic) the time it needs to digest the waste materials (suspended solids) in the effluent.

Last week we obtained photos of an AES system designed by Biowater design that has been installed on the Sunshine Coast for 3 years and 9 months. The photos clearly show how effective the anaerobic and aerobic bacteria are at regulating the treatment and flow through the biomass and AES fabric, protecting the system sand and the receiving soil.

This close up photo is of the sludge accumulation zone in the bottom of each rung of the AES pipe or the anaerobic zone within the AES pipe system. As the water level fluctuates this sludge zone provide a bacterial food source which can sustain the system for a considerable time.  If this is the total sludge accumulation in the AES pipe after almost 4 years, it is easy to understand that the biological process could easily sustain the sludge levels like this for  a very long time ensuring the sand stays is protected and kept as clean as the sand in the photo above.
