How it works…

Septic Chamber
Influent enters the chamber via the source whereby scum and solids capable of settling are separated from the raw influent. Primary treated effluent flows through a transfer port to the aeration tank. This tank will also act as a storage chamber for sludge returned via the Clarification Chamber.
Aeration Chamber
Water enters via the Primary Chamber. Air is introduced into this chamber via an air blower to create an environment for aerobic bacteria and other helpful organisms to consume the organic matter present. The aeration tank helps prevent short-circuiting of the wastewater to ensure extended aeration. Media is also present in the tank to support the growth of bacteria.
Clarification Chamber
The Clarification chamber is essentially a quiescent zone where suspended particles/solids are settled out of the water. These particles are returned to either the septic or aeration chambers via a sludge return which aids in further biological reduction, de-nitrification and providing a constant food supply rich in microbes supporting the system through periods of limited flows.
Chlorination
Disinfection is achieved via low doses of chlorine to kill off any remaining harmful organisms. This process is completed through an automatic chlorinator with sufficient doses to last between maintenance visits.
