The sewage is then pumped in to a bioreactor tank system , where oxygen is continuously introduced to encourage bacteria growth which feed on the sewage.
Then the effluent then overflows in to a clarification/ settling tank system where any solids that escape the bioreactor system are collected and pumped or gravitated back to the septic or collection tank.
From the clarification tank, the now clean and treated water overflows in to the last tank where sterilisation occurs using ozone or Ultra violet.
In the sterilisation tank is a submersible pump which will automatically pump the treated water to irrigation, or dams, rivers etc.
Periodically it may be necessary to use a “honeysucker” system to remove solids and sludge from the septic/collection tank.
