THE PROCESS OF TREATING THE SEWAGE IN 6 SIMPLE STEPS:
- Sewage enters the inner chamber via the inlet pipe
- Air surges up from the draft tube to aerate the solids and liquids for a minimum of 24 hours
- More sewage enters the inner chamber and an equal amount of effluent displaces through the into the outer chamber (at the bottom of the inner chamber)
- Suspended solids sink to the base of the clarifier and are drawn back up the draft tube for further digestion
- A small quantity of settled effluent from the top of the outer ring clarifying chamber, is drawn back into the centre aeration chamber by a simple airlift system for further digestion.
- Clear effluent rises to the top of the clarifier and passes over the weir into the outlet pipe
