The process

The process of treating the sewerage can be simplified in the following 5 steps:

1.     Sewerage enters the inner chamber via the inlet pipe

2.     Air surges up from the draft tube to aerate the solids and liquids for a minimum of 24 hours

3.     More sewerage enters the inner chamber and an equal amount of effluent displaces through the into the outer chamber (at the bottom of the inner chamber)

4.     Suspended solids sink to the base of the clarifier and are drawn back up the draft tube for further digestion

5.     Clear effluent rises to the top of the clarifier and passes over the weir into the outlet pipe
