Wastewater enters the pre-treatment chamber where solids settle to the bottom.

The pre-treated wastewater is pumped to the treatment chamber.

The 6 hour treatment phase begins - the wastewater is intermittently supplied with bursts of oxygen. These bursts provide the microorganisms with required oxygen to begin their treatment process (denitrification).

After the 6 hour treatment phase a 1.2 hour sedimentation phase begins where sludge settles to the base and the treated wastewater clears.

The treated wastewater is then pumped out of the treatment chamber. After 8 hours the complete cycle has ended. In the case that sufficient wastewater is available in the pretreatment chamber, the entire 8 hours cycle begins again. In the case that no or little wastewater has been collected, the INNO-CLEAN automatically goes into energy savings mode.

Excess sludge is returned to the sludge storage tank.
