How does the Rewatec ASP work?
The Rewatec ASP is a small sewage treatment plant. It is used to treat domestic wastewater and to provide a much cleaner effluent than a traditional septic tank.
Installed as an activated sludge system, the Rewatec ASP comprises of a single tank. Within this tank there is an inner central biozone chamber and an outer settlement zone.

The wastewater flows into the tank and settles in the central biozone chamber. This is where aeration occurs through the central diffuser.
The water then enters the outer settlement zone prior to discharge where a gravity or pumped option can be specified. Excess sludge is removed periodically by a local service professional.
