The first step of a CAS system is the aeration tank where the wastewater is mixed with air to activate micro-organisms.

Activated Sludge Process Explained ASP

Activated Sludge Process. The Activated Sludge Process (ASP) is a sewage treatment process in which air or oxygen is blown into raw unsettled sewage to smash the solids and develop a biological soup which digests the organic content and pollutants in the sewage. These plants do not have a primary settlement chamber which is the chamber that needs emptying by tanker on a regular basis
