Coagulation filtration processes collect contaminants that have been coagulated in the influent water onto a selected filter media. At regular intervals, the media undergoes automatic backwashing, with backwash water captured in settling tanks. The precipitate in the backwash tank settles to the bottom of the tank and is periodically removed for disposal via tanker truck. After settling occurs, a majority of the backwash supernatant is recycled through the process, maximizing the efficiency of the system.
