As water flows through a filtration system, the media bed traps suspended solids while the filtered water passes to the service outlet. Once the filter media is fully loaded with suspended contaminants, the unwanted solids are then removed through a backwash cycle. This cycle purges contaminants on the media bed and sends them to a nearby drain. Typically, the filter control system automatically initiates the backwash cycle using a pressure differential switch or a time clock control. 

Chem-Aqua offers a complete line of media filtration to be able to customize a filtration system to suit your needs.
