Wastewater Technologies continues to expand its liquid/solid separation capabilities by adding a user-friendly, small footprint, low backwash, high performance tertiary filter for both small and large flow applications. The BioDISC™ Cloth Media Filter removes suspended solids as small as 10 microns and can be configured for flows as low as 100,000 GPD to over 6 MGD.
Filtration Principles
Influent enters the filter through a pipe that directs the flow toward the floor of the tank housing the filter discs. This approach uses the turbulence of the incoming flow to keep the solids in suspension and prevent premature settling. This simple design characteristic greatly reduces the amount of sludge accumulation in the bottom of the tank and significantly improves maintenance and cleaning.
The suspended solids are removed as the influent passes through the cloth filter media. Each filter disc is made up of two filter cartridges. Filtered flow from each cartridge is visible through individual discharge ports. This design characteristic allows the operator to monitor the operation of each cartridge and quickly isolate a problem. In the event of a problem, each cartridge is easily replaceable without taking the entire filter off line. This is possible because the BioDISC™ panels do not rotate. The panels are stationary and the vacuum head rotates around the disc during the backwash cycle.
Applications
The BioDISC™ filter produces reuse quality effluent suitable for applications from golf course irrigation to cooling tower supply water.
