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 BioDRUM™ Cloth Media Filter removes suspended solids as small as 10 microns and can be configured for flows as low as 4,000 GPD up to 165,000 GPD.
Filtration Principles
Influent enters the filter tank or clarifier and completely surrounds the drum. Suspended solids are removed as flow passes through the cloth filter media. Solids accumulating on the cloth will gradually restrict the flow of liquid through the cloth causing the water level to rise. When the level reaches a predetermined set point the backwash process begins.
Applications
The BioDRUM™ filter produces reuse quality effluent suitable for applications from golf course irrigation to cooling tower supply water.
