Leopold Disk Filter
Superior performance for tertiary treatment and reuse applications
The key is the unique design that directs flow between two rotating steel mesh screens. The continuous disk rotation brings solids into contact with the screens at an acute angle, trapping particles that are even smaller than the mesh size. The unit backwashes while remaining in service, presenting a fresh filter surface to influent flow, and leveling out forward flows to downstream disinfection. The Ultrascreen disk filter enhances all types of disinfection, lowering chlorine demand and increasing UV transmissivity.
The Ultrascreen disk filter’s many adjustable features allow you to adapt to changing conditions, adjusting the speed of rotation, wash cycle time and influent levels in the feed zones to optimize operations and conserve energy. The highly efficient backwash requires only 0.5 to 2% of forward flow, reducing pumping costs, and adding minimal additional loading to the headworks. Combined with the high flow and solids loading capacity, The Ultrascreen disk filter eliminates worries about peak flows or temporary clarifier upsets. It keeps you reliably operating and in compliance.
