Disk Filter Page Main Content
The Five StarTM Disk Filter is engineered as a continuous operation system that utilizes a fixed filter disk and a rotating backwash system controlled by a PLC or relay control panel. All internal or submerged components are corrosion resistant stainless steel or non-metallic materials.
Use of the fixed-disk design reduces overall horsepower and permits removal of each individual disk while the filter remains in operation. The filter disks remain fixed while the rotating center shaft supports the backwash arms, and serves as a header for removal of solids from the filter. At the beginning of the timed backwash cycle, which is initiated by headloss across the filer, electrically actuated valves segregate the backwash header and clean the filer disks on that portion of the header. This insures complete cleaning of the filter cloth while minimizing the rate at which backwash water is returned to the treatment facility.
Performance of the Five Star Disk Filter is second to none. The cloth is capable of solids capture down to 10 micron without having to build up a filter mat or require any run-in time. The two-layer cloth allows for complete cleaning, utilizing filtered water from inside the disk. The filter cloth is supplied as a sealed bag that can be replaced and re-installed in a matter of minutes, all while the filter continues to function without interruption.
