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.

The Five Star Disk Filter design allows you to change an existing filter cloth in a matter of seconds without taking the filter off-line.
Five Star conducted testing at Whispering Palms WPCF in Rancho Santa Fe, CA. These tests consist of evaluating a new design, more dense cloth for wastewater filtration. Tests were conducted at 10+ gpm/ft2 with great results. Influent was more than 6 NTU with filtrate less than 1.2 NTU. The second test evaluated the previuosly accepted cloth by CA DPH for Title 22 permited projects at 6 gpm/ft2. Tests were conducted at 12+ gpm/ft2 and have proved reliable with exceptional performace of less than 1.2 NTU in the filtrate.
As the air travels up the airlift the sand is fluidized, lifted, and empties into a counter-current washbox. Backwash is accomplished using filtered water, and provides a 8 gpm continuous reject stream. Video depicts airlift function without splashguard installed.
This is a video of the Five Star Disk Filter in operation at Bancroft WWTP. This plant runs with an average daily flow of 299 USgpm and a Peak Daily Flow at 514 USgpm. This is just one of the many packages that Five Star Filtration can offer for filtration needs.
This is a video of the Five Star Disk Filter in operation in Washington State.  This plant runs with an average daily flow of 835 USgpm and a Peak Daily Flow at 875 USgpm.  This is just one of the many packages that Five Star Filtration can offer for filtration needs.
This video demonstrates how easy installation of the Five Star Disk Filter is. After completion of this video all that is left to do is core holes for effluent pipes and backwash piping for cleaning mechanism.
