Prime Rotary Fan Press
Available from Prime Solution Inc.
The Prime Rotary Fan Press is a dewatering technology for industrial and municipal customers requiring liquid/solid separation of sludges and slurries. It produces it produces dry cake solids ranging from 18-26% for anaerobically digested biosolids, 15-20% for aerobically digested biosolids and 20-32% for mixed primary and secondary sludges.
Approved by the EPA as an accepted dewatering technology, the Prime Rotary Fan Press reduces maintenance and energy costs with a slow rotational speed of 1 RPM.
Its system has a continuous dewatering process that is totally enclosed, eliminating odor and reducing corrosive exposure to nearby equipment.
Self-contained skid, mobile and modular units require little supervision and have a semi-automated self-clean cycle. They install easily and lower utility requirements to cut building costs.
Small Footprint, High Throughput
Units are compact with footprints ranging from 40-80 square feet. Varying models produce a range of 100-2,000 pounds of dry sludge per hour.
Single or dual presses are available with 18-, 24, 36- and 48-inch screens.
How It Works
Material moves slowly toward the outlet, forming a cake. An adjustable, two-piece pneumatic restriction plate controls pressure at the outlet. The frictional force of the slow-moving filter plates and controlled outlet restriction produces cakes as dry as 60 percent solid.
