Filter press line solidifies Enviro-Port reclaiming role

A filter press series from D.R. Sperry & Co. of Aurora, Ill., has joined Enviro-Port’s line of concrete reclaiming and slurry handling equipment.A filter press series from D.R. Sperry & Co. of Aurora, Ill., has joined Enviro-Port’s line of concrete reclaiming and slurry handling equipment. Filter presses enable producers to reduce settling pond sediment handling requirements and solids drying time, while also expediting the return of water for process and batch use.

Presses are most efficient when used with a reclaimer system directly connected to a tank or cell running an agitator pump kit or impeller and gearbox drive. In concrete production, they a) remove particulates from gray water, pressing them into easily handled cakes; and, b) yield low solids content, filtered water.

Although in its concrete industry infancy, filter press technology has existed for years. Enviro-Port underscores the Sperry filter press’ potential for integration and enhancement of gray water reclamation systems; reducing process water solids to transportable cakes with low moisture content; water clarification; and, low-cost operation. In typical concrete operations using agitated tanks, suspended solids range from 10–20 percent by weight. The filter can remove nearly all the solids when efficient agitation accompanies press-bound water.

Enviro-Port offers four Sperry models. At 470-mm with 2.5-cu.-ft. press, the smallest can process up to 8,000 gal. daily and suits precast plants or ready mixed operations with 10 or fewer trucks. Three additional models are sized to ready mixed plants with up 15, 25 and 35 trucks, respectively: 630-mm, 4.2-cu.-ft. press, 17,000 gal. capacity; 800-mm, 8.5-cu.-ft. press, 26,000 gal.; and, 1,000-mm, 20-cu.-ft. press, 35,000 gal. Model choice can also hinge on producers’ use of gray water in batching and whether filter press operation is continuous or inclined to production peaks.

Enviro-Port’s Gray Water Rebatching Technology, coupled with Sperry filter presses, elevates the reclamation process and reduces plants’ carbon footprint through lower waste handling and hauling requirements. Ready mixed and precast concrete producers can look to Enviro-Port for assistance in achieving all their gray water processing goals, company officials note. — Enviro-Port Inc., 800/356-8106; www.enviro-port.com
