www.concreteproducts.com August 2015 • 45 INNOVATIONS REPORT FILTER PRESS EQUIPMENT The company's EnviroSystem provides operators with the ability to remove cement and sand solids, usually after a reclaimer, and to produce a clear effluent that can be reused in truck and mixer wash outs. It can be custom designed to meet the needs of any size operation. If desired, the pH can be adjusted to neutral levels allowing the effluent to be reused 100 percent in the batch process—meeting industry specs. The company's 100-percent closed-loop solution meets Environmental Protection Agency thresholds and elimi- nates any discharge to a city sewer, all with- out the use of any settling chemicals. Small operations may choose a 6-cu.- ft. press, while larger operations opt for a 25-cu.-ft. press. However, there is no limita- tion on the size of the filter press that the com- pany can provide. Plates begin at 630 mm and increase in size based on the design to 800 mm, 1,000 mm, 1,200 mm, and larger. Filter plates and cloths are made of polypropylene. Moisture content of processed cakes is 50 per- cent or lower, depending on the need and the design. The company provides coast-to-coast service in the U.S. and Canada. Additional- ly, all system components are stocked in the U.S. with next day shipment guaranteed. — www.watertreatmentonline.com Si x f i l t e r p re s s mo de ls — F P 4 7 0 2 0 C , F P 6 3 0 2 0 C , F P 6 3 0 5 0 C , F P 8 0 0 4 0 C , FP100045C and FP150045C—are engi- neered to operate without clarifying or thickening tanks.
