44 • August 2015 www.concreteproducts.com Company offers two ranges of filter presses—Acquae and Ignis—for concrete. The Acquae range has three models, 400 x 400 BWR, 800 x 800 BWR and 630 x 630 BWR; Ignis two, 800 x 800 BWR and 1000 X 1000 BWR. Plant size and plate size vary by model. For instance, the Acquae 630 x 630 BWR is offered in seven different sizes ranging from 2,880- x 1,200-mm (630/10) and 11,825- x 1,200-mm (630/50), each with a 630- x 630-mm plate. Matec also customizes systems to specific plant needs. The filter presses are made of single-block steel from thick slabs, realized through plasma, laser or water-jet manufacturing process. Typical moisture content of processed cakes is less than 25 percent. Matec quotes hourly capacity/solid recovery based on number of mix- er trucks and NRMCA average for washout volume. The filter presses feature HPT pumps to work at more than 20 bar, Gasser Shakers for discharging the cakes perfectly, and Allen Bradley PLC system with remote monitoring and assistance. — www.matecamerica.com INNOVATIONS REPORT ENVIRONMENTAL Filter Press Equipment Challenges to optimize yard space utilization, step up water and material recycling rates, and lower process-waste disposal costs are driving con- crete producers' adoption of equipment well established in the mining business. Filter presses used in tandem with concrete reclaimers accelerate the water recycling loop and limit landfill-bound material to low-moisture cakes of primarily cement fine composition. Along with the McLanahan Concrete Washout System on the preceding pages, Concrete Products examines additional filter press offerings. Louisville, Ky.-based Phoenix and Italian water filtra- tion solution specialist Fraccaroli & Balzan have part- nered to offer the advanced Recessed Chamber & Mem- brane filter presses in North America. The companies' waste water treatment and dewatering equipment engi- neering experience allows for what officials contend are superior products and services across all markets, including concrete and slurry fines recovery. The Phoenix/FB Model 630-8 Filter Press has an overall footprint of 13 ft. 5 in. x 7 ft. 6 in. and 630-mm (24.8 x 24.8 in.) square plates. Depending on the slur- ry characteristics, the machine's production rate is 20 gal./cycle with around seven to eight cycles per hour. The residual moisture is between 20 to 25 percent. Spe- cial features of the Phoenix/FB Model 630-8 Filter Press include an automatic cloth wash and cloth hydration automation for downtime. — www.dewater.com MATEC AMERICA PHOENIX PROCESS EQUIPMENT
