Fraccaroli e Balzan S.p.A., a world leader in the design and construction of waste water treatment plants and filter presses, has engineered a cost-effective, simple-to-use water treatment plant (solids separator) for the stone industry. This “compact unit” - available exclusively fromSalem Stoneof Winston-Salem, NC - can efficiently separate suspended particulates from the water used in any natural or engineered stone processing application, from sawing to edge profiling. Fraccaroli e Balzan reports that reclaiming and recycling process water will greatly cut production costs to any operation and will pay for itself in a short time in most applications. The compact unit is complete with a settling tank (decanter), clean water tank, pumps, filter press, panel board with PLC and all accessories. The system is built in a single piece, which makes the installation extremely quick and easy, according to the company, and the unit completely automatic, including the functioning of the filter press, so that no operator is required except for normal maintenance. The compact unit is also available in a larger version, without an incorporated clean water collection tank.
