Sludge dewatering is the separation of a liquid and solid phase whereby. Generally, the least possible residual moisture is required in the solid phase. Meanwhile, the lowest possible solid particle residues are required in the separated liquid phase.
A typical example of this type of two-phase separation is the dewatering of sludge from municipal sewage plant or industrial waste water treatment. In this case, the residual moisture in the dewatered solid determines the disposal costs and the separated liquid determines the pollution load returned back to the treatment facility. Minimizing both must be achieved at the lowest possible cost, with the lowest possible polymer and energy consumption, with low maintenance costs and with the lowest possible number of required operating staff.
In the whole sludge dewatering system, the sludge dewatering device Volute Screw Press and Belt Filter Press are core product series of BOEEP, which have a very high market share nowadays. Usually, different kinds of sludge will be produced during water processing. The sludge dewatering devices are mainly used to decrease water content, reduce sludge volume, and make the processing of the next sludge treating step easier. Volute Screw Press and Belt Filter Press are widely used in the wastewater treatment market. After many years of production experience and market development, we have studied these two products in depth. In the process of improving the performance and quality of the conventional ones, a lot of subdivision products have been developed.
