Introduction


With ISO9000 & CE certificates, the Multi-disk Screw Press developed by Benenv follows the dewatering principles of force-water current, thin-layer dewatering, moderate pressure and extension of the sludge dewatering path. It is able to treat low concentration sludge and oily sludge effectively, with low energy consumption and easy operation. This Multi-plate Screw Press realizes an energy-efficiently sludge dewatering.

Functional Principle
Layers of spacers, fixed and moving rings construct the dewatering cylinder. Moving rings, which are slightly smaller than the outer diameter of the screw and slightly narrower than the spacers, are located between the fixed rings. Edge of the screw pushes these moving rings in continuous circular motion.
The moving rings continuously clean sludge out of the gaps, prevents clogging and reduces the use of rinsing water.

Case Study

Problem

Famous for its production and sales of pork, Huayun Livestock had been facing heavy labor of sludge excess treatment. Advantages such as free from clogging, self- washing structure, and automatic operation can reduce working pressure and save lot of time and labor. And the sludge cake discharged by MDS press are used for fertilization, and the fertilizer are sold as commodity, realized the 0 sludge treatment cost. The director of Huayun Livestock products highly praised the MDS press.

BENENV's offer for a solution

Multi-Disk Screw Press with its clog-free-self-cleaning structure allows fully-automatic operation and these characteristics considerably minimized their burdensome works. As a result, they now have enough time for their main work, which is taking care of pigs rather than sludge handling.
In addition, they now make compost out of the sludge cake discharged from Multi-Disk Screw Press by using a composting unit. The compost made is sold as a product and they now pay "zero cost" for sludge disposal.
We are honored to be praised by factory director: Multi-Disk Screw Press has made our work easy. "
