Introduction
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.

Guangzhou Cheng Kee Food Company
Problem
Since sludge dewatering equipment had not been installed in their wastewater treatment plant, sludge had been treated with a sand filter and took them 1 to 2 weeks to dry. Furthermore, the dried sludge had been picked up and placed in a tub by 30 employees, and it took them an hour to complete their task. It was not only time-consuming but also required high labor cost. However, this was not the only issues that they had been confronted with in sludge treatment.
Since the sand filter is installed outside, sludge treatment can be significantly influenced by the weather. For instance, there is a huge disparity in temperature between summer and winter, and this undesirable environment had affected their productivity to a great extent. Moreover, the fact that the time when the sludge dries depends on the weather made them difficult to treat sludge according to plan.
BENENV's offer for a solution
ChengKee Food decided to install Multi-Disk Screw Press in order to deal with all the issues that they had been confronted with. The installation brought tremendous changes to the company and they now no longer need to pick up dried sludge thereby saving time and cost. Moreover, Multi-Disk Screw Press can be operated automatically for 24 hours without an operator on site by setting the 24h timer. With this outstanding function, they now no longer need to wait for the sludge to dry thereby making them easy to treat sludge according plan. Overall, the installation of Multi-Disk Screw Press solved many of their issues including, high labor cost and inefficiency in sludge treatment. For that reason, they save more time, and the time now allows them to concentrate on their primary jobs. The employees are very pleased and satisfied with the installation of the Multi-Disk Screw Press.
