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.

Advantages


1. One-in-all design, fits in small facility
Multi-Disk Screw Press adopted the unified structure that serves two functions, thickening and dewatering in the single machinery. The drum filter, because of the clog-free, realizes higher speed of filtering phenomena per filtering area as compared to other methods. For this reason, low concentration sludge of about Total Solids 0.2%, as well as thickened sludge, can be directly fed without pre-thickening.

2. Applicable to sludge in various kinds of applications

Municipal water and wastewater treatment plants
Agricultural/fishery community wastewater treatment plants
Industrial waste treatment plants
Food/beverage production plants
Dairy farming/Meat processing plants
Chemicals manufacturing plants
Machinery manufacturing/Metal processing plants
Laundry wastewater
Other (paper manufacturing, building material manufacturing, oilfield associated water accompanied with crude oil mining, etc. )

3. Wide range of line-up/Small footprint

The model of sludge dewatering press based on the customer needs can be selected from a wide range of line-up, and can be installed in places where placement would not be possible with other technologies for reasons such as low building ceilings or limited area. This makes Multi-Disk Screw Press suitable to customers who are considering the replacement of existing dewatering equipment.

4. Easy operation/Easy maintenance


Full automatic 24-hour operation without an operator on-site is possible with automatic operation control using various sensors. With this function, manual operation, such as starting or stopping, is not required. Moreover, daily maintenance is minimized, requires no skilled labor neither special knowledge, so that everybody can use it easily.

5. Power and water saving

The screw which is the main component rotates very slowly at a rate of 2 to 4 rpm, so that it consumes very low power and thus economical. Multi-Disk Screw Press prevents filter mesh from clogging with its unique self-cleaning mechanism, removing the need for huge amounts of water for clogging prevention.

Case reference

Shandong Qufu Huayun livestock products plant

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.

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.
