Detailed Product Description:

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.


 Features and 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 secret lies in the self-cleaning mechanism. The drum filter, because of the clog-free, realizes higher speed of filtering phenomena per filtering area as compared to other methods, and the sludge is instantly thickened by gravity. For this reason, low concentration sludge of about Total Solids 0.2%, as well as thickened sludge, can be directly fed without pre-thickening.

 

Traditional way of sludge treatment

2. Applicable to sludge in various kinds of applications

1) Municipal water and wastewater treatment

2) Agricultural/fishery community wastewater treatment  

3) Industrial waste treatment 

4) Food/beverage production waste treatment

5) Dairy farming/Meat processing wastewater treatment

6) Chemicals manufacturing wastewater treatment

7) Machinery manufacturing/Metal processing wastewater treatment

8) Laundry wastewater treatmen

9) Other wastewater treatment (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, from a super-small 0.5 kg-DS/h throughput to a large 780 kg-DS/h throughput. Likewise, sludge thickeners can be selected from 1 m3 to 90 m3/h capacity.

 

It can be installed in places where placement would not be possible with other technologies for reasons such as low building ceilings or limited area. Therefore, the construction cost of a large building for installation is not required. 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 of Volute rotates very slowly at a rate of 2 to 4 rpm, so that it consumes very low power and thus economical. When comparing Volute with centrifuge for 30 kg-DS/h throughput, the power consumption of Volute is 1/20th of centrifuge which requires rotation at high speed.

 

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. When compared with dewatering equipment of the same throughput, the amount of cleaning water required for Multi-Disk Screw Press is about 1/115th of belt press and about 1/12th of conventional screw press.

Case Study

 

Qujing City, Yunan Province, Sludge Treatment Plant

 

 

Problem

 he wastewater treatment plant of a town in Qujing, the long-used belt press was in a time to be overhauled. The person in charge had racked his brain over the problem of huge cost required to overhaul this equipment at regular intervals. He had been seeking a solution to this problem.

In addition, he had to cope with another knotty problem that a planned new construction of sludge treatment plant cost had to be lowered as possible. Furthermore, there had been multiple problems in this town in connection with sludge treatment including odor problem generated from the Sludge Thickening Storage Tank, the employment cost of resident staff to manage the existing dewatering equipment. 

 

 BENENV\'s offer for a solution

The encounter with Multi-Disk Screw Press resolved all these problems in this town. The person in charge started with setting up Multi-Disk Screw Press at a cost of overhauling the existing belt press, which allowed him to avoid the burden of regular huge overhaul cost. As concerns odor problem, one of the features of Multi-Disk Screw Press (direct dewatering system from OD tank) substantially-improved the odor. Multi-Disk Screw Press also allowed him to reduce resident staff to manage the equipment and the employment cost.
The introduction of Multi-Disk Screw Press was included in a new construction of sludge treatment plant in the basic design phase. With this introduction, there were no need of Sludge Thickening Tank and Sludge Storage Tank, which resulted in about 20 million yen reduction of construction cost.
