Product Description

Slurry Treatment System and Screw Press Separator Equipment Water Sludge Separator

Multi-disc Screw Press Dehydrator which uses the screw extrusion principle is a new type of solid-liquid separation device. It reaches the goal of extrusion dewatering sludge by powerful extrusion pressure of changing the screw diameter and distance, and the tiny spacing between moveable annular plates and fixed annular plates.

The core component of Multi-disc screw press dehydrator is the screw body, screw body has configuration with screw surrounded by filtering devices which have moving rings and fixed rings combined together and lined up.

As screw rotates, screw filters and dehydrates sludge while it is conveying sludge. Moving ring of the filtering device is moved upward as screw rotates and water was discharged from the gap made between the moving ring and fixed ring, so that sludge is filtered and dehydrated.The space between the screw and filtering device configured by fixed ring and moving ring becomes narrower as it comes nearer to outlet. Pressure which squeeze sludge become bigger as the sludge moves toward to the outlet, so that the sludge is filtered and dehydrated tightly.

This type of dehydrator doesn’t need cleaning since moving ring in the filtering device is always being moved by the rotating screws and clogging never happen. Therefore, in some wastewater treatment plants, waste sludge pulled out from aeration tank can be dehydrated directly without condensation. Polymer flocculation is used in conditioning before the dehydration.

Frequently Asked Questions

What is a Slurry Treatment System and Screw Press Separator?

The Slurry Treatment System and Screw Press Separator is a solid-liquid separation device that utilizes the screw extrusion principle to dewater sludge effectively through powerful extrusion pressure.

How does the Multi-disc Screw Press Dehydrator work?

It works by rotating a screw that filters and dehydrates sludge as it conveys it. The moving rings in the filtering device adjust to create pressure, squeezing out water from the sludge.

What are the main benefits of using this system?

The system offers efficient dewatering without the need for cleaning, reduced clogging, and the ability to dehydrate waste sludge directly from aeration tanks.

What is the treating capacity of the RDL131 model?

The RDL131 model has a dry sludge treating capacity of 6-12 kg/h.

What is the moisture content of the output sludge?

The output sludge moisture content ranges from 75% to 85%.

What type of power supply is required for this system?

The power supply can be customized according to the customer's requirements.

What are the dimensions of the system?

The system measures 2000 mm in length, 790 mm in width, and 1040 mm in height.

What materials are used in the construction of the system?

The screw body and mixing tank can be made from SS304, SS316, or SS2205, while the electric control panel is made from SS304 or SS316.

How much water does the system consume?

The water consumption of the system is approximately 28 L/h.
