Product Description
Waste water recycling system vertical screw press sludge treatment volute dewatering screw press machine
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.

| 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 main function of the waste water recycling system vertical screw press is to dehydrate sludge through solid-liquid separation using screw extrusion principles.
The RDL131 model has a dry sludge treating capacity of 6-12 kg/h.
The output sludge moisture content is typically between 75-85%.
The screw body is made of SS304, SS316, or SS2205 materials, which provide durability and resistance to corrosion.
No, this type of dehydrator does not require cleaning as the moving ring in the filtering device is always in motion, preventing clogging.
The power consumption of the machine is 0.36 kW, and it has a water consumption of 28 L/h.
The required water supply pressure for operation is ≥0.2 MPa.
Polymer flocculation is used as a conditioning agent before dehydration, specifically with 2-8g-PAM/kg-DS when the concentration of PAM is 0.1-0.2%.
The dimensions of the machine are 2000 mm in length, 790 mm in width, and 1040 mm in height.
Yes, the electronic control system can be customized according to customer requirements and can include PLC and communication modules.
The machine includes various pipe ports for sludge inlet, filtrate outlet, return flow, sewage outlet, flushing water inlet, and polymer inlet, with specified flange and thread connections.
The net weight of the machine is 250 kg, while the operating weight is 390 kg.
The operation principle is based on screw extrusion, where the rotating screw exerts pressure to dehydrate sludge while filtering out liquid.
