Easy-Operate Volute Screw Dewatering for Wastewater Treatment
Product Description
Features: User-Friendly and Versatile
Simple Operation for All Users
No Expert Training Needed: A single knob adjusts the screw speed, and color-coded indicators show when it’s time for routine maintenance (every 500 hours).
Plug-and-Play Setup: Connect to your sludge pump and power supply—no complex piping or electrical work. Most installations finish in under 3 hours.
Quiet Operation: ≤75dB noise level, thanks to the rubber-insulated screw housing—friendly for plants near residential areas.
Efficient Sludge Dewatering
Volute screw design with 10mm-thick threads squeezes out water effectively, achieving 25-30% solids content in the cake—ideal for landfill or composting.
Processes 8 m³/h of sludge, with a built-in screen (0.3mm pores) that traps particles as small as sand, reducing carryover to the effluent.
Self-cleaning function: Reverses screw rotation for 20 seconds every hour to prevent minor clogs—no need to stop the system.
Built for Longevity
316 stainless steel construction resists corrosion from acidic or alkaline wastewater (pH 4-12).
Heavy-duty bearings rated for 10,000 hours of continuous use—backed by our 3-year warranty on moving parts.
Applications: Wide-Ranging Wastewater Solutions
Municipal Treatment: Handles primary and secondary sludge from clarifiers and aeration tanks, common in cities like Phoenix and Houston.
Industrial Wastewater: Effective for textile dye sludge (high color), food processing sludge (organic matter), and automotive wash water sludge (oily solids).
Decentralized Systems: Perfect for rural wastewater plants or temporary treatment sites, where ease of operation is key.

Structure & Working Principle
The multiple fixed rings and moveable rings with the a screw shaft running through compose the main body of the Volute Screw Filter Press Sludge Dewatering Machine in which there are two sections. The front part is responsible for thickening and the ending part does the dewatering working. It can thicken and dewater sludge in one box. It has gradually taken place of the traditional filter clothes and centrifugal filtration method for its distinctive filter model.
After being thickened in the thickening part, the sludge will be transported to the dewatering part . In the course of progress, great pressure has been produced because the filter spacing and screw distance with the clogging of the back platen become smaller and smaller. Then the volume decreases continuously, and the purpose of fully dewatering will be achieved.
