WXDL Series Screw Sludge Dewatering Machine Integrated Solid‑Liquid Separation Equipment for Municipal & Industrial Wastewater Treatment

WXDL Series Screw Sludge Dewatering Machine Integrated Solid‑Liquid Separation Equipment for Municipal & Industrial Wastewater Treatment

Brief Description

This WXDL series screw sludge dewatering machine is integrated solid‑liquid separation equipment for municipal & industrial sludge. It handles sludge concentration 5000‑50000 mg/L and runs 24h continuously. Multiple model options cover small‑to‑medium throughput for diverse wastewater projects.

Product Overview

The complete unit consists of dewatering main body, flocculation mixing system, built‑in spray washing assembly, electric control cabinet and auxiliary accessories. The filter stack is assembled by stacked fixed rings & moving rings with variable‑pitch screw spindle. Full‑range WXDL models offer dry‑sludge throughput from 5 kg/h up to 640 kg/h, covering small skid‑mount to heavy‑duty industrial units. It delivers stable dewatering performance under varied incoming sludge conditions.

Product Parameters

Working Principle

Flocculation‑conditioned sludge enters filter chamber from feed section. Driven by low‑speed variable‑frequency screw spindle, sludge firstly passes gravity thickening zone where free water drains through wider stack gaps. Then sludge moves into high‑pressure extrusion zone; decreasing chamber volume plus back‑pressure plate generates progressive squeezing force to squeeze bound water out. Dewatered sludge cake discharges continuously. Reciprocally‑sliding moving rings automatically clean filter gaps; built‑in spray washing further prevents clogging.

Key Design & Performance Features

1.Wide sludge concentration adaptability: 5000‑50000 mg/L inlet sludge.

2.Integrated unit design for easy installation.

3.24‑hour fully‑automatic continuous operation.

4.Self‑cleaning filter stack plus spray rinsing against blockage.

5.Fully‑enclosed structure to control odor emission.

6.Low‑speed spindle (2‑3 r/min), low vibration & noise.

7.Stainless‑steel key wetted components for corrosion resistance and long service intervals.

Applications

Municipal wastewater treatment plants, food & beverage processing, slaughterhouses, textile dyeing, papermaking, chemical manufacturing, pharmaceutical factories and general industrial wastewater facilities.
