201 Screw Dehydrator for Efficient Sludge Dewatering
We are pleased to introduce our 201 screw dehydrator, a compact and highly efficient sludge dewatering solution designed for small to medium-scale wastewater treatment applications. This model is part of our trusted screw press series, offering reliable performance, low energy consumption, and minimal maintenance requirements.
The 201 screw dehydrator features a unique slow-rotating screw shaft enclosed in a cylindrical screen cage. As sludge enters the unit, the screw conveys the material forward while gradually increasing pressure. This gentle but effective dewatering process forces free water out through the screen openings, producing a dry, stackable cake at the discharge end.
Key Advantages of the 201 Screw Dehydrator:
✅ Compact footprint – Ideal for facilities with limited space. The 201 model occupies approximately 30% less floor area than conventional belt presses.
✅ Energy-efficient – The slow rotation speed (typically 2–5 RPM) consumes only 0.5–1.5 kWh per ton of sludge, saving up to 60% energy compared to centrifuges.
✅ Self-cleaning design – The unique screw and ring configuration prevents clogging, even with oily or fibrous sludge. No continuous wash water required.
✅ Fully automatic operation – The 201 screw dehydrator can run unattended for 24/7 cycles, reducing labor costs.
✅ Low maintenance – With no complex hydraulics or high-speed bearings, maintenance intervals are extended. The stainless steel construction ensures corrosion resistance.
✅ Adjustable dewatering performance – By varying the back-pressure plate, operators can control the dryness of the discharged cake, typically achieving 15–25% DS (dry solids) for organic sludge and up to 30–40% for inorganic sludge.
Typical Applications:
Municipal wastewater treatment plants (small to medium flow)
Food and beverage processing (dairy, brewery, slaughterhouse)
Livestock and poultry farms (manure treatment)
Industrial effluent (textile, paper, chemical, pharmaceutical)
Septic tank sludge and grease trap waste

Why Choose the 201 Screw Dehydrator?
Unlike traditional filter presses or belt presses, the screw dehydrator operates continuously, requires no operator attendance, and produces a cleaner filtrate with lower suspended solids. The 201 model is particularly popular for decentralized treatment and retrofit projects where space and budget are constraints.
Our factory pre-tests every 201 screw dehydrator before delivery. We also provide optional polymer dosing systems and control panels to create a complete dewatering package.
