Screw Press in Sri Lanka
QuaSys Inc. is an authorized dealer and supplier of Screw Press sludge dewatering machines in Sri Lanka, providing energy-efficient screw press systems for continuous sludge dewatering in sewage treatment plants and effluent treatment plants. Our screw press machines reduce sludge volume by 80–90%, minimising disposal costs for Sri Lanka clients.
Sri Lanka's tourism-driven hospitality sector and growing industrial base require dependable water and wastewater treatment equipment. QuaSys Inc. exports its full product range to Sri Lankan clients, with shipments via Chennai or Tuticorin port to Colombo — one of our shortest and fastest export routes, typically 4–7 days transit.
✅ QuaSys Inc. — Authorized dealer with 20+ years experience and 500+ installations. We export genuine Screw Press Sludge Dewatering to clients in Sri Lanka with full documentation and post-sales support.
What is a Screw Press?
A Screw Press is a continuous mechanical sludge dewatering machine that uses a slowly rotating screw to compress and dewater biological or chemical sludge from STP and ETP systems. The screw rotates inside a cylindrical filtering screen, advancing sludge from the feed end to the discharge end while progressively squeezing out filtrate water through the screen openings.
Screw press machines operate at very low speed (2–5 RPM), consume less power than filter presses or centrifuges, and generate minimal noise. They operate continuously without operator intervention, require minimal maintenance, and produce dewatered sludge cake with 18–25% dry solids content suitable for composting or disposal.

Frequently Asked Questions — Screw Press in Sri Lanka
What is the price of a Screw Press in Sri Lanka?+
Screw press pricing in Sri Lanka varies significantly with capacity — a small 1-5 kg DS/hr unit and a large 200-500 kg DS/hr machine are very different investments. QuaSys Inc. provides a project-specific quotation once we understand your sludge volume and characteristics for Sri Lanka. Call +91 95408 15659 for a free quote.
What cake dryness can a screw press achieve?+
Screw press machines typically achieve 18–25% dry solids content in the dewatered sludge cake. This depends on sludge type (biological vs chemical), polymer dosage, and screen slot size. Biological activated sludge from STPs typically dewaters to 18–22% DS. QuaSys optimises polymer dosing for maximum dryness at your Sri Lanka plant.
How does a screw press compare to a filter press or centrifuge?+
Screw press: continuous operation, lowest power (0.5–3 kW), lowest maintenance, 18–22% cake DS. Filter press: batch operation, high labour, 30–40% cake DS, higher polymer cost. Centrifuge: continuous, high power (15–30 kW), higher maintenance, 20–25% cake DS. For most STP applications in Sri Lanka, screw press is the optimal choice on lifecycle cost.
Does the screw press require polymer conditioning?+
Yes. Biological sludge requires polymer (polyelectrolyte) conditioning before screw press dewatering to aggregate fine particles for effective water release. QuaSys supplies integrated polymer preparation and dosing units with the screw press for Sri Lanka projects, with polymer dosage optimised during commissioning.
How long do screw press screen segments last?+
Screen segments (the cylindrical filtering screen) typically last 3–7 years depending on sludge abrasiveness and operating hours. QuaSys stocks replacement screen segments for common screw press models and dispatches to Sri Lanka clients for scheduled replacement.
