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 Patna
What is the price of a Screw Press in Patna?+
Screw press prices in Patna range from ₹5–8 Lakh for a small 1–5 kg DS/hr unit to ₹40–80 Lakh for large 200–500 kg DS/hr machines. Total installed system cost including polymer unit and panel is 20–30% higher. QuaSys provides detailed quotations for Patna clients — call +91 11 29531287.
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 Patna 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 Patna, 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 Patna 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 Patna clients for scheduled replacement.
