Volute screw press sludge dehydrator/Algae sludge dewatering machine manufacturer

The sludge dewatering equipment is a new kind of sewage treatment facility developed by GNGTHISM. It uses multi laminated filter and spiral rotation to separate moisture from sludge. Benefiting by the special structure of fixed rings and moving rings, it allows continuous automatic operation in 24 hours without blocking. And our sludge dewatering equipment is competitive in current market for more than4 years' experience and ISO, CE certification.

Key features
♦ Energy, water, polymer saving
♦ Compact design, small floor space
♦ Low-speed operation, low power consumption and noise
♦ Self-cleaning, free of clogging, easy to handle oily sludge
♦ 24h automatic continuous control, simple operation and maintenance
♦ Widely applied in municipal sewage, papermaking, chemical industry, food and beverage processing, pharmacy, petroleum refining and extraction, breeding and slaughtering and other industrial wastewater

Working Principle

As equipment starts running, sludge flows into the filter cylinder and moves forward to sludge cake outlet under the thrust from screwshaft. The whole filter cylinder is composed of fixed rings, moving rings and shaft. The first two sections are thickening zone, last two are dewatering zone, The space between screw blades gets more and narrower, which means the inner pressure gradually gets bigger. Under this pressure, liquid is squeezed out from the sludge and leaks from the small gaps between rings. And the left dry solid is pushed to the sludge cake outlet.
