Our innovative screw press technology combines sludge concentration and dewatering in a single compact unit, eliminating the need for separate processing systems. The unique design features interlocking fixed and movable rings working in perfect harmony around a central screw shaft, enabling reliable processing of even the most challenging sludge types—including high-oil-content sludge that cripples traditional dewatering machines.
Below we explain how our volute press works, its industry-leading features and how it can reduce your operational costs while improving environmental compliance.
The volute dewatering equipment is a next-generation solid-liquid separation device that leverages proven mechanical extrusion principles of screw press technology.
Unlike traditional belt filter presses or plate-and-frame presses that rely on filter cloths (prone to clogging and frequent replacement), our system generates powerful dewatering pressure through three key mechanisms:
Variable screw diameter that increases compression along the shaft
Progressive reduction in screw pitch from the inlet to the outlet
Tight, precision-engineered clearance between movable and fixed annular plates
This integrated design seamlessly combines sludge thickening and dewatering in one continuous process. Sludge enters the thickening department where free water is removed, then moves to the dewatering department where mechanical pressure squeezes out remaining water, producing a dry, compact sludge cake ready for disposal. The entire process streamlines your wastewater treatment workflow and eliminates bottlenecks associated with multi-stage systems.
Our patented dynamic and static ring design completely eliminates filter cloth clogging—the single biggest pain point of traditional dewatering equipment. The movable rings continuously scrub the gaps between fixed rings during operation, preventing buildup and ensuring consistent performance. This innovation reduces cleaning water usage by up to 80%, eliminates internal circulation burdens and makes our equipment uniquely suited for oily sludge treatment.
Operating at an incredibly slow rotational speed of only 2-3 revolutions per minute, our volute press consumes up to 70% less power than high-speed belt filter presses. This dramatic reduction in energy use translates directly to lower monthly utility bills and a smaller carbon footprint for your facility.
The integrated intelligent control panel manages the entire treatment process automatically—from sludge pumping and flocculant dosing to sludge cake discharge. No constant manual oversight is required, allowing your staff to focus on other critical tasks. This fully automated system enables uninterrupted 24/7 operation, reducing labor costs by up to 80% and maximizing throughput.
All wetted parts are constructed from premium SS304 or corrosion-resistant SS316 stainless steel, ensuring exceptional durability and longevity even in harsh industrial environments. This robust construction minimizes wear and tear, extending equipment service life to 10+ years.
By integrating sludge thickening and dewatering in a single unit, our equipment saves up to 50% of valuable floor space compared to separate systems. The compact footprint makes it ideal for retrofitting existing facilities or installing in space-constrained locations.
Our volute press operates under aerobic conditions during dewatering, preventing phosphorus release that occurs under anoxic or anaerobic conditions in traditional systems. This significantly improves overall phosphorus removal efficiency, helping you meet strict environmental discharge standards.
Thanks to the self-cleaning design and rugged construction, maintenance is extremely minimal. Only periodic inspections and replacement of the screw shaft and movable rings are required (every 3-5 years depending on usage), minimizing downtime and maintenance costs.
Our equipment effectively processes a wide range of sludge types, including high-density, low-density and especially oily sludge. This versatility makes it suitable for virtually any wastewater treatment application.
