Volute Sludge Dewatering Machine

High-Performance Volute Sludge Dewatering Machine for Oily & Municipal Sludge

Clog-Free, Low-Energy Sludge Volume Reduction Engineered to German DIN Standards.

The Industry Challenge :
Traditional belt presses and centrifuges face severe challenges when processing biological or oily sludge. They consume massive amounts of electricity, require constant backwashing water, and suffer from frequent filter cloth blinding, leading to high OPEX and operational downtime.

The Feiran EP Solution :
Our Volute Sludge Dewatering Press utilizes a multi-disk screw press technology that eliminates the need for filter cloths. Operating at an ultra-low speed of 2-4 RPM, the alternating fixed and moving rings create a continuous self-cleaning mechanism. This ensures uninterrupted dewatering even with highly viscous and oily sludge, dropping your total operational costs by up to 60%.

Q1: Can the volute sludge dewatering machine handle high-oil-content wastewater?

Yes. Unlike belt presses that blind easily, the Feiran EP volute press features a dynamic self-cleaning ring mechanism. This allows it to efficiently dewater oily sludge from food processing, chemical, and petrochemical plants without clogging.

The Feiran volute press operates at a very low rotational speed (2-4 RPM). This results in power consumption that is typically less than 5% of a standard decanter centrifuge of similar capacity, significantly maximizing your ROI.

Maintenance is minimal. There are no filter cloths to replace or high-speed bearings to lubricate. The primary wear parts are the moving rings and the screw shaft, which are reinforced with hard-facing treatments to ensure years of continuous operation.
