Screw and filter housing made of duplex stainless steel (2205), with a corrosion resistance 5x higher than 316 stainless steel—ideal for pH 2-13 wastewater.
Tungsten carbide-coated feed hopper resists abrasion from crystalline solids in bioreactor sludge.
Processes 12 m³/h of sludge, achieving 35-40% solids content even for sticky biochemical waste (tested on penicillin production sludge).
Variable-speed drive (0-20 RPM) lets you adjust pressure for different viscosities—from thin fermentation broth to thick polymer sludge.
Large 2m-long filter screen (0.5mm pores) with anti-clogging surface treatment, reducing screen replacements by 50% versus standard presses.
PLC-based control panel with remote monitoring via Ethernet—track solids content, motor torque, and water flow from your office.
Automatic overload protection: Stops the screw and sounds an alarm if solids buildup exceeds safe levels, preventing motor damage.
Pharmaceutical Plants: Handles sludges from API production, fermentation tanks, and wastewater with residual solvents.
Biotech Facilities: Dewaters cell culture waste, plasmid DNA production sludge, and other high-value biological residues.
Chemical Processing: Effective for polymer sludge, catalyst residues, and sludges with heavy metal chelates.
Industry Expertise: The only press certified for biochemical wastewater by the International Society of Pharmaceutical Engineering (ISPE).
Downtime Reduction: Advanced materials and self-monitoring features cut maintenance time by 40% compared to generic industrial presses.
Custom Solutions: We offer optional heated jackets for low-temperature environments and explosion-proof motors for hazardous zones.
Structure
BOEEP volute screw press dehydrator is composed of screw body, driving device, filtrate receiver, mixing system and frame. There are 3 parts constitutes the main body of volute screw press dehydrator. They are fixed ring, moveable ring and the screw shaft which runs through the main body. The former part undertakes the task of concentration and the latter part assumes the task of dehydration. It can thicken and dewater sludge in one chamber and has taken place of the traditional filter clothes and centrifugal filtration method for its distinctive function.
Working Principle
How does the volute screw press dehydrator work? Sludge will be transported to the mixing tank by sludge feed pump, meanwhile, the prepared polymer has been added to the mixing tank quantitatively by the polymer feed pump. Mixing motor drives the whole mixing system to make the sludge and polymer fully mixed and then flocs will be produced. When the liquid level arrives at the superior level of the liquid level sensor, the liquid level sensor gets the signal to make the motor of screw body operates, then begins to press the sludge which has flows into the screw body. Sludge will be transported to the outlet step by step by the effect of screw shaft; filtrate will flow out by the space of fixed annular plates and moveable annular plates.
