Screw Press/Volute Dewatering Press, Solid Liquid Separation Equipment
The volute dewatering press uses low-speed screw extrusion technology with lower electrical power consumption and it has function to concentrate the sludge, therefore, no concentration and storage unit is needed and the space of the whole sewage treatment plant and the costs can be reduced. The volute dewatering press is widely used in civil sewage treatment engineering and wastewater treatment system in petrochemical, light industry, chemical fiber, paper making, pharmaceutical and leather industries.
Characteristics
The models of volute dewatering press are various, so you can find the most suitable model according to your needs. Equipped with an electric cabinet and sludge flocculation mixing tank, it’s highly compatible with supporting equipment. The main body of the dewatering press can be self-cleaned, so it doesn’t need too much water to prevent sludge clogging.

Details
The main body of the volute dewatering press is a filter device composed of a fixed ring and a moving ring overlapping each other and a spiral shaft running through it. The front part is a concentration device and the rear part is the dehydrating device.
The gap between the fixed ring and the moving ring and the pitch of the screw shaft are gradually getting smaller from the concentration device to the dehydrating device.
The rotation of the screw shaft not only pushes the sludge from the concentration device to the dehydrating device, but also drives the moving ring to clean the filter seams preventing clogging.
Electric cabinet
The electric cabinet is automatically controlled, which can realize continuous unattended operation from sludge transportation, drug injection, concentration and dehydration to filter cake discharge, reducing the labor costs.
