QDEVU® sludge dewatering machine is designed with a compact structure and consists of an electric control cabinet, flocculation tank, and dehydrator body. It is constructed with high-quality stainless steel, which effectively prevents the accumulation of oil and dirt. Moreover, the machine utilizes a unique dewatering principle that enables it to handle various concentrations of sludge without requiring any dilution.
QDEVU Screw Press Sludge Dewatering Machine is designed for efficient thickening and dewatering of liquid sludges that emanate from wastewater treatment processes. Typical applications for wastewater treatment plants include dewatering of thickened or unthickened waste activated sludge (WAS), digested sludge from aerobic or anaerobic processes, and dissolved air flotation (DAF) sludges.
The screw press sludge dewatering machine uses the automatic renewal filter cake filtration technology to replace the traditional filter screen filtration to ensure the continuous and stable sludge water separation effect of the dehydrator. Through the strong extrusion pressure generated by the change of screw diameter and pitch, as well as the small gap between the swimming ring and the fixed ring, it realizes the extrusion dehydration of sludge. It is a new type of solid-liquid separation equipment.
WORKING PRINCIPLE
The wastewater is pushed into the dewatering machine.The sludge will move to the sludge cake outlet under the pressure of the helical aixs blades. Becuse the gap among the helical blades become narrower,so the sludge bear heavier pressure and began to dewatering under the pressure. The water comes out from the space between fixed and moving plates.

STANDARD SPECIFICATIONS
Notes:
1 Depending on sludge type, polymer type and polymer dose, up to 20% additional throughput may be possible.
2 Depending on sludge type and polymer type, the typical polymer consumption for feed sludge concentration 2 - 5 g/L is 4-8 kg/tonne dry solids processed, and for feed sludge concentration 5 - 50 g/L is 10-25 kg/tonne dry solids processed.
