QDEVU® QDLX131 Screw Press Sludge Dewatering Machine

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 PROCESS

• The sludge is transported to the inlet by sludge conveyor.
• The sludge are transported to the flocculation tank through metering tank, and adequately mixed by the mixer.
• After big flocs are formed, the sewage is transported to the screw press.
• Flocs moves from the concentration zone to the dewatering zone by gravity.
• Gaps between moving rings and fixed rings narrows, and the pressure of the end plate increases dewatering and finally discharge the sludge cake.

FEATURE

• Small Foot Print.Can be installed in places where placement would not be possible with other technology .
• No Blocking.Due to the moving of the fixed rings and moving rings self -cleaning .The ubiquitous clogging is avoided .Handing oily sludge without trouble while separating the water from the sludge easily . Above all , no need large quantiry of flushing water and no odor ,no secondary pollution during the sludge dewatering process .
• Fully Automatic Control.Sludge Dewatering Device equipped without device like filter clothes or filter pore that easy blocked .Operation so easily and can be set to operate automatically via the eletric control cabinet .
• Operation Cost: Integrated design, compact structure, greatly saving operation cost; 24-hour full-automatic unmanned operation, greatly reducing labor costs; The equipment covers a small area and reduces the civil engineering investment
• Light and Durable: The body is almost entirely made of stainless steel, and the replacement parts are only the screw shaft and the traveling ring, which has a long service life and is durable

APPLICATION

• Municipal Sewage
• Slaughter House
• Metallurgical  Industry Wastewater
• Oily Wastewater
• Printing  & Dyeing Sewage
• Metal-Processing Sewage
• Mining Stone Wastewater
• Electronic Sewage

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.
