SUS304 Screw Press Dewatering Machine IP55 Protection Grade 40-1500L

Description

Dewatering screw press is used for efficient thickening and dewatering of sludge waters. Sludge waters are water, containing certain amount of suspended solids, these can be product of waste water treatment, food proccessing industry, chemical industry and other branches of human activity. Our dewatering screw press, which serves to thicken sludge water to 20% dry-matter content on municipal sludges and more for mineral/industrial sludges, can provide efficient desludging. In terms of quality, this equipment surpasses traditional sedimentation sludge removal and other technologies.

This dewatering/thickening screw press has been designed to be used primarily in wastewater treatment plants, but can also be used for thickening both industrial water and wastewater in food-processing operations

If a dewatering press is already incorporated into the new WWTP design, costs related to the construction of sedimentation tanks are eliminated as this equipment can also be used for thickening secondary sludge directly from activation.

Principle:

Gravity zone: When the shaft is driven by the screw, moving rings around the shaft move up and down relatively. Most water is pressed out from the thickening zone and fall down to the filtrate tank for gravity. Pressure zone: The thickened sludge moves forward continuously from the gravity zone towards the pressure zone. With the pitch of the screw shaft thread getting narrower and narrower, the pressure in the filter chamber increases higher and higher. In addition to the pressure generated by the back-pressure plate, the sludge is greatly pressed and dryer sludge cakes produce.

Applications

Dewatering screw press could be used in the treatment of industrial wastewater, surface water, reused water, drinking water plant and Municipal Wastewater Treatment Plant.
