Durable Screw Press Dewatering Machine Automatic Operation Heavy Duty

Durable Screw Press Dewatering Machine Automatic Operation Heavy Duty

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:

Thickening 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.

Dewatering zone: The thickened sludge moves forward continuously from the gravity zone towards the dewatering 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 end plate, the sludge is greatly pressed and dryer sludge cakes produce.

Details:

Thickening tank: In the mixing tank, can thicken the sludge with a concentration less than 10000mg/L first.

Mixing reducer:

• Using first-class reducers,Nord or SEW are optional according to your actual requirements.
• To ensure the sludge and polumer fully mixed.
• Excellent performance to keep the long lifespan.
• Liquid level adjusting device is assembled to adjust sludge inletting amount.

Screw Body

• Mainly composed of fixed annular plates and moveable annular plates.
• Adopting Wearable material to keep the service life longer.
• Thickening and dewatering of the sludge can be finished in one zone

Electric Control Panel

• Frequency converting controls dewatering body.
• Controls poly mixing device.
• Realize the switch of automatic operation and manual operation.

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.
