Printing And Dying Wastewater Treatment 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

Screw type press is composed of screw body, driving device, filtrate receiver, mixing system and frame. When the volute press dewatering operation, sludge will be transported to the mixing tank by sludge feed pump, at the same time, the solid polymer has been added to the mixing tank quantitatively by the polymer feed pump. Mixing motor drives the whole mixing system to make the sludge and polymer fully mixed and then flocs will be produced. When the liquid level arrives at the superior level of the liquid level sensor, the liquid level sensor gets the signal to make the motor of screw body operates, then begins to press the sludge which has flows into the screw body. Sludge will be transported to the outlet step by step by the effect of screw shaft; filtrate will flow out by the space of fixed rings and moveable rings.

FEATURE

• Low energy consumption.
• Minimal water consumption.
• Minimal noise.
• Low polymer consumption.
• No need for proceeding sludge thickening.
• Suitable for any type of sludge even suitable for dewatering oil/grease rich sludge.
• Minimal maintenance and operational cost.
• Capable for working 24/7.

ADVANTAGES

• Application: widely used in municipal sewage, food, beverage, animal husbandry, printing and dyeing, petrochemical, paper, leather, pharmaceutical and other industries
• No blocking: the unique dynamic and static ring filter slot structure makes the equipment not easy to block
• Control: automatic control is adopted, no personnel are required to operate the equipment, and 24-hour continuous unmanned operation is possible
• 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

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.
