Stainless Plate And Frame Filter Press for sludge thickening and dehydrator in effluent treatment plant

Stainless MDS screw press for sludge thickening and dehydrator in effluent treatment plant

Direct dewatering the oxidation ditch

The Multi-Disk Screw Press belongs to the screw press, it's clog-free and can reduce the sedimentation tank and sludge thickening tank, saving the cost of sewage plant construction. MDS using screw and the moving rings to clean itself as clog-free structure, and controlled by the PLC automatically, it's a new technology that can replace the traditional filter press like belt press and frame press, the screw speed is very low, so it cost low power and water consumption in contrast to the centrifuge, it is a cutting edge sludge dewatering machine.

The Sludge Dewatering Press is an enclosed high performance sludge dewatering system. It utilizes a central screw auger and a slowly oscillating multi-disk filter to gradually increase pressure on flocculated sludge to produce an exceptionally dry sludge cake. With electrical, water and polymer usage, and high capture rates the system is very cost effective.
The Sludge Dewatering Press can be provided with all equipment required for dewatering included and factory mounted, piped and wired on a single stainless steel skid. This equipment includes the sludge pump, wash water pump, polymer dosing system and control panel. The system features fully automated one pushbutton startup and shutdown. Once started up the system can run unattended and can be set to shutdown automatically with no operator intervention.

Application

• Sewage and waste water treatment plants of municipal water
• Waste water treatment plant in agricultrual & fishery community
• Industrial waste water treatment plants
• Effluent treatment plant in food & beverage production plants
• Dairy farming / meat processing plants
• Chemicals manufacturing plants
• Machinery manufacturing plants
• Laundry wastewater treatment
• Paper & pulp, building material manufacturing, oilfield associated waste water containing crude oil mining.

Technical introduction

The volute is structured with a filter element that consists of two type rings: a fixed ring and a moving ring; and a screw that thrusts the filter element and transfers and pressurizes the sludge. The gaps between the rings and the screw pitch are designed to gradually get narrower towards the direction of sludge cake outlet and inner pressure of the filter element increases due to the volume compression effect, which thicknens and dewaters the sludge.

Features:

• The dewatering body is formed by a screw axis with fixing and moving plates overlapping, as the inner diameter of screw axis is larger than the moving plate, the moving plate do the circular motion with the screw axis to prevent clogging, to ensure the continuous operation
• Municipal wastewater, papermaking wastewater, chemical waste water, food and beverage processing waste water, industrial wastewater, papermaking wastewater, pharmaceutical wastewater, oil processing and mining wastewater, etc.
• Comparing with the traditional belt, plate& frame and centrifugal machine,volute sludge dewatering machine adopts integrated design of dehydration ontology, flocculation mixing tank and electric control device, convenient installation , small area cover, strong compatibility with ancillary equipment, greatly reduce design and the construction cost, at the same time, no need to undertake civil construction as its exquisite design.
• Can realise 24 hours automatic unmanned operation by PLC remote control , reduce the operating personnel employment and maintenance costs. At the same time, due to the exquisite design, easy operation, it is easy to learn as no special knowledge and skilled technical complex requirements.
• Main body can self-cleaning due to the special structure, threr is no need to use a lot of water for cleaning to prevent clogging. Compared with the same capacity of dewatering machine, screw rinse water consumption is only 1% of belt . The rotation speed of screw shaft is 2-5 turn/min , low power consumption. Power consumption is only 5% of the centrifuge, at the same time, no noise during operation as slow rotation speed and intermittent flush.
