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 main part of the dehydrator is a filter device that a screw runs through the stacked fixed rings and moving ring.  The small gaps between fixed rings and moving ring can filter the sludge, and the lumen between screw and rings is filled with polymer grains. The moving ring transfers the sludge to the end of the machine with pressure and extrudes sludge cakes.   Layers of the spacers, which are Fixed and Moving Rings, are secured in place by a tie rod. The inner diameters of the Moving Rings are slightly smaller than the outer diameter of the screw and their rings. Mobilized by the screw, it continuously cleans the sludge out of the gaps, therefore, preventing clogging.

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, it do the circular motion with the screw axis to prevent clogging, to ensure the continuous operation

Sludge is firstly fed into the Flow Control Tank and then flows down into the Flocculation Tank, where polymer coagulant is added. From there, the flocculated sludge overflows into the dewatering drum where it is filtered and compressed. The entire operation sequence, including sludge feed control, polymer makeup, dosing and sludge cake discharge are controlled by the built-in timer and sensors of the PLC. The Sludge Dewatering Press offers a completely operational, skid mounted and self-contained system which can include:  Screw Press, PLC Controls, Sludge Pumps, Back Wash System , Flocculation System, Polymer Dosing Unit, Sludge Cake Conveyor.

OP solid liquid separator adopt a unique separation technology. It’s brand new dewatering technology, which enables self-cleaning automatically for the filter gaps during sludge thickening and dewatering. Meanwhile this machine has stable and constant capacity without depending on high pressure backwash water to prevent clog. This self-cleaning system enables OP sludge dewatering press to be a good machine for oily and grease sludge.

The thickening and dewatering zone is composed of stainless steel screen bars and plate , they are interlaced with each other. The plates are all penetrate through the gaps between screen bars ( ≤ 1mm ). During operation, the plates rotate slowly to transport sludge forward and the filtrate flows down through the gaps. During rotation, the plates are also cleaning the gaps between screen bars, so there is no chance for clogging.

Integrated sewage sludge dewatering is a new sludge treatment product designed for some special occasions, such as complicated environment, unstable sludge volume, temporary, etc.

Automatic dosing machine is a continuous polymer makeup and dosing equipment. The equipment can mix the polymer fully with high efficiency, and then the homogeneous activated polymer can be ready for further treatment. Widely applied as the supporting equipment of sludge dewatering equipment in municipal wastewater, slaughtering, chemical plant and etc.

High quality daf wastewater treatment plant with price is a water treatment process that clarifieswastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms tiny bubbles which adhere to the suspended matter causing the suspended matter to float to the surface of the water where it may then be removed by a skimming device. Dissolved air flotation is very widely used in treating the industrial wastewater effluents from oil  refineries, petrochemicaland chemical plants, natural gas processing plants, paper mills, general water treatment and similar industrial facilities.
