This week GN solids control shipped one batch of waste sludge dewatering equipments to Environmental company, including: Dewatering Centrifuge, Screw Press Dewatering Machine, and Chemical Dosing Unit.
The dewatering centrifuge package including one unit of dewatering centrifuge, 1 set of mud tank to collect the clean fluids, one unit of submersible slurry pump as centrifuge feeding pump, 1 unit of mud agitator for agitating the slurry. The chemical doing unit will feed the prepared chemicals to the dewatering centrifuge and well mixed in the centrifuge feed tube, then the mixture chemicals and slurry will be enter into the dewatering centrifuge, under the working of G force, the light fluids are discharged from fluids discharge port, the solids are discharged from solids discharge port, both of the fluids distribution port and solids discharge port are protected by tungsten carbide alloy, and it is interchangeable once damaged.
The Screw Press Dewatering Machine is a sludge extrusion dewatering equipment. The working principal is by the strong squeezing force generated by the change of screw diameter and screw pitch, and the tiny gap between the floating ring and the fixed ring, to realize solid-liquid separation. It can be widely used for dewatering the industrial waste sludge, oil waste sludge and other sewage treatment projects. It can work continuously and automatically, it will not block frequently. It is energy saving and environmental friendly solution, compact design with small footprint, only need a small space to locate it. Just compared with dewatering centrifuge, its treating capacity is not so high. Especially for oil sludge treatment, decanter centrifuge treatment result is the best. But screw press is with lower energy consumption and a little lower cost. Compared with screw press and decanter centrifuge, filter press investment is very high, and efficiency is lower, discharged solids is drier.
