The advantages of sludge dewatering screw press

May 08, 2018

Sludge dewatering screw press is a new type of solid-liquid separation equipment. Compared with traditional equipment, the sludge dewatering screw press is different from the traditional equipment. It uses cleverly applied automatic filter cake filtration technology instead of traditional filter screen filtration, and the moving ring and fixed Small gaps between the rings enable squeezed dewatering of the sludge.


It can be seen that the sludge dewatering screw press is a typical screw press dewatering machine, which can be widely used in the dewatering of municipal sewage, food, beverage, slaughter and breeding, printing and dyeing, petrochemical, paper, leather, pharmaceutical and other industries. With its own unique dehydration principle, the equipment is suitable for high and low concentrations of sludge, especially oily sludge.


Sludge dewatering screw press adopts a unique dynamic and static ring filter joint structure, which makes the equipment not easy to be blocked, and does not need to be cleaned in large quantities to prevent clogging of the filter joint, completely reducing the flushing water consumption, reducing the burden of internal circulation, and solving the traditional dehydration. The troubles caused by equipment jams to the company.


Sludge dewatering screw press adopts automatic control to extract sludge, inject chemical liquid and discharge sludge cake. Through electronic control cabinet, it is linked with foaming machine, mud pump and dosing pump, without personnel operation equipment. , The operation will not be blocked, filter belt deviation or other effects on the safety of the process, daily maintenance is simple, in the true sense of sludge dehydration continuous automatic operation.


The integrated design sludge dewatering screw press greatly saves operating costs; and its low-speed screw extrusion technology enables a significant reduction in power consumption; plus the device does not block, flushing water is greatly reduced; and can be 24 hours No one runs automatically, and labor costs are greatly reduced. Therefore, the sludge dewatering screw press has become a new type of energy-saving and environmental-friendly equipment that meets the national policy.


Since the sludge dewatering screw press is directly mechanically dewatered without the need for a large body such as a roller, the machine is designed to be extremely lightweight; almost all of the body is made of stainless steel, and the replacement parts are only the screw shaft and the traveling ring, which has a long service life. Durable.


The sludge dewatering screw press itself has the function of sludge concentration, directly treating the aerobic sludge in the aeration tank, and does not require a concentration and storage unit, thereby reducing the overall land occupation space and construction cost of the sewage treatment facility. Sludge in the sludge dewatering screw press can be dehydrated under aerobic conditions, without the release of sludge from the sludge in the conventional sludge concentration tank or storage tank under anoxic or anaerobic conditions, thereby improving the entire sewage treatment system Phosphorus removal function.
