GN Separation Equipment Manufacturer

Recently, GN completed the manufacture of a batch of sludge dewatering equipment, which will be shipped to the work site of overseas customer soon. This order includes sludge inclined plate clarifier device and a batch of sludge dewatering decanter centrifuges.

The sludge inclined plate clarifier is a gravity sedimentation device, which increases the sedimentation of suspended particles in the sludge by adding multiple groups of inclined plates in the metal tank. During the process of sludge flowing from the inlet to the outlet of the equipment, the suspended particles will settle under the action of gravity. When the fluid meets the inclined plate group, the suspended particles will impact on the inclined plate, then move down along the inclined plate, and finally settle to the V-shaped groove at the bottom of the equipment, and then be transported to the slag discharge port through the screw installed at the bottom. The liquid discharged from the outlet of the inclined plate clarifier will be clearer than the sludge at the inlet. With the use of flocculation dosing unit, the inclined plate clarifier can play a better role in sludge sedimentation and concentration.

The sludge accumulated at the bottom of the inclined plate clarifier has relatively high humidity and cannot meet the requirements of storage and transportation. If a sludge dewatering decanter centrifuge is installed behind the inclined plate clarifier, the sludge can be further dewatered. In fact, in some small sewage treatment plants, due to the limited site, the inclined plate clarifier can greatly improve the sludge sedimentation area and play the role of sludge sedimentation pit. GN sludge dewatering decanter centrifuge performs solid-liquid separation on the sludge passing through it through high-speed centrifugation. Under the action of flocculant, it can capture fine particles and make the discharged liquid phase clearer.

In some sludge dewatering works, the cost of the inclined plate clarifier is low, which can play the role of preliminary sludge concentration and reducing land occupation, and can play the role of sludge purification to a certain extent; If there are higher requirements for sludge dewatering, it is often necessary to install more efficient sludge dewatering equipment such as filter press, screw press or sludge dewatering decanter centrifuge behind it.
