SSD Decanter Centrifuge Is Special Designed For Sewage Sludge Or Sediment Sludge Treatment. The Sediment Sludge Can Mainly From Municipal Sewage Sludge And Various Industry Sewage Sludge.
Waterworks is very important to every city and huge amount of water is requested every day. To treat the waterworks sludge in efficient way is helpful for sustainable development of water resources and better cost control. SSD Series Decanter Centrifuge is special designed for waterworks sludge; and we can offer turnkey solution to reduce the sludge volume, reduce the sludge transportation cost and recycle the value water resources. The final sludge cakes can be used for landfill or construction application.
The sewage living waste water can settle down in the big pond of sewage treat plant, then the upper clean liquid can be treated by filtration unit, OS reverse osmosis technology and Sterilization & Deodorizing equipment to further clean the water for recycle and reuse. The sediment in the sewage pond contains high content of water can feed to decanter centrifuge for dewatering application. After dewatering, the liquid phase can be treated again by the same technology including filtration, reverse osmosis, sterilization and deodorization. The sludge cakes discharge from decanter centrifuge with very less water content can be easily storage and transportation. Normally, the sludge cakes can be disposed to agriculture area or can be used for construction application depends on the regulations of local environment department.

SSD Series Decanter Centrifuge Application On Various Industry Sewage Sludge
Industry waste water is generated in the production processing or cleaning process. In the past, the waste water will be poured to waste water pit / waste pond for storage; this treatment require large space of waste water pit and not accepted by government regulations as the bigger footprint and environment pollution. MJ MACH SSD Series Decanter centrifuge can be best choice to perform the separation and recovery process, reduce the waste water pond size and reduce the construction cost. Meanwhile, the recovered water can be reused for the production process. SSD Series Decanter Centrifuge can be applied to many kinds of industry waste water as follows:
Sand washing waste water separation and recovery
Gravel washing waste water separation and recovery
Mine washing waste water separation and conveying
Special stone washing waste water separation and conveying
Paint sludge waste sludge separation and conveying
Iron and steel works sludge separation and conveying
Paper mill waste sludge separation and conveying
Chemical washing waste separation and recovery
SSD Series Decanter Centrifuge Application On Mining Industry
Decanter separation process is very important for each corner of mining industry, including Ore and minerals. The most important technical point is how to avoid or reduce the wearing on scroll impellers for mining industry; with our patent design on the feeding port and special hard facing technology, we can minimize the wearing and get much longer effective lifetime than our competitors.
