ZK Decanter Centrifuge for Municipal Sewage Treatment Solutions
ZK urban sewage centrifuge is the most economical, environmentally friendly, and most efficient separation and clarification equipment for solid-liquid separation of urban domestic sewage and sludge dehydration treatment. ZK SEPARATION has more than 20 years of experience in sludge dewatering and thickening. We understand the special requirements and technological processes of sewage treatment plants and the water industry. Our urban sludge centrifuges are highly adaptable to sludge. In low-concentration treatment, no thicken is required to achieve the dehydration function and meet the integrated thicken and dewatering process requirements. The unique structure, advanced control system, and standardized design of the ZK Separate Decanter Centrifuge significantly reduce labor costs in the later period and save the municipal sewage treatment plant's cost.
