Service Case

Our water treatment decanter centrifuges are excellent in practical applications, and these customer cases are all from our real project applications around the world. Through these cases, you can better understand our products and choose the centrifuge that best suits your needs and help you solve your water treatment challenges.

New Materials Company Uses Decanter for Sewage Purification

The owner of the project is a new material technology company. It is a sewage treatment project. The project uses ZK 550 two-phase centrifuge skid-mounted system. The raw materials include domestic sewage, mixed sewage with sediment and mixed sewage with carbon powder. ZK centrifuge played a vital role in the sewage treatment project. It purified the sewage by separating the solid particles and the liquid part in the sewage, and realized the recycling and reuse of water at the same time.

ZK Decanter Solves Steel Rolling Wastewater Challenge

ZK centrifuge for water treatment successfully solved the problem of wastewater treatment in a steel company. After being treated with a centrifuge, the solid content in the waste water is significantly reduced, the moisture content of the slag after treatment does not exceed 23%, and the solid recovery rate is as high as 95%. Compared with the previous method of extracting the upper layer of wastewater and cleaning the pool with an excavator, the centrifuge separation process reduces the labor intensity of the operator and greatly improves the production efficiency. And it provides an efficient and sustainable waste water treatment scheme for iron and steel production enterprises while reducing production costs.
