The volume and composition of the landfill leachate varies with the season and climate of different refuse landfills. However, their common characteristics include multiple varieties, high content of pollutants, high degree of color, as well as high concentration of both COD and ammonia. Therefore, landfill leachate is a kind of wastewater that is not easily treated with traditional methods.

By cooperating with an environmental protection company, our company has carried out the experimental research and technology development for a solution to the problems associated with leachate sewage treatment. The Haining landfill leachate treatment project is an outstanding case. Using a belt filter press made by HaiBar, the solid content can reach over 22% after compression and dehydration. This machine has been highly praised by our customers.
