Landfill leachate is a wastewater with complex water quality, high organic matter and high heavy metal pollution. Direct disposal can cause serious environmental risks if left untreated.
Our customers demand stable water quality that meets stringent environmental regulations. Typical characteristics of these applications are the removal of high concentrations of organic pollutants (Bod/cod) and total suspended solids (TSS).
Although typical treatment processes for such wastewater require multiple processing steps, high performance membrane technology is the core process for meeting stringent emission regulations.
According to the amount of water, water quality and discharge requirements. Our application engineers can recommend the best configuration and membrane products to meet your needs. For the upgrade of existing membrane systems, we can help you optimize the overall output of the system and the performance of the membrane products.

Two-stage STRO process
Different regions, different seasons, different levels of garbage sorting, will affect the concentration of landfill leachate pollutants
