At present, landfill leachate is pre-treated at the leachate treatment facility and then discharged to the sewage treatment facility for further treatment. However, existing facilities cannot remove colored non-biodegradable organics present in landfill leachate. To address this issue, HKPC has actively developed an innovative composite chemical precipitation process that utilised its own research and development of formulated chemicals to provide an efficient treatment process that significantly removes colored non-biodegradable organic matter from the landfill leachates.
