Leachate is the liquid that drains or 'leaches' from a landfill. It may contain pollutants and contaminants derived from the waste in the landfill. In Australia, the management and disposal of leachate are subject to environmental regulations and guidelines set by federal, state, and local authorities. Generally, leachate is considered a potentially hazardous waste due to its contaminants, and its treatment and disposal are regulated to prevent environmental harm.
Preliminary Treatment - We remove large, easily separable solids through physical processes such as screening and sedimentation. Preliminary treatment helps protect downstream treatment processes from blocking and damage.
Primary Treatment - The removal of settleable organic and inorganic solids through sedimentation. In this treatment, wastewater flows into secondary tanks and transferred to the next treatment stage.
Secondary Treatment - An additional step to further clean the treated water, removing remaining contaminants to achieve higher water quality standards. Secondary treatment methods may include:
The selection and sequence of treatment processes depend on the characteristics of the industrial wastewater, local regulatory requirements, and the desired quality of the treated water. We'll always work closely with our customers to determine the best course of treatment for their waste materials.
