Leachate from waste disposal operations
What is it?

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.

How we treat leachate from waste disposal operations:

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:

  • Filtration - Water passes through sand, multimedia or other filter media to remove fine particles.
  • Chemical Precipitation - Chemicals are added to support the formation of insoluble precipitates to help remove remaining contaminants.
  • Sludge Treatment and Disposal - Sludge created from the primary and secondary treatment processes is treated separately.The treated sludge can be used for beneficial purposes such as land application or disposed of in an environmentally responsible manner.

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.
