Landfill Leachate Treatment: High Recovery and ZLD Results
May 22nd 2019
Saltworks Technologies Inc. (Saltworks) completed an end-to-end zero liquid discharge (ZLD) and zero air emission off-site pilot to treat concentrated reverse osmosis leachate brine from a municipal landfill in China.
The site presently treats raw leachate with biological treatment, conventional RO, and disc tube RO (DTRO) systems. The DTRO brine reject is sent back to the landfill. However, the TDS of leachate is getting higher. The client is preparing for new regulations that could forbid this practice. The project objective was therefore to eliminate the wastewater volume by producing both clean water and solids at the lowest total cost of ownership.

Treating Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) Contaminated Wastewater and Landfill Leachate
PFAS chemicals are often referred to as “forever chemicals” since they do not naturally degrade. PFAS are detected in wastewaters and landfill leachate due to their widespread uses in consumer and industrial products. They have made their way into some water supplies.
Reverse osmosis (RO) is the best available technology to treat landfill leachate for surface discharge. Possible trace volatile organic compounds (VOCs) and ammonia emerging in the RO permeate can be removed with a polishing step to meet the highest discharge standards.
Heavy industry, manufacturing, and natural resource-based industries often use large volumes of water and generate wastewaters requiring treatment. Saltworks designs, builds, and operates industrial wastewater treatment plants with modern membrane, chemical, and thermal technologies that economically and reliably treat tough industrial wastewaters.
