An Economical & Reliable Solution for Landfill Leachate
A Compact Solution for Leachate
Landfill leachate is generated when rainwater and waste fluids collect at the bottom of a landfill. Leachate must be managed through careful treatment and disposal to prevent groundwater or surface water contamination.
ZwitterCo provides a core technology within the world’s leading integrated solutions for treating landfill leachate.
Our membranes extract tough-to-treat compounds from leachate so that connected desalination and thermal treatment technologies operate efficiently, making it affordable to produce clean and reusable water, or to discharge safely to the environment.
Benefits of ZwitterCo’s Superfiltration (SF) Membranes
Reduce offsite hauling
Concentrating leachate with membranes can reduce hauling volumes by 80% or more
Reduce evaporator needs
Concentrating leachate prior to evaporation can reduce evaporator footprint and energy consumption
Improve sustainability
Reusing water for dust control and reducing hauling can decrease carbon intensity score
Reliable and economical treatment
Our membranes maintain consistent performance in leachate streams with notoriously inconsistent quality
Operate reverse osmosis at high recovery
Superfiltration is the tightest available pretreatment for reverse osmosis, leading to longer membrane life
ZwitterCo’s Unique Technology
Our patented superfiltration membrane is ideal as a pretreatment to reverse osmosis or thermal treatment technologies by removing problematic foulants such as TSS, COD, and oil and grease.
Unlike biological systems, which are prone to upsets from inconsistent leachate quality and variable flow rates, SF maintains consistent performance.
