A landfill in southwestern Europe was facing persistent operational and financial stress while managing high-strength leachate. The facility’s first-pass RO system required frequent cleanings with costly formulated chemicals, driving up costs and slowing operations.

To fix this, the site installed ZwitterCo’s fouling-resistant RO membranes in the first pass of their system. Designed for tough leachate streams, these membranes were easily implemented and have delivered reliable, stable performance over four months of operation.

So far, the pilot has already demonstrated:

💧 Over 90% reduction in chemical cleaning costs through simplified cleaning

💧 Less downtime and full recovery after each clean

💧 Improved normalized flow and decreasing operating pressures, with continued sustainable performance
