A landfill in Europe faced constant disruptions in its leachate treatment process due to severe organic fouling. These issues led to excessive chemical cleaning, frequent membrane replacements every two months, and prolonged downtime, driving up both operational complexity and cost.

The facility installed ZwitterCo’s advanced RO membranes, designed specifically to resist complex organic fouling typical in landfill leachate. The membranes integrated smoothly into existing equipment without interrupting operations, quickly demonstrating strong fouling resistance and greatly simplifying maintenance.

Impactful Results

✅ 460+ additional hours of system uptime per year, thanks to fewer cleanings and simplified operations

✅ 3x increase in membrane lifespan, operating for over 6 months compared to ~2 months with standard RO membranes

✅ Nearly 50% reduction in total annual cleaning costs, including savings on chemicals, labor, downtime, and replacement membranes

✅ Significant reduction in cleaning water consumption, saving over 82,000 gallons of water annually
