Seasonal Fouling Was Disrupting Operations—Until This Power Plant Made a Change
A U.S. power plant relied on surface water for boiler make-up, but every spring, rising temperatures triggered an influx of biological growth and suspended solids. This led to accelerated organic fouling in their RO system, forcing them into increased chemical cleanings and annual membrane replacements, far more often than expected for a conventional RO system.
Concerned about unplanned downtime and escalating maintenance, the plant installed ZwitterCo’s advanced zwitterionic RO membranes alongside their existing system to compare performance and fouling resistance.
Designed to repel organics and tackle surface water challenges such as biological growth and suspended solids, ZwitterCo membranes offered a resilient solution. Even under a severe coagulant overdose that severely impacted feedwater quality— forcing conventional membranes into frequent cleanings and performance decline—ZwitterCo’s membranes resisted fouling, maintained stable performance, and kept operations running smoothly.
The Impact:
- 70% Reduction in downtime from membrane cleaning
- Only 2 cleanings in a year, compared to 7 for conventional membranes
- Consistently high permeate flow and extended membrane life
