Delivers unmatched cleaning performance, resilience, and longevity due to its broad cleaning pH range and chemical tolerance.
Primary Applications:
Water softening, producing pure water, and water reuse in
pharmaceutical, electronics, power, petrochemical, refinery, food & beverage, municipal sectors, etc.
A common issue with RO membrane elements is fouling. While fouling doesn't alter the structure of RO membrane elements, the deposits on the membrane surface can significantly diminish its performance.
Proshare Extreme Anti-Fouling reverse osmosis (RO) prevents fouling by utilizing an exclusive hydrophilic coating on the membrane surface, ensuring long-term stable operation. By preventing fouling, the reduced cleaning frequency contributes to lower OPEX at water treatment facilities.
Proshare Extreme Anti- Fouling meets your requirements for treating urban sewage water in industrial applications.
