- Reduce Cleaning Frequency by Up to 50%
:The outstanding anti-fouling performance of the TFN membrane significantly minimizes microorganism and inorganic pollutant accumulation, leading to a drastically reduced cleaning frequency.
- Reduce Operational Expenditure (OPEX) by 30%-50%
The membrane offers exceptional cleaning efficiency, robustness, and durability, owing to its extensive cleaning pH range and high chemical tolerance.
Key Applications:
Efficient softening, production of pure water, and water reuse across various industries, including
pharmaceutical, electronics, power, petrochemical, refinery, food & beverage, and municipal sectors, among others.
A prevalent issue with RO membrane elements is fouling. While fouling may not alter the structure of RO membrane elements, the buildup of foulants on the membrane surface can drastically impact its performance.
Proshare Extreme Anti-Fouling reverse osmosis (RO) combats fouling by employing an exclusive hydrophilic coating on the membrane surface, ensuring long-term stable operation. By reducing fouling, the membrane decreases cleaning frequency, ultimately contributing to lowered OPEX at the water treatment facility.
Proshare Extreme Anti- Fouling is perfectly suited for the treatment of urban sewage water for industrial applications.
