- Reduced Cleaning Frequency:The TFN membrane delivers outstanding anti-fouling performance, significantly reducing the presence of microorganisms and inorganic pollutants. This leads to a lower cleaning frequency.
- Wide Cleaning pH(1-13) Range:With a broad cleaning pH range and exceptional chemical tolerance, it offers the most effective cleaning performance, robustness, and durability.
Key Applications:
Ideal for softening, producing pure water, and water reuse in
industries such as pharmaceuticals, electronics, power generation, petrochemicals, refineries, food & beverage, and municipal services, among others.
A common challenge with RO membrane elements is fouling. While fouling doesn't alter the structure of RO membrane elements, the accumulation on the membrane surface significantly hampers performance.
Proshare Extreme Anti-Fouling reverse osmosis (RO) technology effectively prevents fouling by utilizing a proprietary hydrophilic coating on the membrane surface. This ensures long-term stable operation, reduces cleaning frequency, and ultimately lowers operational expenses (OPEX) at the water treatment facility.
Proshare Extreme Anti- Fouling membrane is ideal for your needs in treating urban sewage water for industrial applications.
