- Reduces Cleaning Frequency by Up to 50%
:The TFN membrane's exceptional anti-fouling capabilities significantly diminish microbial and inorganic contaminants, leading to reduced cleaning frequency.
- Lowers OPEX by 30%-50%
Delivers highly effective cleaning performance, robustness, and durability thanks to its extensive cleaning pH range and exceptional chemical tolerance.
Key Applications:
Ideal for softening, pure water production, and water reuse across diverse industries such as
pharmaceutical, electronics, power, petrochemical, refinery, food & beverage, municipal, etc.
A common challenge with RO membrane elements is fouling. While fouling doesn't alter the membrane structure, the deposition of foulants on the surface can significantly impair its performance.
Proshare Extreme Anti-Fouling reverse osmosis (RO) effectively combats fouling by employing a unique hydrophilic coating on the membrane surface, ensuring long-term stable operations. Prevention of fouling leads to decreased cleaning frequency and ultimately reduces OPEX in water treatment facilities.
Proshare Extreme Anti- Fouling is the perfect fit for handling urban sewage water for industrial applications.
