- Achieve up to 30% loweroperating pressures :This membrane guarantees stellar salt-rejection performance with significantly lower pressures, enhancing operational efficiency.
- Reduced Cleaning Frequency:The TFN membrane's remarkable anti-fouling properties significantly diminish microbial and inorganic contaminants, leading to reduced necessity for frequent cleaning cycles.
- Extensive Cleaning pH Range 1-13:Boasting a wide cleaning pH range with high chemical tolerance, it ensures effective cleaning, unmatched durability, and robustness.
Key applications:
Perfect for water softening, producing ultra-pure water, and efficient water reuse, it's ideal for industries like
pharmaceuticals, electronics, power generation, petrochemical, refineries, food & beverage, and municipal sectors, among others.
A persistent issue with RO membrane elements is fouling, which, although not altering the membrane's structure, can substantially degrade its performance. While fouling does not alter the RO membrane's structure, the accumulation of foulants can severely impair its efficiency.
Proshare Anti-Fouling reverse osmosis (RO) effectively prevents fouling through an innovative hydrophilic surface coating, ensuring prolonged stable operation. This prevention of fouling results in reduced cleaning frequency, thereby contributing to decreased OPEX in water treatment facilities.
Proshare Anti- Fouling membrane solutions meet the demands of treating urban sewage water for industrial applications, ensuring reliable performance and sustainability.
