A common challenge faced by RO membrane elements is fouling, which can impact performance significantly. Fouling does not alter the structural integrity of RO membrane elements, but accumulation on the membrane surface can drastically reduce their efficiency.
Proshare Anti-Fouling reverse osmosis (RO) prevents fouling by employing a state-of-the-art hydrophilic coating on the membrane surface. This innovative approach ensures long-term stable operation, minimizing fouling to effectively reduce cleaning frequency, ultimately leading to a lower operational expenditure (OPEX) at the water treatment facility.
Proshare Anti- Fouling is the ideal solution for your requirements in treating urban sewage water for industrial applications.
