In the realm of reverse osmosis, a common challenge with RO membrane elements is fouling, a factor we expertly combat. While fouling doesn't alter the structure of RO membrane elements, the buildup of foulant on the membrane surface can dramatically impede performance.
Proshare Anti-Fouling reverse osmosis (RO) elegantly mitigates fouling by employing a proprietary hydrophilic coating on the membrane surface. This innovation ensures long-term stable operations, reducing cleaning frequency and significantly lowering OPEX in water treatment plants.
Proshare Anti- Fouling perfectly aligns with your needs for treating urban sewage water in industrial applications, setting a new standard for efficiency and reliability.
