A prevalent challenge with RO membrane elements is fouling. Although fouling does not alter the structural integrity of RO membrane elements, the presence of foulants on the membrane surface can dramatically diminish its performance efficiency.
Proshare Anti-Fouling reverse osmosis (RO) effectively thwarts fouling by employing a unique and exclusive hydrophilic coating seamlessly applied to the membrane surface, which ensures long-term stable operation. This innovative fouling prevention approach reduces cleaning frequency, contributing significantly to decreased operational expenditures (OPEX) at water treatment facilities.
Proshare Anti- Fouling perfectly meets your requirements for processing urban sewage water, making it ideal for industrial applications with unparalleled efficiency.
