A common challenge faced by RO membrane elements is the issue of fouling. While fouling doesn't alter the fundamental structure of the RO membrane elements, the presence of foulants on the membrane surface can drastically impede its performance efficiency.
Proshare Anti-Fouling reverse osmosis (RO) offers a robust solution to fouling by utilizing a state-of-the-art hydrophilic coating on the membrane surface, which ensures sustained, stable operation over the long term. By mitigating fouling, the need for frequent cleaning is reduced, ultimately leading to decreased operational expenses (OPEX) at the water treatment facility.
Proshare Anti- Fouling is precisely engineered to meet your requirements for treating urban sewage water, tailored for industrial applications.

Farming applications
Water is indispensable for ensuring the optimal health and productivity of farm animals, such as cattle, chickens, sheep, and pigs. However, both the quantity and quality of water are pivotal in influencing the desired growth and performance of the animals.
Farm water can originate from diverse sources including water wells, municipal water networks, and, to a lesser extent, rivers and other surface sources.
Exempting municipal water (which contains free chlorine), other water sources often harbor high levels of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology has proven to be the most effective method for mitigating these detrimental effects. Thus, contaminated farm water should undergo advanced treatment to minimize substances harmful to animal health.
