A common challenge faced by RO membrane elements is fouling, which can hinder performance. While fouling does not alter the inherent structure of RO membrane elements, the accumulation of foulants on the membrane surface significantly diminishes their performance efficiency.
Proshare Anti-Fouling reverse osmosis (RO) is engineered to prevent fouling through the application of a cutting-edge, exclusive hydrophilic coating on the membrane surface, promoting long-term stable operation. By effectively preventing fouling, this innovation reduces the frequency of necessary cleanings, thereby contributing to a significant reduction in OPEX at the water treatment plant.
Proshare Anti- Fouling is the perfect solution for meeting your urban sewage water treatment demands, tailored for industrial applications with unmatched efficiency and reliability.

Farming applications
Water is pivotal in ensuring the health and productivity of animals such as cattle, chickens, sheep, and pigs. The quality, along with the quantity of water, is crucial in achieving optimal animal growth and performance.
Farm water may originate from diverse sources, including water wells, civil water networks, and, to a lesser extent, rivers or other surface sources.
Excluding water from civil networks, which contains free chlorine, other sources typically have high concentrations of dissolved solids, suspended solids, and pathogens. Reverse osmosis technology is the most effective solution to mitigate these adverse effects. Contaminated farm water should undergo technological treatment to remove substances harmful to animal health.
