A frequent challenge with RO membrane elements is the issue of fouling, which can compromise efficiency. While fouling does not alter the core structure of RO membrane elements, the accumulation of foulants on the surface can drastically impair performance.
Proshare Anti-Fouling reverse osmosis (RO) counteracts fouling through the application of a unique hydrophilic coating on the membrane surface. This innovation ensures long-term stable operation, reducing the frequency of cleaning and ultimately contributing to lower operational expenses (OPEX) at water treatment facilities.
Proshare Anti- Fouling is your definitive solution for the efficient treatment of urban sewage water, tailored for industrial applications.

Farming applications
Water is fundamental to ensuring the health and productivity of farm animals, such as cattle, chickens, sheep, and pigs. Both the quantity and quality of water are crucial for optimal animal growth.
On farms, water can originate from a variety of sources, including water wells, municipal water networks, and to a lesser extent, rivers and other surface sources.
Except for water from municipal networks (which contains free chlorine), other sources typically present high concentrations of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most efficient means to mitigate these adverse effects, thus contaminated farm water must undergo technological treatment to minimize harmful substances for animals.
