A common challenge with RO membrane elements is fouling. While fouling doesn't alter the structure of RO membranes, it significantly degrades performance by accumulating on the membrane surface.
Proshare Anti-Fouling reverse osmosis (RO) effectively prevents fouling through the application of a unique hydrophilic coating on the membrane's surface. This innovation ensures long-term stable operation and lowers cleaning frequency, which contributes to reduced operational expenses (OPEX) at water treatment plants.
Proshare Anti- Fouling is tailored to meet the demands of treating urban sewage water for industrial applications.

Proshare's vast experience in desalination technology extends to solutions for civil water desalination in hotels and touristic resorts. Providing a consistent fresh water supply is crucial for these infrastructures, and our R.O. seawater or brackish water desalination solutions are designed to meet the burgeoning needs of rapidly growing tourist areas, ensuring they can keep up with escalating water demands.
Farming applications
Water is vital to ensure the optimal health and productivity of farm animals such as cattle, chickens, sheep, and pigs. Not only does the quantity of water play a role in animal growth, but the quality is equally important to achieve peak performance.
Farms source water from various origins, including water wells, civil water networks, and to a lesser extent, rivers and other surface sources.
Excluding water from civil networks (which contains free chlorine), other sources often have high concentrations of dissolved and suspended solids and pathogens. Reverse osmosis technology stands out as the most effective method to mitigate these negative effects. Contaminated water used on farms should be treated with this advanced technology to remove harmful substances, safeguarding animal health.
