A pervasive challenge encountered with RO membrane elements is fouling, which can hinder optimal performance. While fouling doesn't alter the physical structure of RO membrane elements, the accumulation of foulants on the surface can substantially degrade their performance.
Proshare Anti-Fouling reverse osmosis (RO) technology effectively prevents fouling by utilizing a proprietary hydrophilic coating on the membrane surface. This innovation promotes long-term stable operation, reducing the frequency of cleaning cycles, and thereby significantly lowering operational expenses (OPEX) at water treatment facilities.
Proshare Anti- Fouling is perfectly suited to meet the demands of treating urban sewage water, catering specifically to industrial applications.

Farming Applications
Water is a critical factor in ensuring the health and productivity of farm animals such as cattle, chickens, sheep, and pigs. It's not just the quantity but the quality of water that can significantly impact the desired growth and performance of these animals.
Farm water can originate from various sources, including water wells, civil water networks, and to a lesser degree, rivers and other surface sources. Each source presents its own set of challenges.
Apart from civil networks (which contain free chlorine), other sources often have high levels of dissolved solids, suspended solids, and pathogens. Reverse osmosis technology emerges as the most effective solution to mitigate these adverse effects. It's imperative that the contaminated water used on farms undergo technological treatment to reduce harmful substances, safeguarding the wellbeing of the animals.
