Fouling is a prevalent issue in RO membrane elements. While fouling doesn't alter the structure of RO membrane elements, it can drastically diminish performance by accumulating on the membrane surface.
Proshare's Anti-Fouling reverse osmosis (RO) technology combats fouling by utilizing a specialized hydrophilic coating on the membrane surface, ensuring prolonged stable operation. This prevention of fouling significantly cuts down cleaning frequency, ultimately reducing operational expenses (OPEX) for water treatment facilities.
Proshare's Anti- Fouling Solution effectively addresses the challenge of treating urban sewage water, making it ideal for industrial applications.

Our reverse osmosis desalination systems provide an alternative solution that meets the escalating water requirements of burgeoning touristic areas.
Farming applications
Water is a vital component in ensuring the well-being of livestock such as cattle, chickens, sheep, and pigs, essential for optimizing their productivity. The quality of water, as much as its quantity, plays a significant role in promoting the desired growth and performance of these animals.
Farm water can be sourced from a variety of origins, including water wells, public water networks, and, to a lesser extent, rivers and other surface sources.
Apart from water from public networks (which contains free chlorine), other sources typically harbor high concentrations of dissolved and suspended solids, along with pathogens. Reverse osmosis technology stands out as the most effective method to mitigate these detrimental effects. It is imperative that contaminated farm water undergoes technological treatment to reduce harmful substances to protect animal health.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our dedicated team has innovatively developed a revolutionary generation of reverse osmosis membranes, leveraging cutting-edge polymer interface nano-self-assembly technology. This groundbreaking work has successfully overcome the constraints traditionally faced in reverse osmosis membrane development through two pivotal advancements:
Ultra-Thin Separation Layer: Through the application of advanced polymer interface nanotechnology, we have achieved an unprecedented reduction in the separation layer's thickness-now at least three times thinner than the conventional polyamide thin film, previously limited to 100 nm. This monumental breakthrough significantly boosts water flux, delivering a remarkable enhancement in permeability.
Enhanced Performance: The infusion of nanoparticles and specialized hydrophilic polymers has catalyzed transformative advancements in the membrane's hydrophilicity, anti-fouling properties, durability, and oxidation resistance, setting new standards in membrane performance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's technological innovation marks groundbreaking advances across four essential dimensions:
Self-Assembled Nanocomposite Films
By integrating nano-scale precision control with nano-doping modification, we create ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This novel approach surpasses the limitations of conventional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
With the optimized layer-by-layer self-assembly process, functional layer thickness is precisely managed, achieving a remarkable 3x reduction compared to traditional membranes. This innovative process results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
By advancing beyond polyamide, we employ state-of-the-art hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These cutting-edge materials exhibit extraordinary oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (remaining stable across a broad pH range of 1-12).
Anti-Fouling Surface Engineering
Featuring a superhydrophilic surface (contact angle <10°) meticulously combined with nanoparticle reinforcement, the membrane's design dramatically reduces organic fouling propensity by 50%, extending chemical cleaning cycles from 3 months to 6 months, and significantly cutting maintenance costs by 40%.
