A common challenge with RO membrane elements is fouling, which can impede performance and efficiency. While fouling doesn't alter the structural integrity of the RO membrane elements, the accumulation of foulant on the membrane surface can substantially diminish its performance, a challenge we address with our innovative solutions.
Proshare Anti-Fouling reverse osmosis (RO) prevents fouling by applying a unique and exclusive hydrophilic coating to the membrane's surface. This pioneering approach ensures long-term stable operation. By mitigating fouling, cleaning frequency is reduced, ultimately leading to lower operational expenditure (OPEX) at your water treatment facility.
Proshare Anti- Fouling is tailored to meet your needs in treating urban sewage water for industrial applications, ensuring efficiency and sustainability.

Farming applications
Water is indispensable for ensuring the health and productive performance of farm animals like cattle, chickens, sheep, and pigs. Beyond mere quantity, the quality of water is crucial in influencing the desired growth outcomes.
Farm water sources vary, originating from water wells, civil water networks, and to a lesser extent, rivers and other surface sources.
Excluding water from civil networks (which contain free chlorine), other sources often exhibit high concentrations of dissolved solids, suspended solids, and pathogens. Reverse osmosis technology has proven to be the most effective method for mitigating these negative impacts, necessitating technological treatment of farm water to eliminate harmful substances and safeguard animal health.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our dedicated team at Proshare has ingeniously pioneered a cutting-edge generation of reverse osmosis membranes. Through the revolutionary approach of polymer interface nano-self-assembly technology, we've shattered the conventional barriers faced by traditional RO membrane development, marked by two transformative advancements:
Ultra-Thin Separation LayerWith the artful application of polymer interface nanotechnology, our team has impressively diminished the separation layer's thickness to a remarkable extent - at least threefold thinner than typical polyamide thin films, which were previously constrained to 100 nm. This monumental leap forward significantly boosts water flux, resulting in a remarkable surge in permeability.
Enhanced PerformanceThe infusion of nanoparticles, coupled with specially designed hydrophilic polymers, has driven revolutionary progress in membrane attributes, including enhanced hydrophilicity, superior anti-fouling capabilities, unparalleled durability, and exceptional oxidation resistance.
When benchmarked against conventional polyamide reverse osmosis membranes, Prosharedemonstrates groundbreaking advancements across four critical dimensions:
Self-Assembled Nanocomposite Films
Through the fusion of nano-scale precision control and nano-doping modification, we craft ultra-thin, intricately ordered separation layers utilizing polymer interface nanotechnology. This innovative methodology transcends the traditional polyamide membrane constraints of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly mechanism, we meticulously control the functional layer thickness, achieving an impressive threefold decrease compared to conventional membranes. This precision engineering yields an extraordinary >3x increase in water flux paired with a remarkable 30% reduction in energy consumption,setting new standards in efficiency and sustainability.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond the standard polyamide, our team harnesses advanced hydrophilic polymers, such as modified polysulfones, along with ceramic-organic hybrids. These innovative materials boast unparalleled oxidation resistance (withstanding exposure to 10 ppm chlorine) and robust pH tolerance (maintaining stability across a 1-12 pH range).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, combined with nanoparticle reinforcement, curtails organic fouling by a notable 50%.
