A prevalent challenge with RO Membrane Elements is fouling. Fouling does not alter the fundamental structure of RO Membrane Elements, yet the deposition of foulants on the membrane surface can drastically curtail its efficiency.
Proshare Anti-Fouling Reverse Osmosis (RO) combats fouling by deploying a unique hydrophilic coating on the membrane surface, assuring enduring, stable performance. By minimizing fouling, it reduces the cleaning frequency, thereby significantly lowering OPEX at water treatment facilities.
Proshare Anti- Fouling is perfectly suited to meet your needs in effectively treating urban sewage water for industrial applications.

Farming Applications
Water quality is crucial in ensuring the health and optimal performance of livestock, including cattle, chickens, sheep, and pigs. Not only does the quantity of water matter, but its quality also significantly impacts the animals' growth and productivity.
Farm water sources vary, originating from wells, civil water networks, and, to a lesser extent, rivers and surface sources.
Aside from civil network water, which contains free chlorine, other sources often harbor high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective method to mitigate these adverse effects. Contaminated farm water should undergo technological treatment to diminish substances detrimental to animal health.

Proshare Team's Revolutionary Leap in Advanced Reverse Osmosis Membrane Technology
Proshare Our team at Proshare has ingeniously devised a cutting-edge generation of reverse osmosis membranes, powered by the innovative polymer interface nano-self-assembly technology. This groundbreaking approach has transcended the constraints of traditional membrane development through two pivotal advancements:
Ultra-Thin Separation Layer: Leveraging the sophisticated polymer interface nanotechnology, our team has achieved a remarkable thinning of the separation layer, making it at least three times slimmer than the conventional polyamide thin film (historically capped at 100 nm). This advancement dramatically boosts the water flux, ushering in a new era of heightened permeability.
Enhanced Performance: By incorporating nanoparticles alongside specialized hydrophilic polymers, we have pioneered unprecedented enhancements in the membrane's hydrophilicity, anti-fouling properties, robustness, and resistance to oxidation.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovation reveals breakthroughs across four essential dimensions:
Self-Assembled Nanocomposite Films
Through the seamless fusion of nano-scale precision control and nano-doping modification, we have crafted ultra-thin, meticulously ordered separation layers by employing polymer interface nanotechnology. This innovative method surmounts the challenges of conventional polyamide membranes regarding thickness uniformity and material variety.
Enhanced Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly technique, the thickness of the functional layer is expertly regulated, realizing a reduction up to three times less than traditional membranes, which culminates in more than 3 times greater water flux and a remarkable 30% decrease in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Moving beyond the confines of polyamide, our team adopts cutting-edge hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials display extraordinary oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (remaining stable within a pH range of 1 to 12).
Anti-Fouling Surface Engineering
The integration of a superhydrophilic surface (with a contact angle under 10°) and nanoparticle reinforcement slashes the propensity for organic fouling by 50%. This advancement extends chemical cleaning intervals from 3 to 6 months and trims maintenance expenses by an impressive 40%.
We proudly showcase our esteemed certifications: the prestigious Health & Safety Management System Certificate, the comprehensive Environmental Management System Certificate, and the globally recognized ISO9001 Quality System Certificate.
