A common challenge faced by RO membrane elements is fouling, a persistent issue. While fouling doesn't alter the RO membrane's structure, it significantly hampers its efficiency by amassing deposits on the surface.
Proshare Advanced Anti-Fouling Technology in reverse osmosis (RO) intricately prevents fouling by utilizing a patented hydrophilic coating on the membrane's exterior, ensuring sustained, stable operation. By mitigating fouling, it significantly decreases the need for frequent cleaning, thus lowering the operational expenditures (OPEX) of water treatment facilities.
Proshare's Advanced Anti- Fouling Solutions are perfectly tailored to meet your urban sewage water treatment needs, ideal for various industrial applications.

Farming Applications
Water quality is paramount in ensuring the health and performance of farm animals such as cattle, chickens, sheep, and pigs. Not only does the quantity of water impact growth, but its quality is crucial in achieving optimal productivity in livestock.
Farm water supplies may originate from diverse sources, including water wells, civil water networks, or, less frequently, rivers and surface water sources. Each source requires careful consideration to ensure suitability and safety.
Excluding chlorine-treated civil network water, alternative sources typically exhibit high levels of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology stands as the most effective solution to mitigate these adverse effects. Therefore, contaminated farm water should undergo technological treatment to eliminate substances harmful to livestock, promoting health and productivity.

Proshare Our Team's Pioneering Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously pioneered a groundbreaking new generation of reverse osmosis membranes utilizing state-of-the-art polymer interface nano-self-assembly technology. This innovative approach has triumphantly surmounted the constraints of traditional reverse osmosis membrane development through two pivotal advancements:
Ultra-Thin Revolutionary Separation Layer: Through the ingenious application of polymer interface nanotechnology, our team has remarkably slimmed down the separation layer to a mere fraction-at least three times thinner than its predecessors, the traditional polyamide thin film (previously constrained to 100 nm). This exceptional breakthrough substantially augments water flux, ushering in a dramatic enhancement in permeability.
Significantly Enhanced Performance: The strategic incorporation of nanoparticles and specialized hydrophilic polymers has catalyzed revolutionary advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance, setting new benchmarks for traditional polyamide reverse osmosis membranes.
Compared to the conventional polyamide reverse osmosis membranes, Proshare's avant-garde innovation showcases breakthroughs in four critical dimensions:
Self-Assembled Nanocomposite Films
The revolutionary fusion of nano-scale precision control with nano-doping modification empowers the creation of ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This cutting-edge method transcends the limitations of traditional polyamide membranes in achieving unrivaled thickness uniformity and material diversity.
Remarkable Water Flux and Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, the functional layer's thickness is precisely honed, resulting in an astounding 3x reduction in thickness compared to conventional membranes. This transformative innovation leads to >3x increased water flux, revolutionizing efficiency, coupled with an impressive 30% reduction in energy consumption,fostering sustainability.
Revolutionary Polymer Materials with Exceptional Chemical Stability
Stepping beyond conventional polyamide, our team employs cutting-edge hydrophilic polymers (such as modified polysulfones) along with ceramic-organic hybrids. These trailblazing materials boast extraordinary oxidation resistance (withstanding chlorine exposure up to 10 ppm) and unmatched pH tolerance (maintaining stability across a broad 1-12 pH spectrum).
Innovative Anti-Fouling Surface Engineering
By harnessing a superhydrophilic surface (contact angle <10°) fortified with nanoparticle reinforcement, we have achieved a remarkable 50% reduction in organic fouling propensity. This extends chemical cleaning cycles from 3 months to an impressive 6 months, simultaneously slashing maintenance costs by 40%-a testament to Proshare's commitment to operational efficiency and cost-effectiveness.
