Agricultural Applications
Water is crucial in ensuring the optimal health and productivity of farm animals, such as cattle, chickens, sheep, and pigs. The growth and performance of these animals are influenced not just by the quantity, but also by the quality of water they receive.
Farm water may originate from diverse sources, including water wells, municipal water networks, and occasionally from rivers and other surface sources.
Excluding municipal water, which contains free chlorine, other sources often have high concentrations of dissolved and suspended solids and pathogens. Reverse osmosis technology proves to be the most efficacious method to mitigate these adverse effects. The contaminated farm water should therefore undergo advanced treatment processes to eliminate substances potentially harmful to animals.

Proshare The Team's Groundbreaking Achievements in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our team has innovatively pioneered a new era in reverse osmosis membranes, harnessing the power of polymer interface nano-self-assembly technology. This triumph overcomes the constraints of conventional reverse osmosis membrane advancements through two pivotal innovations:
Revolutionary Ultra-Thin Separation Layer: By leveraging advanced polymer interface nanotechnology, our team achieved an unprecedented reduction in separation layer thickness-now at least three times thinner than the traditional polyamide thin film, once capped at 100 nm. This leap forward dramatically boosts water flux, heralding a new epoch of enhanced permeability.
Superior Performance Enhancement: The infusion of nanoparticles and state-of-the-art hydrophilic polymers has spurred remarkable progress in the membrane's hydrophilicity, anti-fouling prowess, durability, and oxidation resistance.
In comparison to standard polyamide reverse osmosis membranes, Proshare's visionary innovation showcases breakthroughs in four critical dimensions:
Self-Assembled Nanocomposite Films
Through meticulous nano-scale precision control and nano-doping modification, we craft ultra-thin, impeccably ordered separation layers employing polymer interface nanotechnology. This cutting-edge method surmounts the barriers of traditional polyamide membranes in terms of thickness uniformity and material versatility.
Boosted Water Flux and Energy Efficiency
With expert optimization of the layer-by-layer self-assembly process, we meticulously regulate the functional layer thickness, achieving a remarkable 3x reduction compared to conventional membranes. This breakthrough yields more than 3x elevated water flux and a 30% reduction in energy consumption.
Innovative Polymer Materials with Unmatched Chemical Stability
Transcending the limitations of polyamide, our team harnesses cutting-edge hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials boast extraordinary oxidation resistance (withstanding up to 10 ppm chlorine exposure) and exceptional pH tolerance (maintaining stability across a broad 1-12 pH range).
Pioneering Anti-Fouling Surface Engineering
The ultra-superhydrophilic surface (boasting a contact angle of less than 10°) fortified with nanoparticle enhancements markedly diminishes organic fouling tendencies by 50%, extending chemical cleaning intervals from 3 to 6 months and slashing maintenance expenses by 40%.
