For animal health and productivity (spanning cattle, chickens, sheep, and pigs), the caliber of water is as vital as its availability. Ensuring superior water quality is crucial to fostering desired growth and optimizing animal performance.
Farm water may be sourced from a variety of origins such as water wells, municipal water supplies, and occasionally rivers or other surface sources, each with unique properties.
With the exception of chlorine-treated municipal water, other sources frequently contain elevated levels of dissolved and suspended solids and pathogens. Therefore, reverse osmosis technology is the most proficient technique to alleviate these pollutants. It is essential for farm water, especially from non-municipal sources, to undergo technological treatment to reduce harmful elements, safeguarding the animals' health and well-being.

ProshareTeam's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
ProshareOur team at Proshare has achieved a monumental breakthrough with the creation of cutting-edge reverse osmosis membranes. By leveraging the advanced polymer interface nano-self-assembly technology, we have surmounted the common challenges inherent in traditional membrane fabrication, bringing forth two pioneering advancements:
Ultra-Thin Separation Layer: Through the masterful utilization of polymer interface nanotechnology, we have engineered a separation layer that is at least three times thinner than the conventional polyamide thin films, once bound by the 100 nm limitation. This transformative reduction in thickness significantly enhances water flux, resulting in a dramatic elevation in permeability.
Enhanced Performance: By incorporating nanoparticles and state-of-the-art hydrophilic polymers, we have reached remarkable milestones in enhancing the membrane's hydrophilicity, anti-fouling capability, durability, and oxidative resistance.
Compared to traditional polyamide reverse osmosis membranes,Proshare's innovation is distinct in delivering breakthroughs in four crucial areas:
Self-Assembled Nanocomposite Films
The synergy of nano-scale precision control with nano-doping modification facilitates the creation of ultra-thin, precisely structured separation layers using polymer interface nanotechnology. This groundbreaking approach surpasses the limitations in thickness uniformity and material diversity encountered in conventional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
By expertly refining the layer-by-layer self-assembly process, we have meticulously tuned the functional layer thickness, realizing an extraordinary threefold improvement over traditional membranes. This strategic advancement yields >3x higher water flux and 30% reduced energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Departing from polyamide, we utilize cutting-edge hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These innovative materials demonstrate exceptional oxidation resistance (enduring 10 ppm chlorine exposure) and pH tolerance (maintaining stability within the 1-12 pH range).
Anti-Fouling Surface Engineering
Our ultra-hydrophilic surface, engineered with a contact angle under 10° and reinforced by nanoparticles, reduces organic fouling by 50%. This innovation extends chemical cleaning intervals from 3 to 6 months, cutting maintenance costs by 40%.
