Agricultural Applications
Water quality is crucial for ensuring optimal health and productivity of livestock such as cattle, chickens, sheep, and pigs. The quantity of water affects growth, but the quality is equally important for achieving desired animal performance.
Farms rely on diverse water sources, including wells, municipal networks, and to a lesser extent, rivers and other surface waters.
Aside from municipal water sources (which contain free chlorine), other sources often harbor high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology emerges as the most effective solution to mitigate these impurities, ensuring contaminated farm water undergoes technological treatment to remove harmful substances, thereby safeguarding animal health.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our dedicated team has ingeniously crafted a revolutionary new generation of reverse osmosis membranes utilizing cutting-edge polymer interface nano-self-assembly technology. This innovation triumphantly surmounts the limitations faced by traditional reverse osmosis membrane development through two pivotal advancements:
Ultra-Thin Separation Layer: Leveraging the power of polymer interface nanotechnology, our team has achieved a remarkable reduction in the thickness of the separation layer, making it at least three times thinner than traditional polyamide thin films (which were restricted to 100 nm thickness). This significant innovation dramatically boosts water flux, leading to a substantial enhancement in permeability.
Enhanced Performance: By integrating nanoparticles and specialized hydrophilic polymers, we have unlocked transformative advancements in hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance of the membranes, elevating their overall performance to unmatched levels.
Compared to conventional polyamide reverse osmosis membranes, Proshare's innovation showcases remarkable breakthroughs across four critical dimensions:
Self-Assembled Nanocomposite Films
Through the integration of nano-scale precision control and nano-doping modifications, we have crafted ultra-thin, highly ordered separation layers via polymer interface nanotechnology. This avant-garde approach effectively overcomes the traditional polyamide membranes' challenges concerning uniform thickness and material diversity.
Enhanced Water Flux and Energy Efficiency
By meticulously optimizing the layer-by-layer self-assembly process, we accurately control the functional layer thickness, achieving a threefold reduction compared to conventional membranes. This optimization results in more than three times higher water flux and a 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond polyamide, our team employs advanced hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials exhibit remarkable resistance to oxidation (withstanding exposure to 10 ppm chlorine) and tolerance for a wide pH range (stable from pH 1 to 12).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, combined with nanoparticle reinforcement, significantly reduces the propensity for organic fouling by 50%. This advancement extends chemical cleaning cycles from 3 months to 6 months, dramatically slashing maintenance costs by 40%.
