Agricultural Applications

Water is indispensable for ensuring the health of farm animals (e.g., cattle, chickens, sheep, pigs) and reaching optimal animal productivity. However, it's not merely the quantity but also the quality of water that significantly influences the animals' desired growth and performance.
Farm water sources can be diverse, originating from water wells, municipal water networks, and, to a lesser extent, rivers and other surface sources.
Apart from municipal networks (which contain free chlorine), other water sources typically possess high levels of dissolved and suspended solids as well as pathogens. Thus, reverse osmosis technology has proven to be highly effective in mitigating these adverse effects, necessitating technological treatment of contaminated water in farms to decrease substances potentially harmful to animals.

Our Advantages

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our pioneering team at Proshare has revolutionized reverse osmosis membranes by leveraging cutting-edge polymer interface nano-self-assembly technology. This innovation surmounts the challenges faced by traditional reverse osmosis membrane development through two pivotal advancements:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, the team has impressively minimized the separation layer thickness to at least three times thinner than the conventional polyamide thin films, which were previously capped at 100 nm. This groundbreaking development notably amplifies water flux, delivering a remarkable enhancement in permeability and efficiency.
Enhanced Performance: By incorporating nanoparticles alongside specialized hydrophilic polymers, we have achieved transformative progress in the membrane's hydrophilicity, anti-fouling capabilities, durability, and robust oxidation resistance.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovative approach manifests breakthroughs across four critical dimensions:
Self-Assembled Nanocomposite Films
Utilizing nano-scale precision control and nano-doping modification, our technology facilitates the formation of ultra-thin, highly organized separation layers through polymer interface nanotechnology. This technique transcends the constraints of conventional polyamide membranes concerning thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly procedure, we can meticulously control the functional layer thickness, achieving a remarkable threefold reduction compared to traditional membranes. This innovation results in a >3x increase in water flux while simultaneously achieving a 30% decrease in energy consumption,revolutionizing the efficiency of water treatment.
Novel Polymer Materials with Superior Chemical Stability
Departing from the limitations of polyamide, our team employs state-of-the-art hydrophilic polymers, such as modified polysulfones, alongside ceramic-organic hybrids. These materials offer outstanding oxidation resistance, withstanding up to 10 ppm of chlorine exposure, and demonstrate excellent pH stability across a wide range of 1 to 12 pH.
Anti-Fouling Surface Engineering
Featuring a superhydrophilic surface (contact angle <10°) and enhanced with nanoparticle reinforcement, our technology reduces the propensity for organic fouling by 50%, thereby extending the interval between chemical cleanings from 3 months to 6 months, and diminishing maintenance costs by an impressive 40%.
