Farming applications
Water quality is paramount in farming to ensure the health and optimal performance of animals such as cattle, chickens, sheep, and pigs. Both the quantity and quality of water are critical in influencing desired animal growth and productivity.
Farms can source water from various origins, including water wells, civil water networks, and, to a lesser extent, rivers and other surface sources. Each source requires careful consideration and treatment to maintain water quality.
Excluding water from civil networks containing free chlorine, other sources typically contain high levels of dissolved and suspended solids and pathogens. Proshare's reverse osmosis technology has proven to be the most efficient method for mitigating these harmful effects. Thus, contaminated farm water should undergo technological treatment to eliminate harmful substances and ensure animal health and growth.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team at Proshare has ingeniously pioneered an advanced generation of reverse osmosis membranes, utilizing cutting-edge polymer interface nano-self-assembly technology. This groundbreaking development has triumphantly surpassed the traditional constraints of reverse osmosis membrane design through two pivotal advancements:
Ultra-Thin Separation Layer: By harnessing the power of polymer interface nanotechnology, our team has achieved a remarkable reduction in separation layer thickness, making it at least three times thinner than the conventional polyamide thin film, which was previously restricted to 100 nm. This monumental breakthrough tremendously enhances water flux, markedly boosting permeability.
Enhanced Performance: The incorporation of nanoparticles and specialized hydrophilic polymers has ushered in revolutionary advancements in membrane hydrophilicity, anti-fouling capability, durability, and oxidation resistance-setting new standards in performance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases pioneering advancements across four crucial dimensions:
Self-Assembled Nanocomposite Films
Through the seamless fusion of nano-scale precision control and nano-doping modification, we craft ultra-thin, highly ordered separation layers by leveraging polymer interface nanotechnology. This strategy effectively overcomes the conventional limitations in thickness uniformity and material diversity seen in polyamide membranes.
Enhanced Water Flux and Energy Efficiency
Thanks to the meticulous optimization of the layer-by-layer self-assembly process, the functional layer thickness is precisely controlled, achieving an impressive 3x reduction compared to traditional membranes. This results in >3x higher water flux and 30% lower energy consumption,capturing efficiency at its finest.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond polyamide, our team employs state-of-the-art hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials exhibit outstanding oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (remaining stable across a 1-12 pH range).
