Farming applications
Water is a critical element to ensure the vitality and peak performance of livestock such as cattle, chickens, sheep, and pigs. Not only does the volume of water impact animal growth, but the quality is equally crucial. Ensuring optimal water quality is key to achieving the best productive performance in animals.
Farm water can originate from diverse sources including water wells, civil water networks, and to a lesser degree, rivers and other surface sources.
Apart from civil networks (which contain free chlorine), other sources often exhibit high levels of dissolved and suspended solids along with pathogens. Reverse osmosis technology stands out as the most efficient means to mitigate these harmful effects. Therefore, contaminated farm water should undergo sophisticated treatment to reduce harmful substances, safeguarding animal health.

Proshare Pioneering Advances in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has made a groundbreaking leap in reverse osmosis membrane innovation, leveraging cutting-edge polymer interface nano-self-assembly technology. This has allowed us to transcend traditional limitations, achieving two phenomenal advancements:
Ultra-Thin Separation Layer: Utilizing revolutionary polymer interface nanotechnology, our team has ingeniously reduced the separation layer's thickness to a remarkable threefold thinner than conventional polyamide films (formerly constrained to 100 nm). This significant breakthrough propels water flux, resulting in a dramatic elevation in permeability.
Enhanced Performance: By integrating nanoparticles with specialized hydrophilic polymers, we have ushered in transformative advancements in the membrane's hydrophilicity, anti-fouling ability, durability, and resistance to oxidation.
In comparison to standard polyamide reverse osmosis membranes, Proshare's cutting-edge innovation reveals breakthroughs in four critical dimensions:
Self-Assembled Nanocomposite Films
Through the fusion of nano-scale precision control and sophisticated nano-doping modification, we create ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This sophisticated approach surmounts the restrictions of traditional polyamide membranes in terms of thickness consistency and material versatility.
Enhanced Water Flux and Energy Efficiency
By masterfully optimizing the layer-by-layer self-assembly process, we precisely control the functional layer thickness, achieving an impressive 3x reduction compared to traditional membranes. This innovation delivers >3x higher water flux and 30% lower energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
Breaking away from polyamide, our team employs state-of-the-art hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials showcase outstanding oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH resilience (maintaining stability across a 1-12 pH spectrum).
Anti-Fouling Surface Engineering
Our superhydrophilic surface (with a contact angle <10°), reinforced with nanoparticles, slashes organic fouling inclination by 50%, effectively doubling chemical cleaning intervals from 3 to 6 months, and reducing maintenance expenses by 40%.
