Farming Applications
Water is vital for ensuring the health and optimal performance of animals such as cattle, chickens, sheep, and pigs. The quality and quantity of water significantly influence the desired growth and productivity of livestock.
Farm water sources vary widely, originating from water wells, civil water networks, and to a lesser degree, rivers and other surface sources.
Except for water from civil networks (which contain free chlorine), other sources often have high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective in minimizing these detrimental effects. Contaminated farm water must undergo advanced treatment to reduce substances harmful to animals.

Proshare Revolutionary Leap in Reverse Osmosis Membrane Innovation by Our Expert Team
Proshare Our pioneering team has masterfully crafted a state-of-the-art generation of reverse osmosis membranes employing cutting-edge polymer interface nano-self-assembly technology. This innovation transcends the boundaries of traditional membrane development by achieving two pivotal breakthroughs:
Revolutionarily Ultra-Thin Separation Layer: By leveraging advanced polymer interface nanotechnology, the team has remarkably minimized the separation layer thickness to a groundbreaking thinness-at least three times thinner than the conventional polyamide thin film which was previously constrained to 100 nm. This monumental achievement results in significantly enhanced water flux, ushering in a new era of permeability improvements.
Superior Performance Enhancements: The strategic incorporation of nanoparticles coupled with specially engineered hydrophilic polymers marks a groundbreaking leap in membrane science. These advancements have revolutionized the membrane's hydrophilicity, anti-fouling capabilities, durability, and resilience to oxidation, setting new industry standards.
In stark contrast to conventional polyamide reverse osmosis membranes, Proshare's trailblazing innovation stands out with remarkable breakthroughs across four critical dimensions:
Self-Assembled Nanocomposite Films for Unmatched Efficiency
Integrating nano-scale precision control with nano-doping modification, this innovation crafts ultra-thin, impeccably ordered separation layers through polymer interface nanotechnology. This avant-garde approach triumphs over the conventional polyamide membranes' limitations in achieving uniform thickness and diverse material applications.
Unprecedented Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, the functional layer thickness is precisely honed, resulting in a remarkable 3x reduction compared to traditional membranes. This leads to an impressive outcome of >3x enhanced water flux and a 30% reduction in energy consumption.
Innovative Polymer Materials with Unrivalled Chemical Stability
Surpassing the boundaries of polyamide, the team adopts cutting-edge hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials showcase extraordinary oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and broad pH resilience (maintaining stability across a wide pH range of 1 to 12).
Innovative Anti-Fouling Surface Engineering
