Farming applications
Water quality is crucial in ensuring the well-being of farm animals such as cattle, chickens, sheep, and pigs, contributing significantly to optimal animal performance. Not only the quantity but also the purity of water influences desired growth outcomes.
Farms utilize water from various sources, including wells, civil water networks, and less commonly, rivers and other surface sources.
Apart from civil network water (which contains free chlorine), other sources often harbor high levels of dissolved solids, suspended particles, and pathogens. Consequently, reverse osmosis technology has proven to be the most effective in mitigating these challenges. For farms, it is imperative that contaminated water undergo comprehensive treatment to eliminate harmful substances, safeguarding the health of the animals.

Proshare Innovation Revolutionizing Reverse Osmosis Membrane Technology
Proshare Innovation Our pioneering team has brilliantly crafted a revolutionary new generation of reverse osmosis membranes, utilizing cutting-edge polymer interface nano-self-assembly technology. This innovative approach triumphs over the traditional constraints by achieving two monumental advancements:
Ultra-Thin Separation Layer Innovation: Through the mastery of polymer interface nanotechnology, our team has achieved a remarkable reduction in the separation layer thickness, rendering it at least three times thinner than the conventional polyamide thin films (previously restricted to 100 nm). This groundbreaking development drastically elevates water flux, leading to a remarkable enhancement in permeability.
Enhanced Membrane Performance: Thanks to the infusion of nanoparticles and specialized hydrophilic polymers, we have achieved significant strides in enhancing the membrane's hydrophilicity, anti-fouling properties, durability, and oxidation resistance.
In comparison to conventional polyamide reverse osmosis membranes, Proshare Innovation's cutting-edge solution showcases breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films Revolution
By harnessing nano-scale precision control and nano-doping modification, we enable the creation of ultra-thin, highly ordered separation layers through polymer interface nanotechnology. This sophisticated approach addresses the limitations of conventional polyamide membranes regarding thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, the functional layer thickness is expertly managed, achieving a 3x reduction compared to traditional membranes. This advancement results in over 3x higher water flux and 30% reduced energy consumption.
Advanced Polymer Materials Offering Superior Chemical Stability
Moving beyond the boundaries of polyamide, our team employs advanced hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These pioneering materials display extraordinary oxidation resistance (withstanding 10 ppm chlorine exposure) and pH resilience (maintaining stability across a pH range of 1-12).
Innovative Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (contact angle <10°) combined with nanoparticle reinforcement significantly reduces organic fouling propensity by 50%, extending chemical cleaning cycles from 3 months to 6 months and slashing maintenance costs by 40%.
