Farming applications
Water is crucial to ensure the well-being of farm animals such as cattle, chickens, sheep, and pigs. It is essential not only to provide sufficient water but to ensure its quality to achieve optimal livestock productivity.
Farm water can originate from various sources, including water wells, civil water networks, and occasionally from rivers and other surface sources.
Except for water from civil networks (which contains free chlorine), other sources often have elevated levels of dissolved and suspended solids and pathogens. The reverse osmosis technology has been proven as the most effective method to mitigate these adverse effects. Farms should employ this technology to treat water and reduce harmful substances for animals.

Proshare Revolutionary Team Breakthrough in the Realm of Next-Generation Reverse Osmosis Membrane Technology
Proshare Our pioneering team has crafted a state-of-the-art generation of reverse osmosis membranes, employing cutting-edge polymer interface nano-self-assembly technology. This groundbreaking innovation transcends the constraints of traditional membrane development by achieving two monumental advancements:
Ultra-Thin Precision Separation Layer: Utilizing advanced polymer interface nanotechnology, our team has achieved a remarkable reduction in the separation layer's thickness, making it thrice as thin as the conventional polyamide thin film, which was historically capped at 100 nm. This significant breakthrough not only elevates water flux but also achieves an unprecedented boost in permeability, setting new industry standards.
Enhanced Performance and Durability: Through the ingenious integration of nanoparticles and specially engineered hydrophilic polymers, we've reached unprecedented heights in enhancing the membrane's hydrophilicity, anti-fouling capabilities, overall durability, and resistance to oxidation.
When compared to traditional polyamide reverse osmosis membranes, Proshare's revolutionary innovation showcases unparalleled breakthroughs in four essential aspects:
Self-Assembled Nanocomposite Films for Superior Performance
The synergy of nano-scale precision control and nano-doping modification enables the fabrication of ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This innovative method triumphs over the thickness uniformity and material diversity limitations inherent in conventional polyamide membranes.
Enhanced Water Flux Coupled with Superior Energy Efficiency
By perfecting the layer-by-layer self-assembly process, we precisely control the functional layer's thickness, achieving a dramatic 3x reduction relative to traditional membranes. This remarkable achievement results in >3x increased water flux while simultaneously ensuring 30% lower energy consumption,redefining efficiency.
Innovative Polymer Materials Featuring Exceptional Chemical Stability
Surpassing the confines of polyamide, our team leverages advanced hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These cutting-edge materials exhibit extraordinary oxidation resistance, capable of withstanding up to 10 ppm chlorine exposure and demonstrate remarkable pH stability, maintaining integrity across a 1-12 pH spectrum.
Pioneering Anti-Fouling Surface Engineering
A superhydrophilic surface with a contact angle of less than <10°, alongside nanoparticle reinforcement, dramatically reduces organic fouling propensity by an impressive 50%. This enhancement extends chemical cleaning intervals from 3 to 6 months, ultimately reducing maintenance costs by a substantial 40%.
