Farming applications
Water is the lifeline that ensures optimal health and productivity for farm animals like cattle, chickens, sheep, and pigs. Not just the quantity, but the quality of water is paramount to achieving desired growth and performance in livestock.
On farms, water sources can vary significantly, originating from water wells, civil water networks, and, to a lesser extent, rivers and other surface sources.
While civil network water often contains free chlorine, other sources typically harbor high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology proves to be the most effective solution to mitigate these adverse effects. Farm water, often contaminated, should undergo technological treatment to minimize harmful substances and ensure the health of the animals.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously pioneered a cutting-edge generation of reverse osmosis membranes, harnessing the power of polymer interface nano-self-assembly technology. By surpassing the conventional boundaries of traditional reverse osmosis membranes, this innovation offers two monumental advancements:
Ultra-Thin Separation Layer: Utilizing advanced polymer interface nanotechnology, our team has triumphantly achieved a separation layer that is at least thrice as thin as the conventional polyamide thin film, previously constrained at 100 nm. This extraordinary leap forward dramatically boosts water flux, signifying a remarkable enhancement in permeability.
Enhanced Performance: The infusion of nanoparticles and specialized hydrophilic polymers has propelled remarkable progress in the membrane's hydrophilicity, anti-fouling properties, durability, and resistance to oxidation.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's revolutionary innovation showcases breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films
Employing nano-scale precision control and nano-doping modification, we have developed ultra-thin, highly organized separation layers through polymer interface nanotechnology. This transformative approach addresses the challenges of thickness uniformity and material diversity found in conventional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we have precisely regulated the functional layer thickness, effectuating a 3x reduction compared to traditional membranes. This achievement results in over 3x higher water flux and a 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Advancing beyond polyamide, our team incorporates sophisticated hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These innovative materials showcase extraordinary resistance to oxidation (withstanding exposure to 10 ppm chlorine) and tolerance to pH variations (maintaining stability across a pH range of 1-12).
Anti-Fouling Surface Engineering
With a superhydrophilic surface (contact angle <10°) and reinforced with nanoparticles, we have reduced the propensity for organic fouling by 50%. This development extends chemical cleaning cycles from 3 months to 6 months, resulting in a 40% decrease in maintenance costs.
