Water is crucial for ensuring the health and productivity of animals like cattle, chickens, sheep, and pigs. Both the quantity and quality of water significantly influence the desired growth and performance of livestock.
Farm water can be sourced from wells, civil water networks, and, to a lesser extent, rivers or other surface sources. Each source brings its own challenges and considerations in maintaining optimal water quality for farm use.
Excluding water from civil networks which contain free chlorine, other sources often present high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology stands out as the most effective method to mitigate these adverse effects, ensuring contaminated farm water undergoes necessary technological treatment to remove harmful substances, safeguarding animal health.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our dedicated team has revolutionized reverse osmosis membranes by harnessing cutting-edge polymer interface nano-self-assembly technology. We've shattered the traditional barriers in membrane development with two transformative advancements:
Ultra-Thin Separation Layer: Through the ingenious application of polymer interface nanotechnology, our team has drastically reduced the separation layer's thickness to just a third of the typical polyamide thin film (once restricted to 100 nm). This innovation boosts water flux remarkably, resulting in a dramatic enhancement in permeability.
Enhanced Performance: By integrating nanoparticles with specialized hydrophilic polymers, we've achieved unprecedented enhancements in hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance for our membranes.
Compared to conventional polyamide reverse osmosis membranes, Proshare's innovation showcases breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films
With nano-scale precision control and nano-doping modification, we craft ultra-thin, highly ordered separation layers using polymer interface nanotechnology. This cutting-edge approach overcomes the limitations of traditional polyamide membranes regarding thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly process, we precisely control the functional layer thickness, achieving a 3x decrease compared to traditional membranes. This translates to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Pioneering beyond polyamide, we employ advanced hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids, which boast exceptional oxidation resistance (enduring 10 ppm chlorine exposure) and pH tolerance (maintaining stability in a wide 1-12 pH range).
Anti-Fouling Surface Engineering
Our superhydrophilic surfaces (with a contact angle <10°) combined with nanoparticle fortification slash organic fouling propensity by 50%. This innovation extends chemical cleaning intervals from 3 months to 6 months and reduces maintenance costs by an impressive 40%.
