Farming applications
Water is vital for ensuring optimal animal health and maximizing livestock productivity, whether it's cattle, chickens, sheep, or pigs. Both the quantity and quality of water are paramount in supporting desired growth rates.
Farm water can originate from various sources like water wells, municipal water networks, and occasionally from rivers or other surface sources.
Excluding municipal water networks (with free chlorine content), other sources often harbor high concentrations of dissolved and suspended solids and pathogens. Thus, reverse osmosis technology stands as the most efficient method to mitigate these negative effects. Contaminated farm water should undergo technological treatment to minimize harmful substances for animal well-being.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our dedicated team at Proshare has pioneered a revolutionary advancement in reverse osmosis membrane technology, harnessing the power of polymer interface nano-self-assembly. By breaking through the traditional constraints, we have made significant advancements in two critical areas:
Ultra-Thin Separation Layer: Utilizing cutting-edge polymer interface nanotechnology, we've achieved an extraordinary reduction in the separation layer's thickness, now at least three times thinner than the conventional polyamide thin film. This remarkable achievement translates into significantly enhanced water flux and a dramatic boost in permeability.
Enhanced Performance: Through the innovative integration of nanoparticles and advanced hydrophilic polymers, our membranes exhibit unparalleled improvements in hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance, setting a new standard in membrane performance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases groundbreaking advancements in four pivotal domains:
Self-Assembled Nanocomposite Films
With the fusion of nano-scale precision control and nano-doping modification, we've developed ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This innovative method addresses the limitations of traditional polyamide membranes regarding thickness uniformity and the diversity of materials used.
Enhanced Water Flux and Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, we precisely control the functional layer thickness, achieving a 3x reduction compared to traditional membranes. This leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Our approach transcends the limitations of polyamide by incorporating state-of-the-art hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These advanced materials showcase remarkable oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability within a pH range of 1-12).
Anti-Fouling Surface Engineering
Our engineered superhydrophilic surface, with a contact angle of less than 10°, coupled with nanoparticle reinforcement, reduces the likelihood of organic fouling by 50%. This innovation extends the chemical cleaning cycles from 3 to 6 months and reduces maintenance costs by 40%, delivering exceptional value and efficiency.
