Farming applications
Water is essential to ensuring the optimal health and productivity of farm animals (e.g., cattle, chickens, sheep, pigs). Both the quantity and quality of water play pivotal roles in achieving desirable animal growth and performance.
Farm water sources may vary, including water wells, civil water networks, and to a lesser extent, rivers and other surface sources.
Excluding civil network water (which contains free chlorine), other water sources typically have high concentrations of dissolved and suspended solids and pathogens. As a result, reverse osmosis technology emerges as the most effective method to mitigate these negative effects. Contaminated farm water should undergo advanced technological treatment to minimize harmful substances and ensure animal health.

Proshare Team's Revolutionary Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our pioneering team at Proshare has ingeniously crafted a new era of reverse osmosis membranes, harnessing the power of polymer interface nano-self-assembly technology. This innovation transcends the constraints of traditional membrane development by achieving breakthroughs in two pivotal domains:
Ultra-Thin Separation Layer: Utilizing advanced polymer interface nanotechnology, our team has achieved a remarkable reduction in the thickness of the separation layer, making it at least three times thinner than conventional polyamide thin films, which were previously limited to 100 nm. This exceptional advancement considerably boosts water flux, offering a dramatic enhancement in permeability.
Enhanced Performance: Through the incorporation of cutting-edge nanoparticles and hydrophilic polymers, we have realized groundbreaking improvements in membrane hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance, setting new industry standards.
In comparison with traditional polyamide reverse osmosis membranes, Proshare's innovation stands out with significant breakthroughs in four crucial areas:
Self-Assembled Nanocomposite Films
By merging nano-scale precision control with nano-doping modifications, we create ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This technique surmounts the traditional limitations in thickness uniformity and material diversity found in conventional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, we have precisely controlled the functional layer thickness, achieving a remarkable 3x reduction compared to traditional membranes. This innovation results in >3x increased water flux and a 30% reduction in energy consumption.
Novel Polymer Materials with Unmatched Chemical Stability
Breaking away from traditional polyamide, our team employs advanced hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These materials demonstrate superior oxidation resistance (withstanding up to 10 ppm chlorine exposure) and pH resilience (stable within a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
Our superhydrophilic surface (contact angle <10°), coupled with nanoparticle reinforcement, reduces organic fouling potential by 50%. This extends chemical cleaning cycles from 3 months to 6 months, significantly cutting maintenance expenses by 40%
