Farming Applications

Water quality is critical for ensuring animal health and optimizing livestock performance, such as cattle, chickens, sheep, and pigs. It's not just the volume but the quality of water that influences their growth and productivity.
Farms can source water from numerous origins, including wells, municipal networks, and to a lesser extent, rivers and surface sources. Each source presents unique challenges in terms of water quality and purity.
Except for municipal network water (which contains free chlorine), other sources often harbor high levels of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology has proven to be the most effective method to mitigate these issues, ensuring contaminated farm water undergoes treatment to eliminate harmful substances for animal health.

Our Advantages

Proshare Revolutionary Leap in Reverse Osmosis Membrane Technology by Our Team
Proshare Our team at Proshare boldly pioneers the next era of reverse osmosis membranes, leveraging cutting-edge polymer interface nano-self-assembly technology. This innovation triumphs over the constraints of traditional membranes with two monumental breakthroughs:
Revolutionary Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, our team has achieved an exceptional reduction in the separation layer's thickness, now at least three times thinner than its traditional polyamide counterparts (previously confined to 100 nm). This significant advancement not only enhances water flux but elevates permeability to new heights.
Performance Reimagined and Amplified: Through the strategic incorporation of nanoparticles and advanced hydrophilic polymers, we have propelled the membrane's hydrophilicity, anti-fouling capabilities, endurance, and resistance to oxidation to unprecedented levels.
When stacked against conventional polyamide reverse osmosis membranes, Proshare's innovation stands as a beacon of progress with breakthroughs in four transformative areas:
Pioneering Self-Assembled Nanocomposite Films
By seamlessly integrating nano-scale precision control and nano-doping modification, we have mastered the creation of ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This approach triumphs over the limitations of conventional polyamide membranes, addressing thickness uniformity and material diversity effectively.
Unmatched Water Flux and Energy Efficiency
With the optimization of the layer-by-layer self-assembly process, we achieve precise functional layer thickness control, resulting in a remarkable 3x reduction compared to traditional membranes, leading to >3x increased water flux and a remarkable 30% decrease in energy consumption.
Innovative Polymer Materials with Superior Chemical Stability
Surpassing the standard polyamide, our team employs advanced hydrophilic polymers (like modified polysulfones) and ceramic-organic hybrids. These materials boast extraordinary resistance to oxidation (withstanding 10 ppm chlorine exposure) and pH resilience (maintaining stability across a pH range of 1-12).
State-of-the-Art Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (boasting a contact angle of <10°) combined with nanoparticle reinforcement dramatically reduces organic fouling by 50%, thereby extending chemical cleaning intervals from every 3 months to 6 months and reducing maintenance expenses by 40%
