Farming Applications
Water plays an indispensable role in ensuring the well-being of farm animals (such as cattle, chickens, sheep, and pigs) and in achieving optimal productivity. Beyond quantity, the quality of water is equally paramount in fostering the desired growth and health of these animals.
Farm water can originate from various sources, including water wells, civil water networks, and, to a lesser degree, rivers and other surface sources.
Excluding civil water networks (which contain free chlorine), other sources typically present high concentrations of dissolved and suspended solids and pathogens. Consequently, reverse osmosis technology emerges as the most efficient tool for mitigating these adverse effects. By treating contaminated farm water through advanced technology, we can significantly reduce the presence of harmful substances, ensuring a healthier environment for livestock.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team at Proshare has ingeniously crafted a pioneering new generation of reverse osmosis membranes using cutting-edge polymer interface nano-self-assembly technology, effectively overcoming traditional development constraints with two pivotal breakthroughs:
Ultra-Thin Separation Layer: Through the masterful use of polymer interface nanotechnology, our team has astonishingly reduced the separation layer thickness to a remarkable one-third of the traditional polyamide thin film, formerly confined to 100 nm. This extraordinary feat significantly propels water flux, ushering in a dramatic leap in permeability.
Enhanced Performance: By incorporating nanoparticles alongside specialized hydrophilic polymers, we've unlocked revolutionary progress in hydrophilicity, anti-fouling, robustness, and oxidation resistance of the membrane.
Compared to conventional polyamide reverse osmosis membranes, Proshare's innovation marks monumental progress in four critical dimensions:
Self-Assembled Nanocomposite Films
With nano-scale precision control and nano-doping modification, we forge ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This method shatters the constraints of conventional polyamide membranes in terms of thickness uniformity and material versatility.
Enhanced Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly approach, we expertly manage functional layer thickness, achieving a reduction to one-third of that in traditional membranes. The outcome is >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Moving beyond polyamide, our team employs state-of-the-art hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials showcase unparalleled oxidation resistance (enduring 10 ppm chlorine exposure) and pH resilience (stable across a 1-12 pH range).
