Farming Applications
Water is vital to ensure the health and productivity of farm animals, such as cattle, chickens, sheep, and pigs. However, both the quantity and quality of water are crucial for optimal animal growth and performance.
Farm water supply originates from various sources such as water wells, civil water networks, and, to a lesser extent, rivers or other surface sources.
With the exception of water from civil networks (containing free chlorine), other sources often possess high levels of dissolved and suspended solids and pathogens. Therefore, reverse osmosis technology has proven to be the most effective method to mitigate the adverse effects of contaminated farm water. This technological treatment is essential to reduce harmful substances, safeguarding animal health.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has revolutionized the field with an innovative new generation of reverse osmosis membranes, crafted with precision using polymer interface nano-self-assembly technology. This cutting-edge approach has shattered the constraints of conventional reverse osmosis membrane development through two pivotal advancements:
Ultra-Thin Separation Layer: Utilizing advanced polymer interface nanotechnology, our team has remarkably minimized the separation layer's thickness, achieving a reduction to at least three times thinner than the traditional 100 nm polyamide thin film. This extraordinary leap forward markedly boosts water flux, offering a phenomenal improvement in permeability.
Enhanced Performance: The strategic incorporation of nanoparticles and cutting-edge hydrophilic polymers has resulted in unprecedented enhancements in membrane hydrophilicity, anti-fouling properties, durability, and resistance to oxidation.
Compared to conventional polyamide reverse osmosis membranes, Proshare's innovation showcases remarkable breakthroughs in four critical areas:
Self-Assembled Nanocomposite Films
Through the fusion of nano-scale precision control and nano-doping modification, we have crafted ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This methodology transcends the limitations of traditional polyamide membranes in terms of thickness uniformity and material versatility.
Enhanced Water Flux and Energy Efficiency
By meticulously refining the layer-by-layer self-assembly process, we precisely control functional layer thickness, achieving an impressive 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
Progressing beyond polyamide, we leverage state-of-the-art hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials exhibit extraordinary oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (remaining stable across a pH range of 1-12).
Anti-Fouling Surface Engineering
Our superhydrophilic surface design (contact angle <10°), enhanced with nanoparticle reinforcement, significantly reduces the propensity for organic fouling by 50%. This extends chemical cleaning cycles from 3 months to 6 months, dramatically cutting maintenance costs by 40%.
