Farming applications

Water plays a crucial role in ensuring the health and productivity of farm animals such as cattle, chickens, sheep, and pigs. The growth and performance of these animals are influenced not only by the quantity but also by the quality of the water they consume.
Farm water sources are diverse, ranging from water wells and civil water networks, to a lesser extent, rivers and other surface sources.
With the exception of civil network water (which contains free chlorine), other sources often have high levels of dissolved and suspended solids and pathogens. Consequently, reverse osmosis technology is the most effective method to mitigate these negative impacts. Contaminated farm water should undergo advanced treatment to eliminate harmful substances, ensuring animal health and welfare.

Our Advantages

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously pioneered a state-of-the-art generation of reverse osmosis membranes, leveraging cutting-edge polymer interface nano-self-assembly technology. This innovation triumphs over the constraints of traditional membrane development with two revolutionary breakthroughs:
Ultra-Thin Separation Layer: Utilizing advanced polymer interface nanotechnology, our team has remarkably minimized the separation layer's thickness, making it at least three times thinner than the conventional polyamide thin film, previously capped at 100 nm. This pioneering feat dramatically enhances water flux, ensuring a substantial leap in permeability.
Enhanced Performance: By introducing nanoparticles and specially designed hydrophilic polymers, we've achieved groundbreaking enhancements in hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance of the membrane.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases remarkable breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films
Through the fusion of nano-scale precision control and nano-doping modification, we craft ultra-thin, highly ordered separation layers using polymer interface nanotechnology. This strategy surpasses the conventional polyamide membrane constraints in thickness uniformity and material diversification.
Enhanced Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly process, our team meticulously controls the functional layer thickness, achieving a remarkable 3x reduction compared to traditional membranes. This innovation leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Moving beyond polyamide confines, our team employs advanced hydrophilic polymers, such as modified polysulfones, along with ceramic-organic hybrids. These innovative materials showcase exceptional oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability across a pH range of 1-12).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, featuring a contact angle of less than 10°, combined with nanoparticle reinforcement, diminishes organic fouling propensity by 50%. This advancement extends chemical cleaning cycles from three months to six months, slashing maintenance costs by an impressive 40%.
