Farming applications

Water plays a crucial role in ensuring the health and productivity of farm animals, such as cattle, chickens, sheep, and pigs. The quality and quantity of water are pivotal factors that influence optimal animal growth and performance.
Farm water sources are varied, originating from water wells, civil water networks, and occasionally from rivers and other surface sources. These diverse origins require careful consideration to ensure water quality.
Excluding water from civil networks, which often contains free chlorine, other sources typically harbor high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most efficient method for mitigating these negative impacts. Contaminated farm water necessitates technological treatment to minimize harmful substances and safeguard animal health.

Our Advantages

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our innovative team at Proshare has ingeniously developed a cutting-edge generation of reverse osmosis membranes. Utilizing polymer interface nano-self-assembly technology, we have surmounted traditional limitations with two pivotal advancements:
Ultra-Thin Separation Layer: Through the application of advanced polymer interface nanotechnology, our team has remarkably minimized the separation layer's thickness to an unprecedented degree-at least three times thinner than the traditional polyamide thin film (previously confined to 100 nm). This groundbreaking achievement markedly boosts water flux, resulting in a substantial surge in permeability.
Enhanced Performance: By integrating nanoparticles with specialized hydrophilic polymers, we have achieved unprecedented strides in enhancing the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance.
Compared to conventional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation reveals breakthroughs in four pivotal domains:
Self-Assembled Nanocomposite Films
By harnessing nano-scale precision control and nano-doping modification, we have orchestrated the development of ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This innovative approach surmounts the constraints of standard polyamide membranes regarding thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, we precisely regulate the functional layer thickness, achieving a remarkable 3x reduction compared to conventional membranes. This translates into >3x higher water flux and 30% reduced energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing the realm of polyamide, our team employs state-of-the-art hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These groundbreaking materials exhibit exceptional oxidation resistance withstanding up to 10 ppm chlorine exposure, and pH tolerance maintaining stability across a pH range of 1-12.
Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (contact angle <10°) fortified with nanoparticle reinforcement significantly curtails organic fouling propensity by 50%, thereby extending chemical cleaning cycles from 3 months to 6 months and slashing maintenance costs by an impressive 40%.
