Farming Applications

Water plays a crucial role in ensuring the health and optimal performance of animals like cattle, chickens, sheep, and pigs. While water quantity is pivotal, its quality equally impacts the desired growth and productivity of the animals.
Farm water sources are diverse, originating from wells, civil networks, and occasionally from rivers and surface sources.
Apart from civil network water, which contains free chlorine, other sources often have high levels of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology emerges as the most effective method to mitigate these detrimental effects. Thus, farm water should undergo technological treatment to reduce harmful substances for animals.

Our Advantages

Proshare Pioneering Breakthroughs in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our dedicated team has ingeniously crafted a revolutionary generation of reverse osmosis membranes, leveraging polymer interface nano-self-assembly technology. This innovation triumphantly surmounts the traditional obstacles encountered in reverse osmosis membrane development through two pivotal advancements:
Ultra-Thin Separation Layer Innovation: Through astute application of polymer interface nanotechnology, our team has adeptly minimized the separation layer's thickness to an impressive threefold reduction of the usual polyamide thin film, which was formerly restricted to 100 nm. This remarkable leap forward substantially enhances water flux, leading to a significant boost in permeability.
Elevated Performance Metrics: The strategic incorporation of nanoparticles and bespoke hydrophilic polymers has heralded unparalleled advancements in the membrane's hydrophilicity, anti-fouling potential, robustness, and oxidation resistance.
In comparison with traditional polyamide reverse osmosis membranes, Proshare's innovations manifest breakthroughs across four critical dimensions:
Self-Assembled Nanocomposite Films
By masterfully integrating nano-scale precision control with nano-doping modification, the fabrication of ultra-thin, meticulously arranged separation layers is achieved through polymer interface nanotechnology. This method elegantly overcomes the challenges posed by conventional polyamide membranes in terms of thickness uniformity and material variety.
Enhanced Water Flux and Optimized Energy Efficiency
By refining the layer-by-layer self-assembly process, functional layer thickness is expertly regulated, achieving a reduction of over 3 times compared to conventional membranes. This culminates in >3x superior water flux and a 30% reduction in energy consumption.
Innovative Polymer Materials Boasting Exceptional Chemical Stability
Progressing beyond polyamide limitations, our team employs cutting-edge hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These materials showcase extraordinary oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH resilience (stable within a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (contact angle <10°), bolstered by nanoparticle fortification, diminishes organic fouling tendency by 50%, extending chemical cleaning cycles from 3 months to a remarkable 6 months, effectively reducing maintenance costs by 40%.
