Farming applications

Water is vital to ensure the health and optimal performance of livestock such as cattle, chickens, sheep, and pigs. However, it's not just the water quantity that matters-the quality is equally critical for achieving desired animal growth.
Farm water typically originates from diverse sources like water wells, civil water networks, and occasionally from rivers or other surface sources.
Aside from civil networks (which contain free chlorine), most water sources are high in dissolved solids, suspended particles, and pathogens. Reverse osmosis technology emerges as the most effective method to mitigate these impurities, ensuring that farm water is treated to minimize harm to animals, thereby safeguarding their health and productivity.

Our Advantages

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has showcased tremendous ingenuity by creating a pioneering generation of reverse osmosis membranes, leveraging the ground-breaking polymer interface nano-self-assembly technology. This innovation transcends the conventional boundaries of reverse osmosis membrane development through two pivotal advancements:
Ultra-Thin Separation Layer: Utilizing cutting-edge polymer interface nanotechnology, our team has triumphed in reducing the separation layer thickness to at least three times thinner than the traditional polyamide thin film, which was formerly constrained at 100 nm. This incredible achievement propels water flux to new heights, marking a substantial leap in permeability.
Enhanced Performance: The revolutionary implementation of nanoparticles and specialized hydrophilic polymers has catalyzed remarkable progress in enhancing the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation unveils breakthroughs in four transformative aspects:
Self-Assembled Nanocomposite Films
Through the integration of nano-scale precision control and nano-doping modification, we craft ultra-thin, meticulously ordered separation layers using advanced polymer interface nanotechnology. This novel method surpasses the constraints of traditional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly process, the functional layer's thickness is meticulously controlled, resulting in a dramatic 3x reduction compared to conventional membranes. This breakthrough delivers >3x higher water flux and an impressive 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing polyamide, the team utilizes cutting-edge hydrophilic polymers like modified polysulfones and innovative ceramic-organic hybrids. These materials showcase unparalleled oxidation resistance (withstanding exposure to 10 ppm chlorine) and extensive pH tolerance (maintaining stability across a 1-12 pH spectrum).
Anti-Fouling Surface Engineering
Our ultra-superhydrophilic surface (contact angle <10°) combined with nanoparticle reinforcement dramatically diminishes organic fouling potential by 50%, thereby doubling the chemical cleaning cycle duration from 3 to 6 months and slashing maintenance expenses by 40%.
