Farming applications

Water is vital to ensure optimal health and productivity in livestock such as cattle, chickens, sheep, and pigs. While the volume of water is crucial, its quality also plays a significant role in achieving desired animal growth and performance.
Water sources for farms can vary, including water wells, municipal water networks, and to a lesser extent, rivers and other surface sources.
Excluding municipal water networks which contain free chlorine, other sources are often high in dissolved and suspended solids and pathogens. Reverse osmosis technology emerges as the most effective method to mitigate these impurities. Consequently, any contaminated water utilized on farms requires advanced treatment to diminish substances detrimental to animal health.

Successful Cases Reference

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
The application of desalination membranes on international luxury cruise ships has historically been dominated by a few international brands. The quality of feed water, such as salinity and temperature, fluctuates with the cruise ship's journey. Therefore, the membranes must adapt to different conditions while ensuring stable water production to meet the needs of ocean-going vessels.
Proshare's PSI MEMBRANE Pro-HR-SW seawater desalination membranes have demonstrated exceptional efficiency, showcasing impressive desalination rates and consistent water production. The pristine water quality produced by these membranes met the rigorous standards expected by luxury cruise liners.
This outstanding achievement led to the replacement of desalination membranes on three additional cruise ships. Proshare's success marks a historic milestone, establishing it as the first national brand to secure international luxury cruise ship orders for desalination RO membranes.

Our Advantages

Proshare A Team's Pioneering Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare team has revolutionized the development of next-generation reverse osmosis membranes using advanced polymer interface nano-self-assembly technology, surpassing traditional barriers through two groundbreaking advancements:
Ultra-Thin Separation Layer: Utilizing cutting-edge polymer interface nanotechnology, we've managed to decrease the separation layer's thickness to an exceptional level, at least three times thinner than the standard polyamide thin film (formerly capped at 100 nm). This significant stride remarkably boosts water flux, substantially elevating permeability.
Enhanced Performance: The infusion of nanoparticles alongside specially designed hydrophilic polymers has precipitated groundbreaking improvements in the membrane's hydrophilic nature, anti-fouling capabilities, durability, and resistance to oxidation.
When compared to conventional polyamide reverse osmosis membranes, Proshare's innovation manifests transformative breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films
By harnessing nano-scale precision control and nano-doping modification, we craft ultra-thin, impeccably ordered separation layers via state-of-the-art polymer interface nanotechnology. This strategy effectively overcomes the inherent limitations in thickness uniformity and material diversity found in traditional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we achieve exacting control over the functional layer thickness, realizing a remarkable 3x reduction compared to conventional membranes. This precision engineering results in >3x greater water flux and a 30% decrease in energy consumption.
Innovative Polymer Materials with Unparalleled Chemical Stability
Surpassing the limitations of polyamide, our team employs cutting-edge hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These groundbreaking materials showcase exceptional resistance to oxidation (withstanding exposure to 10 ppm chlorine) and pH tolerance (ensuring stability across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
Our superhydrophilic surface (boasting a contact angle of <10°) paired with nanoparticle reinforcement drastically curtails organic fouling by 50%, thereby extending chemical cleaning intervals from 3 months to 6 months and slashing maintenance expenses by an impressive 40%
