Farming applications

Water is crucial for ensuring the well-being of farm animals like cattle, chickens, sheep, and pigs, and for optimizing their productive performance. The quality, not just the quantity, of water is vital for fostering the desired growth of these animals.
Water utilized on farms may originate from various sources, including water wells, civil water networks, and, to a lesser extent, rivers and other surface sources.
Excluding civil network water (which contains free chlorine), other sources often harbor high levels of dissolved and suspended solids and pathogens. Thus, reverse osmosis technology stands out as the most effective method to mitigate these harmful effects. Contaminated water in farms must undergo technological treatment to reduce substances harmful 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. As cruise ships sail across varying climates, the water feed changes in salinity and temperature, demanding adaptable membranes. These must maintain consistent high-quality water production to fulfill the rigorous demands of ocean-going vessels.
PSI MEMBRANE Pro-HR-SW seawater desalination membranes have set a new benchmark with their exceptional desalination rate and consistent water output. The water produced by these membranes has exceeded the stringent quality standards expected on a luxury cruise ship.
This outstanding performance led to the adoption of our membranes on three more cruise ships. Proshare's achievement marks a significant milestone as the first national brand to secure prestigious international luxury cruise ship orders for desalination RO membranes.

Our Advantages

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our pioneering team at Proshare has spearheaded the development of an innovative new generation of reverse osmosis membranes. This cutting-edge advancement is rooted in polymer interface nano-self-assembly technology, allowing us to surpass the limitations traditionally faced in reverse osmosis membrane technology through two remarkable breakthroughs:
Ultra-Thin Separation Layer: Utilizing state-of-the-art polymer interface nanotechnology, our team has revolutionized membrane design by drastically minimizing the separation layer's thickness, achieving a layer that is at least three times thinner than conventional polyamide thin films, previously constrained to 100 nm. This significant innovation markedly boosts water flux, culminating in a dramatic enhancement in permeability.
Enhanced Performance: The clever fusion of nanoparticles with specialized hydrophilic polymers has ushered in transformative progress in enhancing the membrane's hydrophilicity, anti-fouling capabilities, durability, and resistance to oxidation.
In contrast to traditional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation marks significant advancements in four pivotal areas:
Self-Assembled Nanocomposite Films
Through the seamless integration of nano-scale precision control and nano-doping modification, we have created ultra-thin, highly ordered separation layers using advanced polymer interface nanotechnology. This innovative methodology triumphantly overcomes the constraints of conventional polyamide membranes concerning thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By meticulously optimizing the layer-by-layer self-assembly process, we exert precise control over the functional layer thickness, achieving a remarkable 3x reduction compared to traditional membranes. This precision leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Our team boldly transcends traditional polyamide by employing cutting-edge hydrophilic polymers, such as modified polysulfones, and robust ceramic-organic hybrids. These advanced materials showcase extraordinary oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (remaining stable across a 1-12 pH range).
Anti-Fouling Surface Engineering
With an exceptionally superhydrophilic surface (contact angle <10°) reinforced by nanoparticles, we have effectively reduced the propensity for organic fouling by 50%, thereby extending chemical cleaning cycles from 3 to 6 months and significantly cutting maintenance costs by 40%.
