Water is a critical element in ensuring optimal health and productivity of livestock, such as cattle, chickens, sheep, and pigs. The performance and growth of these animals are influenced not only by water quantity but significantly by its quality.
Farm water sources are diverse, originating from wells, civil water networks, and, to a lesser extent, rivers or other surface sources.
Excluding chlorine-rich civil network water, other sources often have elevated levels of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology has proven to be exceptionally effective in mitigating these contaminants, ensuring that farm water undergoes technological purification to reduce harmful substances for animals.

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. However, the journey of a cruise ship presents challenges such as fluctuating salinity and temperature in feed water. Thus, membranes must be versatile, adapting to diverse conditions while ensuring consistent water output to satisfy the demands of ocean-going vessels.
Proshare's PSI MEMBRANE Pro-HR-SW seawater desalination membranes exhibit outstanding performance with a superior desalination rate and stable water production, producing water that meets the stringent quality standards of luxury cruise ships.

Our Advantages

Proshare - Pioneering Excellence Revolutionary Breakthrough in Future-Ready Reverse Osmosis Membrane Technology
Proshare - Leading the Charge Our team has ingeniously pioneered a cutting-edge generation of reverse osmosis membranes through advanced polymer interface nano-self-assembly technology, shattering the constraints of conventional development with two groundbreaking innovations:
Ultra-Thin Separation Layer - A Leap Forward: Leveraging polymer interface nanotechnology, our team has achieved an astounding reduction in the separation layer's thickness, making it at least three times thinner than conventional polyamide thin films (which were previously constrained to 100 nm). This innovation dramatically boosts water flux, marking a remarkable leap in permeability.
Unprecedented Performance Enhancement: The strategic incorporation of nanoparticles and specially designed hydrophilic polymers has ushered in transformative improvements in the membrane's hydrophilicity, anti-fouling capacity, robustness, and resistance to oxidation.
In comparison to traditional polyamide reverse osmosis membranes, Proshare'sinnovation stands out with breakthroughs in four pivotal dimensions:
Self-Assembled Nanocomposite Films - Precision Redefined
Through the seamless fusion of nanoscale precision control and nano-doping modification, we craft ultra-thin, meticulously ordered separation layers utilizing polymer interface nanotechnology. This method transcends the traditional polyamide membranes' limitations in consistency and material versatility.
Elevated Water Flux and Superior Energy Efficiency
Through the refined optimization of the layer-by-layer self-assembly process, we achieve unparalleled control over functional layer thickness, resulting in a remarkable 3x reduction compared to traditional membranes. This advancement delivers >3x amplified water flux and a 30% reduction in energy consumption.
Innovative Polymer Materials with Unmatched Chemical Stability
Surpassing polyamide, our team expertly utilizes cutting-edge hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials exhibit extraordinary resistance to oxidation (capable of withstanding exposure to 10 ppm chlorine) and resilience across pH levels (maintaining stability within a 1-12 pH range).
Advanced Anti-Fouling Surface Engineering
The incorporation of a superhydrophilic surface (featuring a contact angle of less than 10°) alongside nanoparticle reinforcement leads to a 50% reduction in organic fouling potential, thereby extending chemical cleaning intervals from 3 months to an impressive 6 months, while slashing maintenance costs by 40%.
