Farming applications

Water is indispensable for ensuring the health and optimal performance of farm animals, such as cattle, chickens, sheep, and pigs. Not only does the quantity of water matter, but its quality is crucial for the desired growth and productivity of the animals.
The water utilized on farms is sourced from various origins, including water wells, civil water networks, and occasionally rivers and other surface sources.
While water from civil networks (often containing free chlorine) is typically safe, other sources may possess high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective method to mitigate these negative impacts. It is vital that contaminated farm water undergoes technological treatment to reduce harmful substances, safeguarding 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.
PSI MEMBRANE Pro-HR-SW seawater desalination membranes demonstrated superior performance in both desalination rate and stable water production. The water quality produced by these membranes met the stringent requirements of the cruise ship.
This remarkable result led to the replacement of desalination membranes on three additional cruise ships. Proshare's success in this venture establishes it as the first national brand to win international luxury cruise ship orders for desalination RO membranes.

Our Advantages

Proshare The Team's Breakthrough in Pioneering Next-Generation Reverse Osmosis Membrane Technology
Proshare Our visionary team has ingeniously crafted a cutting-edge generation of reverse osmosis membranes by harnessing the transformative power of polymer interface nano-self-assembly technology. This remarkable innovation triumphs over the constraints of traditional reverse osmosis membrane advancements through two pivotal enhancements:
Ultra-Thin Separation Layer: Utilizing state-of-the-art polymer interface nanotechnology, we've accomplished the phenomenal reduction in separation layer thickness to less than a third of the conventional polyamide thin film, previously capped at 100 nm. This extraordinary achievement greatly amplifies water flux and marks a monumental leap in permeability enhancement.
Enhanced Performance: The strategic incorporation of nanoparticles and specialized hydrophilic polymers has culminated in revolutionary improvements in the membrane's hydrophilicity, anti-fouling prowess, durability, and resistance to oxidation.
Compared to traditional polyamide reverse osmosis membranes, Proshare's trailblazing innovation showcases transformative breakthroughs across four essential dimensions:
Self-Assembled Nanocomposite Films
Through precision nano-scale control and nano-doping modifications, we've achieved the creation of ultra-thin, impeccably ordered separation layers using polymer interface nanotechnology. This groundbreaking technique surpasses the limitations of conventional polyamide membranes regarding thickness uniformity and material versatility.
Enhanced Water Flux and Energy Efficiency
By finely optimizing the intricate layer-by-layer self-assembly process, we precisely control the functional layer thickness, attaining a remarkable threefold reduction compared to traditional membranes. This astounding advancement results in >3x higher water flux and 30% lower energy consumption.
Innovative Polymer Materials with Unparalleled Chemical Stability
Surpassing traditional polyamide, we leverage cutting-edge hydrophilic polymers like modified polysulfones and ceramic-organic hybrids. These advanced materials showcase remarkable oxidation resistance (capable of enduring 10 ppm chlorine exposure) and pH tolerance (maintaining stability across a 1-12 pH range).
Anti-Fouling Surface Engineering
Boasting a superhydrophilic surface (contact angle <10°) fortified with nanoparticle enhancements, our membranes reduce organic fouling tendency by 50%, effectively prolonging chemical cleaning cycles from 3 months to 6 months and slashing maintenance expenses by 40%
