Farming applications

   The water is essential in order to guarantee the fitness of the animals (e.g. cattle, chickens, sheep, pigs) and to achieve the best productive animals performance. However, not only the quantity of the water can influence the animals desired growth but also the quality of the water.
   The water used in the farm can have its origin from a number of different sources, such as water wells, civil water networks and to a less extent from rivers and other superficial sources.
   Excluding the water from civil networks (containing free chlorine), the other sources usually have a high concentration of dissolved and suspended solids and pathogens. Consequently,the reverse osmosis technology has demonstrated to be the most efficient technology to reduce their negative effects, the contaminated water used in the farms, should undergo technological treatment in order to reduce substances that can be harmful for the 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. 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 Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare team has innovatively developed a new generation of reverse osmosis membranes based on polymer interface nano-self-assembly technology, overcoming the limitations of traditional reverse osmosis membrane development through two key advancements:
Ultra-Thin Separation Layer: By employing polymer interface nanotechnology, the team successfully reduced the thickness of the separation layer to at least three times thinner than the traditional polyamide thin film (previously limited to 100 nm). This breakthrough significantly enhances water flux, achieving a substantial improvement in permeability.
Enhanced Performance: The introduction of nanoparticles and specialized hydrophilic polymers has led to groundbreaking advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation demonstrates breakthroughs in four key aspects:
Self-Assembled Nanocomposite Films
The integration of nano-scale precision control and nano-doping modification enables the creation of ultra-thin, highly ordered separation layers via polymer interface nanotechnology. This approach overcomes the limitations of conventional polyamide membranes in thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By optimizing the layer-by-layer self-assembly process, the functional layer thickness is precisely controlled, achieving a 3x reduction compared to traditional membranes. This results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Moving beyond polyamide, the team utilizes advanced hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These materials exhibit exceptional oxidation resistance (withstand 10 ppm chlorine exposure) and pH tolerance (stable in 1-12 pH range).
Anti-Fouling Surface Engineering
The superhydrophilic surface (contact angle <10°) combined with nanoparticle reinforcement reduces organic fouling propensity by 50%, extending chemical cleaning cycles from 3 months to 6 months and cutting maintenance costs by 40%
