Farming Applications

Water is indispensable for ensuring the fitness and optimal performance of farm animals, from cattle to chickens and sheep to pigs. It is not just the quantity but the pristine quality of water that influences the desired growth and productivity of animals.
Farm water sources vary widely, originating from wells, civil water networks, and occasionally rivers and other surface sources. Each source demands tailored solutions to ensure water quality and safety.
Excluding civil network water, often containing free chlorine, other water sources usually harbor a high concentration of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most efficient solution, reducing the negative effects of contaminated farm water. This technological treatment is essential to minimize harmful substances and safeguard animal health.

Successful Cases Reference

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
Historically, the use of desalination membranes on international luxury cruise ships has been led by a few dominant brands. With the journey of a cruise, factors like salinity and temperature of feed water often vary. Hence, membranes are required to adapt seamlessly to these fluctuating conditions while maintaining consistent water production, crucial for the demands of ocean-going vessels.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes have shown exceptional performance, excelling in both desalination rate and stable water production. These membranes ensured water quality that met the rigorous standards required by luxury cruise ships.
This extraordinary outcome resulted in the replacement of desalination membranes on three more cruise ships. This success story marks Proshare as the first national brand to secure international luxury cruise ship orders for desalination RO membranes.

Our Advantages

Proshare Pioneering Advancements in Next-Gen Reverse Osmosis Membrane Technology
Proshare Our visionary team has ingeniously pioneered a groundbreaking new generation of reverse osmosis membranes, leveraging state-of-the-art polymer interface nano-self-assembly technology. This innovative approach has shattered the constraints of traditional reverse osmosis membrane development with two pivotal breakthroughs:
Revolutionary Ultra-Thin Separation Layer: Harnessing cutting-edge polymer interface nanotechnology, our dynamic team has achieved an extraordinary reduction in the thickness of the separation layer, rendering it at least three times thinner than conventional polyamide thin films (previously restricted to 100 nm). This monumental breakthrough vastly enhances water flux, leading to a remarkable increase in permeability.
Unparalleled Performance Enhancement: Through the strategic integration of nanoparticles and bespoke hydrophilic polymers, we have unlocked unprecedented advancements in our membrane's hydrophilicity, anti-fouling capabilities, durability, and robust oxidation resistance.
When contrasted with traditional polyamide reverse osmosis membranes, Prosharehas achieved staggering breakthroughs in four essential dimensions:
Ingeniously Self-Assembled Nanocomposite Films
By seamlessly combining nano-scale precision control with nano-doping modification, we have crafted ultra-thin, meticulously ordered separation layers through sophisticated polymer interface nanotechnology. This remarkable technique transcends the limitations of traditional polyamide membranes in both thickness uniformity and material versatility.
Superior Enhanced Water Flux and Energy Optimization
Through expert optimization of our layer-by-layer self-assembly process, we have precisely controlled the functional layer thickness, achieving an extraordinary 3x reduction compared to conventional membranes. This exceptional innovation yields >3x augmented water flux and a 30% reduction in energy consumption,marking a significant leap in efficiency.
Innovative Polymer Materials with Remarkable Chemical Stability
Setting a new benchmark beyond polyamide, our team utilizes pioneering advanced hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These outstanding materials exhibit exceptional oxidation resistance (withstanding exposure to 10 ppm chlorine) and superior pH tolerance (maintaining stability across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
By employing a superhydrophilic surface (with a contact angle <10°) bolstered by nanoparticle reinforcement, we have successfully reduced the propensity for organic fouling by an impressive 50%. This advancement extends chemical cleaning cycles from 3 to 6 months, slashing maintenance costs by a remarkable 40%.
