Farming Applications

Water is indispensable for ensuring optimal animal health (e.g., cattle, chickens, sheep, pigs) and maximizing their productivity. Not only does the quantity of water impact the desired growth of animals, but the quality is equally crucial, influencing their overall performance.
Farm water sources vary widely, including water wells, municipal water networks, and occasionally, rivers and other surface sources. Each source comes with unique qualities that need careful management.
Aside from water from municipal networks, which contains free chlorine, other sources often have high concentrations of dissolved and suspended solids and pathogens. Reverse osmosis technology proves to be the most effective method to mitigate these negative effects. Contaminated farm water should undergo advanced treatment to decrease harmful substances, safeguarding animal health.

Successful Cases Reference

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
For years, international luxury cruise ships have relied on a select few brands for their desalination membrane needs. The journey of a cruise ship presents varying feed water qualities, with fluctuations in salinity and temperature. Thus, the membranes employed must be capable of adjusting to these changes, all while delivering a consistent supply of fresh water to meet the rigorous demands of oceanic voyages.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes have proven to excel in both desalination efficiency and the steady production of water. The quality of the water produced by these membranes satisfies the exacting standards required by luxury cruise vessels.
Buoyed by this outstanding success, Proshare has secured additional contracts to replace desalination membranes on three more cruise ships. This marks Proshare's milestone achievement as the pioneering national brand to secure international luxury cruise ship orders for desalination RO membranes.

Our Advantages

Proshare Team's Groundbreaking Advances in Next-Generation Reverse Osmosis Membrane Technology
Proshare team has revolutionized the field by pioneering a new era of reverse osmosis membranes. Leveraging groundbreaking polymer interface nano-self-assembly technology, they have transcended the boundaries of traditional reverse osmosis membranes with two monumental advancements:
Ultra-Thin Separation Layer: Harnessing cutting-edge polymer interface nanotechnology, the team has astonishingly reduced the separation layer's thickness to an unprecedented level-three times thinner than the conventional polyamide thin film (formerly constrained to 100 nm). This extraordinary innovation markedly boosts water flux, achieving remarkable permeability enhancements.
Enhanced Performance: By incorporating state-of-the-art nanoparticles and uniquely designed hydrophilic polymers, Proshare has achieved revolutionary progress in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance, setting a new standard in performance.
In stark contrast to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases unprecedented breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films
Integrating nano-scale precision control with nano-doping innovation, Proshare crafts ultra-thin, meticulously ordered separation layers via advanced polymer interface nanotechnology. This strategic approach overcomes the inherent limitations in thickness uniformity and material diversity of conventional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
Through masterful optimization of the layer-by-layer self-assembly process, precise control over functional layer thickness is achieved, culminating in a notable 3x reduction compared to traditional membranes. This advancement delivers >3x superior water flux and 30% decreased energy consumption.
Innovative Polymer Materials with Unrivaled Chemical Stability
Pushing beyond the constraints of polyamide, Proshare employs avant-garde hydrophilic polymers, such as modified polysulfones and ceramic-organic hybrids. These materials showcase extraordinary oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH resilience (maintaining stability across a 1-12 pH range).
Revolutionary Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (with a contact angle of less than 10°) coupled with nanoparticle enhancements reduces organic fouling potential by an impressive 50%, extending chemical cleaning intervals from 3 to 6 months and slashing maintenance expenditures by 40%.
