Farming Applications
High-quality water is essential for ensuring the health and optimal growth of farm animals such as cattle, chickens, sheep, and pigs. The quality of water, alongside its quantity, significantly impacts their productivity and overall wellbeing.
On farms, water is sourced from diverse origins such as wells, civil water networks, and occasionally, rivers and other surface sources.
With the exclusion of civil network water (often containing free chlorine), other sources typically possess high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology emerges as the most efficient method to mitigate these adverse effects, necessitating technological treatment to purify contaminated farm water and safeguard animal health.
Successful Cases Reference
Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
In the realm of international luxury cruise ships, the historical dominance of a select few international brands has marked the application of desalination membranes. As cruise ships traverse diverse waters, the quality of feed water often varies with changes in salinity and temperature. Hence, it is imperative for membranes to seamlessly adapt to these varying conditions while ensuring a consistent and stable water output, addressing the critical needs of ocean-going vessels.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes have showcased exceptional capabilities, excelling in both the desalination rate and the stability of water production. These membranes produce water of such high quality that it surpasses the stringent demands set by luxury cruise lines.
This outstanding achievement facilitated the replacement of desalination membranes on three more cruise ships. Proshare's triumph in this endeavor has positioned it as the pioneering national brand to secure international luxury cruise ship orders for desalination RO membranes.

Proshare Team's Revolutionary Leap in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our team at Proshare has ingeniously crafted a pioneering new generation of reverse osmosis membranes through the application of polymer interface nano-self-assembly technology. This breakthrough technology surmounts the challenges that have traditionally constrained reverse osmosis membrane development, thanks to two major advancements that stand as a testament to our innovation:
Ultra-Thin Separation Layer for Enhanced Efficiency: Utilizing advanced polymer interface nanotechnology, the team has remarkably reduced the separation layer thickness to a third of the traditional polyamide thin film's 100 nm limitation. This pioneering achievement dramatically boosts water flux, providing a marked enhancement in permeability.
Revolutionized Membrane Performance: By incorporating cutting-edge nanoparticles and uniquely engineered hydrophilic polymers, Proshare has realized unprecedented innovations in the membrane's hydrophilicity, anti-fouling performance, robustness, and resistance to oxidation.
In contrast to the traditional polyamide reverse osmosis membranes, Prosharehas revolutionized four critical aspects:
Self-Assembled Nanocomposite Films
By integrating nano-scale precision control and nano-doping techniques, we create ultra-thin, perfectly ordered separation layers using advanced polymer interface nanotechnology. This method effectively overcomes the limitations in thickness uniformity and material variety inherent to conventional polyamide membranes.
Maximized Water Flux and Optimized Energy Efficiency
Through an optimized layer-by-layer self-assembly process, we precisely manage the functional layer thickness, achieving a reduction 3x that of traditional membranes. This innovation leads to a staggering increase in water flux exceeding threefold and a remarkable 30% reduction in energy consumption.
Innovative Polymer Materials with Unparalleled Chemical Stability
Expanding beyond the confines of polyamide, our team employs cutting-edge hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These advanced materials offer outstanding resistance to oxidation (enduring exposure to 10 ppm chlorine) and robust pH tolerance (maintaining stability across a pH range of 1-12).
Sophisticated Anti-Fouling Surface Engineering
The exceptionally hydrophilic surface (contact angle <10°) combined with the reinforcement of nanoparticles reduces the likelihood of organic fouling by an impressive 50%, doubling the chemical cleaning intervals from 3 to 6 months, and significantly slashing maintenance costs by 40%.
