Farming Applications

Water is the lifeblood of farming, ensuring the health and vitality of livestock such as cattle, chickens, sheep, and pigs, ultimately enhancing their performance. Both the quantity and the quality of this water are vital to achieving desired growth and productivity.
Farms utilize water sourced from diverse origins, including wells, civil water networks, and occasionally rivers or other surface sources. The varying quality of these sources necessitates vigilant management.
Excluding water from civil networks, which often contains free chlorine, other sources frequently harbor high levels of dissolved and suspended solids, as well as pathogens. Reverse osmosis technology emerges as the most effective method to mitigate these adverse effects, necessitating technological treatments to alleviate harmful substances in water used on farms to safeguard animal health.

Successful Cases Reference

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
Historically, the application of desalination membranes on international luxury cruise ships has been dominated by a select few international brands. As the cruise ship journeys through various regions, the feed water quality-encompassing salinity and temperature-fluctuates. Thus, the membranes must adeptly adapt to these varying conditions, ensuring consistently stable water production to meet the rigorous demands of ocean-going vessels.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes from Proshare exhibited exceptional performance, boasting an impressive desalination rate coupled with stable water production. The quality of water produced by these membranes surpassed the stringent requirements set by the cruise ship industry.
This outstanding achievement led to the replacement of desalination membranes on a further three luxury cruise ships, marking Proshare as the pioneering national brand to secure international luxury cruise ship orders for desalination RO membranes.

Our Advantages

Proshare's Pioneering Spirit Revolutionary Leap in Reverse Osmosis Membrane Technology
Proshare's Expertise Our dedicated team has taken a monumental leap forward by innovatively crafting a cutting-edge generation of reverse osmosis membranes. Leveraging the sophisticated polymer interface nano-self-assembly technology, they have adeptly bypassed the constraints traditionally associated with membrane development, achieving groundbreaking advancements in two pivotal areas:
Ultra-Thin Separation Layer Mastery: Utilizing state-of-the-art polymer interface nanotechnology, the team has astonishingly minimized the separation layer's thickness, rendering it at least three times thinner than the erstwhile standard polyamide films, which were capped at 100 nm. This monumental achievement propels water flux to new heights, dramatically boosting permeability.
Enhanced Performance and Durability: Through the strategic integration of nanoparticles and specialized hydrophilic polymers, we have unlocked unprecedented enhancements in hydrophilicity, anti-fouling capabilities, long-lasting durability, and resilience against oxidation.
In contrast to conventional polyamide-based reverse osmosis membranes, Proshare'strailblazing innovation signifies transformative progress in four critical domains:
Self-Assembled Nanocomposite Films
Harnessing the power of nano-scale precision control alongside nano-doping modification, we craft ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This innovative approach eclipses the limitations inherent in traditional polyamide membranes concerning thickness uniformity and material versatility.
Enhanced Water Flux and Superior Energy Efficiency
By meticulously refining our layer-by-layer self-assembly technique, we achieve unparalleled control over functional layer thickness, slashing it to one-third compared to conventional membranes. This innovation delivers over 3x the water flux coupled with a 30% reduction in energy consumption.
Innovative Polymer Materials Offering Unmatched Chemical Stability
Shifting beyond polyamide, our team employs cutting-edge hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These advanced materials boast exceptional resistance to oxidation (withstanding up to 10 ppm chlorine exposure) and pH resilience (maintaining stability across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
Featuring an ultra-superhydrophilic surface with a contact angle of less than 10°, bolstered by nanoparticle reinforcement, we slash organic fouling potential by 50%. This advancement prolongs chemical cleaning intervals from 3 to 6 months, significantly trimming maintenance expenses by 40%.
