Farming applications

Water quality is crucial to ensure the health and optimal performance of farm animals, such as cattle, chickens, sheep, and pigs. The quality of water, not just its quantity, plays a significant role in enhancing the desired growth of animals.
Farming operations may source water from various origins including wells, civil water networks, and, to a lesser extent, rivers and other surface sources.
Apart from water from civil networks, which contains free chlorine, other sources often have high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective in mitigating these adverse effects. Consequently, farm water should undergo technological treatments to eliminate harmful substances impacting animal health.

Successful Cases Reference

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
The deployment of desalination membranes on luxurious international cruise liners has traditionally been monopolized by a select few global brands. Given the variability in feed water quality, such as salinity and temperature during a cruise's travel, these membranes need to dynamically adapt to fluctuating conditions while maintaining consistent water production to fulfill the demands of ocean voyages.
PSI MEMBRANE Pro-HR-SW seawater desalination membranes exhibit outstanding performance in both desalination rate and reliable water production. The produced water quality from these membranes aligns with the rigorous standards expected by cruise ships.
This outstanding achievement led to the replacement of desalination membranes on three more cruise ships. Proshare's triumph in this endeavor marks it as the pioneer national brand securing international luxury cruise ship contracts for desalination RO membranes.

Our Advantages

Proshare Revolutionary Advancement in Reverse Osmosis Membrane Technology
Proshare Our visionary team has pioneered a cutting-edge generation of reverse osmosis membranes through the innovative application of polymer interface nano-self-assembly technology. With remarkable foresight, we've overcome traditional reverse osmosis membrane limitations with two groundbreaking breakthroughs:
Ultra-Refined Separation Layer: Leveraging advanced polymer interface nanotechnology, we have astoundingly minimized the separation layer's thickness to a mere third of the standard polyamide thin film's 100 nm limit. This revolutionary achievement catapults water flux to new heights, dramatically enhancing permeability.
Superior Performance Enhancement: The strategic incorporation of innovative nanoparticles and specialized hydrophilic polymers propels our membrane's hydrophilicity, anti-fouling prowess, durability, and oxidation resistance to unparalleled levels.
In stark contrast to conventional polyamide reverse osmosis membranes, Proshare's visionary innovation showcases groundbreaking achievements in four pivotal domains:
Self-Assembled Nanocomposite Films
Our sophisticated integration of nano-scale precision control and nano-doping modification crafts ultra-thin, meticulously ordered separation layers utilizing polymer interface nanotechnology, overcoming conventional polyamide membrane constraints in thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we've precisely regulated the functional layer thickness, culminating in a remarkable 3-fold reduction compared to traditional membranes. The outcome is >3x increased water flux coupled with a 30% reduction in energy consumption.
Cutting-Edge Polymer Materials with Exceptional Chemical Stability
Transcending polyamide limitations, our team harnesses the power of advanced hydrophilic polymers, such as modified polysulfones, and pioneering ceramic-organic hybrids. These materials exhibit extraordinary oxidation resistance (withstanding up to 10 ppm chlorine exposure) and exceptional pH resilience (stable across a 1-12 pH spectrum).
Groundbreaking Anti-Fouling Surface Engineering
Our ultra-hydrophilic surface (boasting a contact angle <10°) combined with nanoparticle reinforcement slashes organic fouling by 50%, prolonging chemical cleaning intervals from 3 to 6 months and reducing maintenance expenses by 40%.
