Farming applications

Water is crucial in ensuring the health and productivity of farm animals, such as cattle, chickens, sheep, and pigs. Both the quantity and quality of water are vital in achieving optimal growth and performance, making water treatment essential for successful farming operations.
On farms, water is sourced from a variety of origins-water wells, civil water networks, and occasionally from rivers and other surface sources. Each source's unique profile demands tailored treatment to meet the needs of the farm.
Excluding water from civil networks (which contains free chlorine), other sources often present high levels of dissolved solids, suspended impurities, and pathogens. Reverse osmosis technology emerges as the leading solution to mitigate these negative impacts. Contaminated farm water should undergo specialized treatment to reduce harmful substances, thereby ensuring a safe and productive environment for animals.

Successful Cases Reference

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
Traditionally, the realm of desalination membranes on international luxury cruise ships was ruled by a few international giants. Given that the salinity and temperature of feed water fluctuate with the ship's journey, these membranes must adapt seamlessly to changing conditions, ensuring consistent water production to meet the demands of ocean-going luxury vessels.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes have outperformed expectations, delivering exceptional desalination rates and stable water production. These membranes produce water that adheres to the high standards set by luxury cruise ships.
Thanks to these outstanding results, three more cruise ships have opted to replace their membranes with Proshare's products. This triumph marks Proshare as the first national brand to secure international luxury cruise ship orders for desalination RO membranes.

Our Advantages

Proshare Team's Groundbreaking Leap in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our visionary team has exceptionally pioneered a state-of-the-art generation of reverse osmosis membranes, harnessing cutting-edge polymer interface nano-self-assembly technology. This has shattered the boundaries of conventional reverse osmosis membrane development with two revolutionary advancements:
Ultra-Thin, High-Performance Separation Layer: Leveraging advanced polymer interface nanotechnology, our team has achieved a remarkable reduction in separation layer thickness, now at least three times thinner than the conventional polyamide thin film (historically constrained to 100 nm). This monumental breakthrough dramatically boosts water flux, offering substantial enhancements in permeability.
Revolutionized Performance: By introducing innovative nanoparticles and uniquely engineered hydrophilic polymers, we've initiated groundbreaking developments in the membrane's hydrophilicity, anti-fouling capacity, enhanced durability, and superior oxidation resistance.
In stark contrast to traditional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation achieves unprecedented breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films of the Future
Through the fusion of nano-scale precision control with advanced nano-doping modification, we've been able to craft ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This novel method triumphs over the traditional polyamide membrane limitations in thickness uniformity and material versatility.
Enhanced Water Flux and Exceptional Energy Efficiency
By refining the intricate layer-by-layer self-assembly technique, the functional layer thickness is expertly managed, resulting in a 3x reduction when compared to standard membranes. The outcome is >3x enhanced water flux coupled with a notable 30% reduction in energy consumption.
Pioneering Polymer Materials with Unrivaled Chemical Stability
Surpassing the limitations of polyamide, our team employs advanced hydrophilic polymers such as modified polysulfones and innovative ceramic-organic hybrids. These materials exhibit remarkable oxidation resistance (capable of enduring 10 ppm chlorine exposure) and outstanding pH tolerance (maintaining stability across a broad pH range of 1-12).
Next-Generation Anti-Fouling Surface Engineering
With a superhydrophilic surface (contact angle <10°) fortified by nanoparticle reinforcement, organic fouling is significantly reduced by 50%. This innovation extends chemical cleaning intervals from 3 months to 6 months and slashes maintenance expenditures by 40%.
