Farming Applications

Water is crucial for ensuring the health and optimal productivity of farm animals, such as cattle, chickens, sheep, and pigs. It's not just the quantity but also the quality of water that impacts their growth. Ensuring superior water quality is essential for achieving the best performance in animal husbandry.
Farm water sources vary, including water wells, civil water networks, and, to a lesser degree, rivers and other surface sources, offering flexibility and adaptability for farming operations.
Excluding chemically treated civil network water (with free chlorine), other sources typically contain high levels of dissolved and suspended solids and pathogens. Reverse osmosis stands as the most effective technology to mitigate these adverse effects, ensuring farm water undergoes advanced treatment to remove harmful substances, thus safeguarding animal health.

Successful Cases Reference

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
The application of desalination membranes on international luxury cruise ships has historically been dominated by a few international brands. These membranes must excel in adapting to varying water conditions, including salinity and temperature fluctuations, encountered during voyages. It is vital they ensure reliable and consistent water production to satisfy the demands of ocean-going vessels.
PSI MEMBRANE Pro-HR-SW seawater desalination membranes have set a new benchmark, offering exemplary desalination rates alongside unparalleled stable water production. They have successfully met the rigorous water quality standards required by luxury cruise ships.
This outstanding achievement resulted in the replacement of desalination membranes on three additional cruise ships. Proshare's pioneering success in this endeavor heralds it as the first national brand to secure orders for desalination RO membranes from international luxury cruise lines.

A Complete Water Treatment Plant for Generating Ultra-pure Water in the Semiconductor Industry

In the realm of electronic-grade ultra-pure water, the standards for membrane desalination rates are exceptionally high, and only a select few brands can meet these stringent demands.
Leveraging Proshare's groundbreaking TFN membrane technology in conjunction with the TsingXi team's extensive expertise in water treatment, a comprehensive water treatment plant solution was devised.

Our Advantages

Proshare's Remarkable Excellence Team's Breakthrough in Pioneering the Future of Reverse Osmosis Membrane Technology
Proshare's Unyielding Innovation Our dedicated team at Proshare has masterfully crafted a groundbreaking new generation of reverse osmosis membranes utilizing cutting-edge polymer interface nano-self-assembly technology. This paradigm-shifting development has successfully shattered the constraints of traditional reverse osmosis membrane design through two pivotal advancements:
Revolutionary Ultra-Thin Separation Layer: Leveraging advanced polymer interface nanotechnology, our team has triumphantly reduced the separation layer's thickness to a striking one-third of the conventional polyamide thin film's dimensions (previously restrained to 100 nm). This remarkable advancement dramatically amplifies water flux, heralding a notable leap in permeability.
Performance Elevated to New Heights: The strategic infusion of nanoparticles and specialized hydrophilic polymers has ushered in extraordinary enhancements in the membrane's hydrophilicity, anti-fouling prowess, durability, and oxidation resistance.
When juxtaposed with conventional polyamide reverse osmosis membranes, Proshare's ingenious innovation showcases breakthroughs across four cardinal dimensions:
Self-Assembled Nanocomposite Films of Superior Quality
Through the incorporation of nano-scale precision control and nano-doping modification, we have crafted ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This revolutionary approach transcends the traditional polyamide membranes' limitations in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Unmatched Energy Efficiency
Through the refined optimization of the layer-by-layer self-assembly process, the thickness of the functional layer is precisely controlled, delivering a dramatic 3x reduction compared to standard membranes. This results in >3x amplified water flux alongside a commendable 30% reduction in energy consumption.
Innovative Polymer Materials with Unparalleled Chemical Stability
Surpassing the confines of polyamide, our team employs state-of-the-art hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials boast remarkable oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH resilience (maintaining stability across a 1-12 pH range).
Advanced Anti-Fouling Surface Engineering
The engineered superhydrophilic surface (with a contact angle of less than 10°) reinforced by nanoparticles effectively reduces organic fouling potential by a remarkable 50%, doubling the chemical cleaning cycles from 3 months to an impressive 6 months, and slashing maintenance costs by 40%.
