Farming applications

Water is indispensable for maintaining the health and vigor of livestock such as cattle, chickens, sheep, and pigs, essential for achieving optimum animal productivity. Both the quantity and quality of water are critical to their desirable growth.
Farm water supplies can originate from various sources, including water wells, civil water networks, and, to a lesser extent, rivers and other surface sources.
Excluding chlorine-treated water from civil networks, other water sources often contain high concentrations of dissolved and suspended solids and pathogens. Reverse osmosis technology stands out as the most effective solution to mitigate these adverse effects. Consequently, farm water should undergo advanced technological treatment to remove harmful substances, safeguarding animal health and productivity.

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 was reserved for select global brands. As cruise ships voyage through varying waters, with fluctuations in salinity and temperature, membranes must adeptly adjust to these diverse conditions while reliably maintaining water production that meets the high demands of ocean-going vessels.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes showcased exceptional performance in both desalination rate and consistent water output. The superior quality water produced by these membranes conformed to the stringent standards required by luxury cruise liners.
This extraordinary achievement precipitated the replacement of desalination membranes on three additional cruise ships, marking Proshare as the pioneering national brand to secure international luxury cruise ship contracts for desalination RO membranes.

Our Advantages

Proshare Pioneering the Future: Breakthroughs by Our Team in Advanced Reverse Osmosis Membrane Technology
Proshare Our innovative team has masterfully developed an advanced generation of reverse osmosis membranes utilizing cutting-edge polymer interface nano-self-assembly technology. This breakthrough triumphs over the conventional limitations of traditional reverse osmosis membranes with two transformative advancements:
Ultra-Thin, High-Efficiency Separation Layer: Through advanced polymer interface nanotechnology, our team has succeeded in reducing the separation layer to an unprecedented thinness, achieving at least three times the reduction compared to conventional polyamide films (formerly capped at 100 nm). This revolutionary enhancement significantly boosts water flux, leading to remarkable improvements in permeability.
Enhanced Membrane Performance: The groundbreaking incorporation of nanoparticles and specialized hydrophilic polymers has dramatically advanced the membrane's properties, including unmatched hydrophilicity, superior anti-fouling capability, enhanced durability, and robust oxidation resistance.
When compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases remarkable breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films
By harnessing nano-scale precision control and nano-doping modification, we create ultra-thin and highly ordered separation layers using advanced polymer interface nanotechnology. This innovative approach transcends the boundaries of conventional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Optimized Energy Efficiency
By meticulously refining the layer-by-layer self-assembly process, we precisely control the functional layer thickness, achieving a remarkable threefold reduction compared to traditional membranes. This leads to a more than threefold increase in water flux and a significant 30% reduction in energy consumption.
Revolutionary Polymer Materials with Exceptional Chemical Stability
Moving beyond the limitations of polyamide, our team utilizes state-of-the-art hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These advanced materials exhibit outstanding oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and extensive pH tolerance (consistently stable across a 1-12 pH range).
Cutting-Edge Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, coupled with nanoparticle reinforcement, reduces organic fouling propensity by an impressive 50%. This extension pushes chemical cleaning cycles from 3 months to an incredible 6 months, thereby slashing maintenance costs by 40%.
