Farming applications

Water is a vital component in ensuring the health and productivity of farm animals like cattle, chickens, sheep, and pigs. However, it is not just the quantity but also the quality of the water that influences optimal animal growth and performance.
On farms, water sources can be diverse, including water wells, municipal water networks, and, to a lesser degree, rivers and other surface sources, each impacting the water quality differently.
Except for treated municipal water (containing free chlorine), other sources often present high concentrations of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology has proven to be the most effective solution to mitigate these issues, ensuring that farm water is adequately treated to remove harmful substances, safeguarding animal health and productivity.

Successful Cases Reference

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
Historically, international luxury cruise ships have relied on a select few global brands for desalination membranes. As cruise ships navigate diverse waters, from salty seas to temperate currents, the feed water's salinity and temperature vary. Our membranes excel in adapting to these changes, ensuring consistently stable water production that meets the demanding requirements of these ocean vessels.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes have exceeded expectations, showcasing unparalleled performance in desalination rates and maintaining stable water output. The water produced by these innovative membranes aligns perfectly with the rigorous quality standards demanded by luxury cruise ships.
This outstanding achievement prompted the replacement of desalination membranes on three more cruise ships, establishing Proshare as a trailblazer, the first national brand to secure international orders for luxury cruise ship desalination RO membranes.

Our Advantages

Proshare Pioneering Breakthroughs in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously crafted a revolutionary new generation of reverse osmosis membranes utilizing polymer interface nano-self-assembly technology, surpassing the constraints of traditional membrane development through two pivotal advancements:
Ultra-Thin Separation Layer: By harnessing the power of polymer interface nanotechnology, our team has reduced the thickness of the separation layer to a remarkable three times thinner than conventional polyamide thin films (formerly restricted to 100 nm). This groundbreaking innovation substantially enhances water flux, delivering significant improvements in permeability.
Enhanced Performance: Through the incorporation of nanoparticles and specially designed hydrophilic polymers, we've achieved remarkable advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovation sets new standards in four key areas:
Self-Assembled Nanocomposite Films
Utilizing nano-scale precision control alongside nano-doping modification, we create ultra-thin, highly ordered separation layers through polymer interface nanotechnology, overcoming the limitations of conventional polyamide membranes in terms of thickness uniformity and material diversity.
Boosted Water Flux and Energy Efficiency
Through the optimization of the layer-by-layer self-assembly process, we precisely control the functional layer thickness, achieving a 3x reduction compared to traditional membranes. This results in >3x elevated water flux and 30% reduction in energy consumption.
Innovative Polymer Materials with Outstanding Chemical Stability
Moving beyond the bounds of polyamide, our team employs advanced hydrophilic polymers (like modified polysulfones) and ceramic-organic hybrids. These groundbreaking materials exhibit exceptional oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (remaining stable across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
The superhydrophilic surface (contact angle <10°), reinforced with nanoparticles, reduces the propensity for organic fouling by 50%, doubling the chemical cleaning cycle from 3 to 6 months and reducing maintenance costs by 40%.
