1. Permeate flow rate and stabilized salt rejection are based on the following meticulously defined standard test conditions:
For NF membranes (2000ppm MgSO4, 0.48 MPa, 25ºC, 15% recovery), and RO membranes (2000ppm NaCl solution,
1.55 MPa, 25ºC, 15% recovery) prior to any hot water disinfection process.
2. The variation range of permeate flow is +/-15%, with the final water yield potentially fluctuating further due to

Farming Applications
Water is vital for maintaining the health of farm animals (e.g., cattle, chickens, sheep, pigs) and maximizing their productive performance. The quality of water is as crucial as its quantity in influencing desired animal growth outcomes.
Farm water can originate from diverse sources such as water wells, municipal water networks, and occasionally from rivers and other surface water sources.
With the exception of municipal network water (which contains free chlorine), other sources typically harbor a high concentration of dissolved and suspended solids as well as pathogens. Reverse osmosis technology has proven to be the most effective method for mitigating these adverse effects. Thus, contaminated farm water must undergo technological treatment to eliminate harmful substances and ensure animal safety.
Successful Cases Reference
Proshare PSI MEMBRANE: The Pinnacle of Membrane Technology Desalination RO Membrane: Revolutionizing Water Purification Serves Desalination in Pioneering Applications Cruise Ship: Setting Sail with Superior Water Solutions
Historically, the application of desalination membranes on international luxury cruise ships has been the domain of select international brands. As cruise ships traverse diverse waters, the quality of feed water, including variables like salinity and temperature, changes. Consequently, membranes must be versatile, adapting seamlessly to varying conditions while ensuring consistent, high-quality water production, thereby catering to the demanding requirements of ocean-going vessels.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes exhibited exceptional performance in both desalination efficiency and sustained water production. These advanced membranes successfully produced water of a quality that met the rigorous standards demanded by luxury cruise ships.
This outstanding achievement led to the adoption of these membranes on three additional cruise ships. Proshare's triumph in this competitive arena marks it as the first national brand to secure international luxury cruise ship orders for desalination RO membranes, setting a new benchmark in the industry.

Proshare Pioneering Breakthroughs in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our visionary team has creatively engineered a new era of reverse osmosis membranes using advanced polymer interface nano-self-assembly technology. This revolutionary approach has transcended the traditional limitations of membrane development with two groundbreaking innovations:
Ultra-Thin Separation Layer: Through the ingenious application of polymer interface nanotechnology, our team has achieved a thinning of the separation layer to a remarkable extent-three times thinner than conventional polyamide thin films (previously constrained to 100 nm). This transformative advancement dramatically boosts water flux, yielding a remarkable leap in permeability.
Enhanced Performance: The strategic incorporation of nanoparticles and specialized hydrophilic polymers has ushered in revolutionary enhancements in the membrane's hydrophilicity, anti-fouling capacity, endurance, and resistance to oxidation.
In stark contrast to traditional polyamide reverse osmosis membranes, Proshare's pioneering efforts have resulted in breakthroughs across four pivotal domains:
Self-Assembled Nanocomposite Films
By harnessing nano-scale precision control and nano-doping modification, we have crafted ultra-thin, meticulously ordered separation layers via state-of-the-art polymer interface nanotechnology, overcoming the conventional polyamide membranes' limitations in thickness uniformity and material diversity.
Elevated Water Flux and Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, we have precisely managed the functional layer thickness, achieving an impressive 3x reduction compared to traditional membranes, resulting in >3x superior water flux and a remarkable 30% reduction in energy usage.
Novel Polymer Materials with Exceptional Chemical Stability
Breaking new ground beyond polyamide, our team employs cutting-edge hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials boast outstanding oxidation resistance (withstanding 10 ppm chlorine exposure) alongside exceptional pH resilience (stable across a pH spectrum of 1-12).
Advanced Anti-Fouling Surface Engineering
The integration of a superhydrophilic surface (contact angle <10°) reinforced by nanoparticles significantly reduces the tendency for organic fouling by 50%, thereby extending chemical cleaning intervals from 3 to 6 months and reducing maintenance costs by a substantial 40%
