1. Permeate flow rate and stabilized salt rejection are determined based on the following precise standard test conditions:
Using 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 procedures.
2. The allowable variation range of permeate flow is +/-15%. Note that the final water yield may experience further fluctuations due to
the implementation of the heat treatment process.

Farming applications
Water is vital for ensuring the optimal health and performance of farm animals such as cattle, chickens, sheep, and pigs. The quality of water is equally crucial as its quantity, impacting the animals' growth and productivity.
Farm water sources are diverse, ranging from water wells and civil networks to rivers and surface waters. Each source plays a pivotal role in maintaining animal health and productivity.
While civil network water contains free chlorine, other sources often harbor high levels of dissolved solids and pathogens. Reverse osmosis technology stands as the premier solution to mitigate these adverse effects, ensuring contaminated farm water is treated to eliminate harmful substances.
Successful Cases Reference
Renowned Proshare PSI MEMBRANE High-Efficiency Desalination RO Membrane Expert Desalination Solutions for Luxury Cruise Ships
Historically, the application of desalination membranes on international luxury cruise ships was dominated by a select few international brands. With the cruise ships' journeys, the quality of feed water, including salinity and temperature, varies significantly. Consequently, the membranes must be adaptable to diverse conditions, ensuring consistent water production to fulfill the demands of ocean-going vessels.
PSI MEMBRANE Pro-HR-SW seawater desalination membranes exhibit exceptional performance, excelling in both desalination rate and sustained water production. These membranes produce water of superior quality that meets the rigorous standards required by luxury cruise ships.

Proshare Breakthroughs in Advanced Reverse Osmosis Membrane Technology
Proshare Our pioneering team has elevated reverse osmosis technology to new heights through the innovative application of polymer interface nano-self-assembly. This avant-garde approach has successfully surpassed the conventional boundaries of reverse osmosis membrane technology with two pivotal enhancements:
Ultra-Thin Separation Layer: Leveraging cutting-edge polymer interface nanotechnology, we've ingeniously minimized the separation layer's thickness to an unprecedented level-three times thinner than the traditional 100 nm polyamide film. This revolutionary leap propels water flux to new dimensions, achieving exceptional permeability enhancements.
Enhanced Performance: Our infusion of nanoparticles and uniquely engineered hydrophilic polymers has spearheaded remarkable advancements in membrane hydrophilicity, anti-fouling efficiency, robustness, and resistance to oxidation.
In comparison with conventional polyamide reverse osmosis membranes, Proshare's trailblazing innovation stands out by excelling in four crucial areas:
Self-Assembled Nanocomposite Films
Through the synergy of nano-scale precision control and nano-doping enhancements, we craft ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This methodology transcends the constraints of standard polyamide membranes in terms of thickness uniformity and material versatility.
Enhanced Water Flux and Energy Efficiency
By meticulously refining the layer-by-layer self-assembly protocol, we achieve precise control over functional layer thickness, slashing it to a third of its traditional counterparts. This innovation culminates in water flux more than threefold higher and a notable 30% reduction in energy consumption.
Novel Polymer Materials with Unparalleled Chemical Stability
Advancing beyond the conventional polyamide, we harness advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrid materials, which boast remarkable oxidation resistance (withstanding exposure to 10 ppm chlorine) and exceptional pH resilience (maintaining stability across a broad 1-12 pH spectrum).
Anti-Fouling Surface Engineering
The superhydrophilic surface (contact angle <10°), bolstered by nanoparticle innovation, diminishes organic fouling tendencies by half, extending chemical cleaning intervals from 3 to 6 months and reducing maintenance costs by a striking 40%.
