1. For optimal performance, please consider that permeate flow rate and stabilized salt rejection are determined based on meticulously tested standard conditions as follows:
NF membrane (2000ppm MgSO4, 0.48 MPa, 25ºC, 15% recovery), RO membrane (2000ppm NaCl solution,
1.55 MPa, 25ºC, 15% recovery) before any hot water disinfection process.
2. We kindly remind you that the permeate flow variation range is +/-15%, and the final water yield may encounter further fluctuations due to
the integral heat treatment procedures involved.

For optimal animal health and productivity (including cattle, chickens, sheep, and pigs), water quality is as crucial as its availability. Ensuring high-quality water is pivotal in influencing desired growth and maximizing animal performance.
Farm water can originate from various sources such as water wells, municipal water networks, and sometimes from rivers and other surface sources, each possessing unique characteristics.
Apart from chlorine-treated municipal network water, other sources often contain high levels of dissolved and suspended solids and pathogens. Therefore, reverse osmosis technology is the most effective method to reduce these contaminants. It is crucial for farm water, especially from non-municipal sources, to undergo technological treatment to reduce harmful substances, ensuring the safety and well-being of the animals.

ProshareTeam's Groundbreaking Leap in Advanced Reverse Osmosis Membrane Technology
ProshareOur visionary team has made a pioneering breakthrough with the development of avant-garde reverse osmosis membranes. Utilizing the transformative power of polymer interface nano-self-assembly technology, we have successfully surmounted the conventional barriers encountered in traditional membrane development through two extraordinary advances:
Revolutionary Ultra-Thin Separation Layer: Through the masterful application of polymer interface nanotechnology, our team has engineered a separation layer that is remarkably at least three times thinner than standard polyamide thin films, which were previously limited to 100 nm. This groundbreaking reduction in thickness significantly boosts water flux, resulting in a remarkable enhancement in permeability.
Enhanced Membrane Performance: By incorporating nanoparticles along with specially designed hydrophilic polymers, we have achieved unprecedented advancements in elevating the membrane's hydrophilicity, anti-fouling capabilities, longevity, and resistance to oxidation.
When compared to traditional polyamide reverse osmosis membranes,Proshare's innovation delivers breakthroughs across four critical dimensions:
Self-Assembled Nanocomposite Films
The integration of nano-scale precision control with nano-doping modification facilitates the creation of ultra-thin, carefully ordered separation layers via polymer interface nanotechnology. This groundbreaking method surpasses the limitations in thickness uniformity and material diversity seen in conventional polyamide membranes.
Enhanced Water Flux and Optimum Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, we have precisely calibrated the functional layer thickness, achieving an astounding 3x reduction compared to traditional membranes. This strategic advancement results in more than 3x the water flux and 30% reduced energy consumption.
Innovative Polymer Materials with Superior Chemical Stability
Departing from polyamide, our team utilizes advanced hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These state-of-the-art materials exhibit superior oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH resilience (maintaining stability within the 1-12 pH range).
Advanced Anti-Fouling Surface Engineering
Our ultra-hydrophilic surface, designed with a contact angle less than 10° and reinforced by nanoparticles, reduces the likelihood of organic fouling by 50%. This innovation extends chemical cleaning cycles from 3 months to 6 months, while cutting maintenance costs by 40%.
