1. To achieve optimal performance standards, the permeate flow rate and stabilized salt rejection are established based on the following rigorously tested standard conditions:
NF membrane (2000ppm MgSO4, 0.48 MPa, 25ºC, 15% recovery), RO membrane (2000ppm NaCl solution,
1.55 MPa, 25ºC, 15% recovery) prior to any hot water disinfection.
2. It is important to note that the permissible variation range of permeate flow is +/-15%. Additionally, the final water yield may experience further fluctuations due to
the heat treatment process involved in ensuring superior performance.

Farming Applications
Ensuring optimal animal health and productivity in farming sectors including cattle, chickens, sheep, and pigs, hinges on the quality as much as the availability of water. Delivering top-tier water quality is essential in fostering desirable growth trajectories and maximizing animal performance.
Farm water is sourced from diverse origins such as wells, civil water networks, and sometimes rivers or other surface waters, each presenting unique characteristics.
Apart from chlorine-treated civil network waters, other sources often carry elevated levels of dissolved solids, suspensions, and pathogens. Reverse osmosis technology emerges as the quintessential solution to reducing these impurities. It is vital for farm water, particularly from non-civil origins, to undergo technologically advanced treatments to eradicate harmful substances, safeguarding the health and vitality of animals.

ProshareTeam's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
ProshareOur visionary team has achieved a pioneering breakthrough in the realm of reverse osmosis membranes. By leveraging the cutting-edge prowess of polymer interface nano-self-assembly technology, we have shattered the conventional barriers of membrane development with two transformative advancements:
Ultra-Thin Separation Layer: Through the intricate deployment of polymer interface nanotechnology, our experts have crafted an extraordinarily thin separation layer, at least three times thinner than conventional polyamide thin films that were previously confined to a thickness of 100 nm. This revolutionary thinning significantly boosts water flux, resulting in dramatically enhanced permeability.
Enhanced Performance: By ingeniously integrating nanoparticles with specially designed hydrophilic polymers, we have achieved significant advancements in the enhancement of the membrane's hydrophilicity, anti-fouling properties, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes,Proshare's innovation is truly transformative, as it demonstrates groundbreaking advancements across four critical aspects:
Self-Assembled Nanocomposite Films
The exquisite blend of nano-scale precision control with nano-doping modification guides the creation of ultra-thin, perfectly ordered separation layers via polymer interface nanotechnology. This revolutionary method overcomes the limitations of thickness uniformity and material diversity faced by conventional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
By meticulously refining the layer-by-layer self-assembly process, we have expertly controlled the functional layer thickness, achieving an exceptional 3x reduction compared to traditional membranes. This strategic advancement leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Stepping beyond polyamide, our research team deftly employs advanced hydrophilic polymers (such as modified polysulfones) and innovative ceramic-organic hybrids. These state-of-the-art materials exhibit superior oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (stabilizing within a pH range of 1-12).
Anti-Fouling Surface Engineering
Our ultra-hydrophilic surface, designed with a contact angle of less than 10° and reinforced by nanoparticle infusion, diminishes the likelihood of organic fouling by 50%. This innovation extends chemical cleaning cycles from 3 months to 6 months, while dramatically reducing maintenance costs by 40%.
