For NF membrane (2000ppm MgSO4, 0.48 MPa, 25ºC,15% recovery), and RO membrane (2000ppm NaCl solution,

1.55 MPa, 25ºC,15% recovery) prior to any hot water disinfection procedures.

2. Note that the variation range of permeate flow is +/-15%, with the final water yield potentially fluctuating further due to

the intricacies of the heat treatment process.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare The Proshare team has triumphantly pioneered a revolutionary new generation of reverse osmosis membranes. Using cutting-edge polymer interface nano-self-assembly technology, they have transcended the traditional limitations of reverse osmosis membrane development through two remarkable advancements:
Ultra-Thin Separation Layer: Utilizing the power of advanced polymer interface nanotechnology, the team has achieved an extraordinary feat by making the separation layer at least three times thinner than traditional polyamide thin films. This unprecedented breakthrough not only significantly boosts water flux but also greatly enhances permeability.
Enhanced Performance: By introducing innovative nanoparticles and specialized hydrophilic polymers, Proshare has realized transformative advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance, setting new standards in the industry.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases significant breakthroughs in four critical areas:
Self-Assembled Nanocomposite Films
With the fusion of nano-scale precision control and nano-doping modification, Proshare has engineered ultra-thin, exquisitely ordered separation layers through polymer interface nanotechnology. This innovative approach effectively overcomes the conventional polyamide membranes' constraints in thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, the precision control of the functional layer thickness is achieved, leading to an impressive 3x reduction compared to traditional membranes. This accomplishment results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Moving beyond the limitations of polyamide, Proshare employs state-of-the-art hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These advanced materials demonstrate outstanding oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability across a 1-12 pH range).
Anti-Fouling Surface Engineering
The combination of a superhydrophilic surface (with a contact angle of less than 10°) and nanoparticle reinforcement effectively reduces organic fouling propensity by 50%, extending chemical cleaning cycles from 3 to 6 months and slashing maintenance costs by a remarkable 40%.
