Our Advantages

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our dedicated team has made a groundbreaking leap forward by ingeniously crafting a revolutionary generation of reverse osmosis membranes. Leveraging state-of-the-art polymer interface nano-self-assembly technology, Proshare has conquered the constraints that have traditionally hampered reverse osmosis membrane advancement with two pivotal innovations:
Ultra-Thin Separation Layer: Harnessing the power of cutting-edge polymer interface nanotechnology, our experts have successfully diminished the separation layer's thickness to a mere fraction - at least three times thinner than the conventional polyamide thin film's 100 nm benchmark. This monumental achievement not only propels water flux to new heights but also delivers a remarkable leap in permeability efficiency.
Enhanced Performance: By pioneering the integration of nanoparticles alongside specialized hydrophilic polymers, Proshare has achieved a transformative leap in the membrane's attributes. This includes unparalleled hydrophilicity, exceptional anti-fouling prowess, increased durability, and robust oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation boasts remarkable progress across four pivotal domains:
Self-Assembled Nanocomposite Films
Through the synergy of nano-scale precision control and nano-doping modification, we have crafted ultra-thin, impeccably ordered separation layers via polymer interface nanotechnology. This advanced approach shatters the barriers of conventional polyamide membranes in terms of thickness uniformity and material versatility, forging new paths in membrane technology.
Enhanced Water Flux and Energy Efficiency
By masterfully optimizing the layer-by-layer self-assembly process, the functional layer's thickness is meticulously controlled, marking a threefold reduction compared to traditional membranes. This revolutionary refinement culminates in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond polyamide, our team harnesses advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These cutting-edge materials showcase exceptional oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability across a 1-12 pH range).
Anti-Fouling Surface Engineering
Our superhydrophilic surface (contact angle <10°), fortified with nanoparticle reinforcement, slashes organic fouling propensity by half, doubling chemical cleaning cycles from 3 months to an impressive 6 months, and reducing maintenance costs by a substantial 40%.
