Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our visionary team has ingeniously pioneered an advanced generation of reverse osmosis membranes. Leveraging cutting-edge polymer interface nano-self-assembly technology, we have transcended traditional development constraints with two remarkable innovations:
Ultra-Thin Separation Layer: Utilizing state-of-the-art polymer interface nanotechnology, our team has achieved an extraordinary feat by reducing the separation layer's thickness to an impressive threefold thinner than customary polyamide thin films (previously restricted to 100 nm). This innovation dramatically elevates water flux, resulting in a significant leap in permeability.
Enhanced Performance: By integrating cutting-edge nanoparticles and tailor-made hydrophilic polymers, we have made revolutionary advancements in the membrane's hydrophilicity, anti-fouling capability, as well as its durability and oxidation resistance.
When compared to conventional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation showcases remarkable advancements across four pivotal aspects:
Self-Assembled Nanocomposite Films
Employing nano-scale precision control and nano-doping modification, we have engineered ultra-thin, highly organized separation layers through polymer interface nanotechnology. This methodology challenges and surpasses the limitations of conventional polyamide membranes in terms of both thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through the meticulous optimization of our layer-by-layer self-assembly process, the functional layer's thickness is precisely manipulated, achieving a remarkable 3x reduction compared to traditional membranes. This breakthrough culminates in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Advancing beyond polyamide, we employ cutting-edge hydrophilic polymers such as modified polysulfones and innovative ceramic-organic hybrids. These materials demonstrate exceptional oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability across a pH range of 1-12).
Anti-Fouling Surface Engineering
Our superhydrophilic surface (boasting a contact angle of <10°) fortified with nanoparticle reinforcement, dramatically decreases the propensity for organic fouling by 50%. This advancement extends chemical cleaning cycles from 3 months to an impressive 6 months, while simultaneously reducing maintenance costs by 40%.
