Our Advantages

Proshare A Trailblazing Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare The Proshare team has innovatively pioneered an extraordinary leap in reverse osmosis membranes, utilizing cutting-edge polymer interface nano-self-assembly technology. This groundbreaking innovation surmounts the limitations posed by traditional reverse osmosis membrane development by achieving two pivotal advancements:
Ultra-Thin Separation Layer: Through the remarkable application of polymer interface nanotechnology, the team has astoundingly reduced the separation layer's thickness to a mere fraction-at least three times thinner than traditional polyamide thin films, previously constrained to a 100 nm threshold. This revolutionary achievement dramatically amplifies water flux, resulting in a profound enhancement of permeability.
Enhanced Performance: The strategic introduction of nanoparticles alongside specialized hydrophilic polymers has sparked transformative advancements in the membrane's hydrophilicity. It also substantially boosts anti-fouling capacity, durability, and resistance to oxidation, setting new benchmarks in performance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation shines with remarkable breakthroughs across four key dimensions:
Self-Assembled Nanocomposite Films
By seamlessly merging nano-scale precision control with nano-doping modifications, Proshare expertly crafts ultra-thin, highly ordered separation layers via advanced polymer interface nanotechnology. This innovative method triumphs over the constraints of conventional polyamide membranes, enhancing both thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, the functional layer thickness is expertly controlled, leading to a remarkable 3x reduction compared to conventional membranes. This precise control translates into >3x higher water flux and a remarkable 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Transcending traditional polyamide constraints, the team employs cutting-edge hydrophilic polymers, such as modified polysulfones, combined with ceramic-organic hybrids. These innovative materials boast extraordinary oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (demonstrating stability across a wide pH range of 1-12).
Anti-Fouling Surface Engineering
The integration of a superhydrophilic surface (with a contact angle <10°), reinforced by nanoparticles, effectively diminishes organic fouling propensity by 50%. This innovative engineering extends chemical cleaning cycles from 3 to 6 months, substantially reducing maintenance costs by 40%, thus ensuring long-term efficiency and cost-effectiveness.
