A prevalent issue with RO membrane elements is fouling, which can impede optimal performance. Although fouling does not alter the structural integrity of RO membrane elements, it can significantly degrade performance by accumulating foulants on the membrane surface.
Proshare Anti-Fouling reverse osmosis (RO) prevents fouling through the application of a unique hydrophilic coating on the membrane surface. This innovation not only enables long-term stable operation but also reduces the frequency of cleaning, ultimately lowering operational expenses (OPEX) for water treatment facilities.
Proshare Anti- Fouling is perfectly tailored to meet your needs for treating urban sewage water, serving a wide range of industrial applications.

Proshare Breakthroughs in State-of-the-Art Reverse Osmosis Membrane Technology
Proshare The Proshare team has ingeniously pioneered a cutting-edge generation of reverse osmosis membranes, capitalizing on polymer interface nano-self-assembly technology. This innovative stride triumphs over the classic limitations of traditional reverse osmosis membrane development, marked by two pivotal advancements:
Ultra-Thin Separation Layer: Utilizing advanced polymer interface nanotechnology, the team has spectacularly minimized the separation layer's thickness to a staggering threefold less than conventional polyamide thin films, previously constrained to 100 nm. This breakthrough remarkably amplifies water flux, offering a monumental enhancement in permeability.
Enhanced Performance: The infusion of nanoparticles and specialized hydrophilic polymers has ushered in revolutionary improvements in the membrane's hydrophilicity, anti-fouling proficiency, durability, and oxidative resistance.
In contrast to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases remarkable advancements in four critical domains:
Self-Assembled Nanocomposite Films
The fusion of nano-scale precision control with nano-doping modification empowers the creation of ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This revolutionary method transcends the constraints of conventional polyamide membranes in thickness uniformity and material versatility.
Enhanced Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly process, the functional layer thickness is meticulously regulated, culminating in a remarkable 3x reduction relative to traditional membranes. This advancement culminates in >3x higher water flux and 30% lower energy consumption.
Innovative Polymer Materials with Unmatched Chemical Stability
Venturing beyond polyamide, the team adopts cutting-edge hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials exhibit unparalleled oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (remaining stable in the 1-12 pH range).
Anti-Fouling Surface Engineering
