A prevalent challenge with RO membrane elements is fouling. While fouling doesn't alter the structure of RO membranes, the deposition on the membrane surface drastically diminishes its efficiency.
Proshare Anti-Fouling reverse osmosis (RO) combats fouling by using a unique hydrophilic coating on the membrane's surface, ensuring enduring and stable performance. By mitigating fouling, the need for frequent cleaning is reduced, leading to decreased operational expenditures in the water treatment facility.
Proshare Anti- Fouling is the perfect solution for processing urban sewage water destined for industrial purposes.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our visionary team has ingeniously crafted a pioneering new generation of reverse osmosis membranes, harnessing the power of polymer interface nano-self-assembly technology. This innovation triumphantly overcomes the constraints faced by traditional reverse osmosis membrane development through two groundbreaking advancements:
Ultra-Thin Separation Layer: Utilizing cutting-edge polymer interface nanotechnology, our team has remarkably reduced the thickness of the separation layer to at least a third of the traditional polyamide thin film's dimensions, previously capped at 100 nm. This leap forward dramatically boosts water flux, offering a remarkable enhancement in permeability.
Enhanced Performance: Thanks to the infusion of nanoparticles and specialized hydrophilic polymers, we have achieved unprecedented strides in augmenting the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance, setting new benchmarks for performance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation sets new standards with breakthroughs in four pivotal domains:
Self-Assembled Nanocomposite Films
Through the seamless integration of nano-scale precision control and nano-doping modification, we craft ultra-thin, intricately ordered separation layers using polymer interface nanotechnology. This novel approach transcends the limitations of conventional polyamide membranes, revolutionizing thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By meticulously optimizing the layer-by-layer self-assembly process, we've achieved precise control over functional layer thickness, slashing it to a third of traditional membranes. This innovation culminates in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Breaking away from polyamide, our team employs cutting-edge hydrophilic polymers (e.g., modified polysulfones) alongside ceramic-organic hybrids. These materials showcase extraordinary oxidation resistance (capable of withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability across a pH range of 1-12).
Anti-Fouling Surface Engineering
The creation of a superhydrophilic surface (with a contact angle of <10°) coupled with nanoparticle reinforcement drastically reduces organic fouling propensity by 50%, effectively doubling chemical cleaning cycles from 3 months to an impressive 6 months, and slashing maintenance costs by 40%.
