A typical challenge with RO membrane elements is fouling. While fouling doesn't alter the structural integrity of RO membranes, the accumulation of foulants on the membrane surface can notably diminish performance.
Proshare Anti-Fouling reverse osmosis (RO) combats fouling with the application of a unique hydrophilic coating on the membrane surface. This ensures long-lasting stable operation and by thwarting fouling, it minimizes cleaning frequency, significantly reducing the operational expenditure (OPEX) at water treatment plants.
Proshare Anti- Fouling perfectly caters to your needs for treating urban sewage water destined for industrial application.

Farming applications
Access to high-quality water is crucial for the health and productivity of livestock such as cattle, chickens, sheep, and pigs. The water quality, alongside its quantity, plays a fundamental role in promoting optimal growth and performance of animals.
Farm water supplies can originate from various sources, including water wells, civil water networks, and, to a lesser extent, rivers and other surface sources. Ensuring water quality is imperative to maintain animal health and productivity.
Excluding water from civil networks (which contains free chlorine), other sources typically possess high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most efficient method to mitigate these contaminants, providing essential purification of farm water to protect animal health and well-being.

Proshare Revolutionary Leap in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has made pioneering strides in crafting a new era of reverse osmosis membranes through cutting-edge polymer interface nano-self-assembly. This advancement transcends the traditional constraints of reverse osmosis membrane development with two monumental breakthroughs:
Ultra-Thin Separation Layer: Utilizing state-of-the-art polymer interface nanotechnology, we've achieved a remarkable feat by slimming down the separation layer to a revolutionary thinness-three times leaner than the conventional polyamide films, previously confined to 100 nm. This astonishing reduction elevates water flux, thus greatly boosting permeability.
Superior Performance: The infusion of nanoparticles alongside specialized hydrophilic polymers has ushered in unprecedented enhancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and resilience against oxidation.
When compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases breakthroughs across four crucial dimensions:
Self-Assembled Nanocomposite Films
Through the amalgamation of nano-scale precision control with nano-doping modifications, we've conjured ultra-thin, highly uniform separation layers, thanks to polymer interface nanotechnology. This strategy surpasses the conventional polyamide membranes in achieving consistent thickness and material diversity.
Improved Water Flux and Energy Efficiency
By perfecting the layer-by-layer self-assembly process, we ensure meticulous control over the functional layer thickness, achieving a staggering 3x reduction compared to traditional membranes. This innovation delivers >3x higher water flux and 30% reduced energy consumption.
Innovative Polymer Materials with Exceptional Chemical Robustness
Breaking free from polyamide constraints, we harness advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials boast outstanding resistance to oxidation (withstanding exposure to 10 ppm chlorine) and tolerance to pH variations (maintaining stability across a pH range of 1 to 12).
Advanced Anti-Fouling Surface Engineering
With a superhydrophilic surface (boasting a contact angle of <10°) augmented by nanoparticle enhancement, we've halved the propensity for organic fouling, extending chemical cleaning cycles from 3 to 6 months and slashing maintenance expenses by 40%.
