A frequent issue with RO membrane elements is fouling, which can impede performance. While fouling does not alter the structural integrity of RO membrane elements, the deposition of foulants on the membrane surface can drastically diminish its operational efficacy.
Proshare Anti-Fouling reverse osmosis (RO) mitigates fouling by utilizing an innovative hydrophilic coating on the membrane surface, ensuring prolonged stable operation. By minimizing fouling, this leads to reduced cleaning frequency, thereby decreasing operational expenditure (OPEX) in water treatment plants over time.
Proshare Anti- Fouling is engineered to fulfill your requirements for treating urban sewage water tailored for industrial applications.

Farming applications
Water is vital to ensure the optimal health of farm animals, such as cattle, chickens, sheep, and pigs, and to maximize their productive performance. It's not just the quantity, but the quality of water that plays a pivotal role in promoting desired growth and health.
Farm water sources can be diverse, ranging from water wells and civil water networks to, less commonly, rivers and other surface sources.
With the exception of civil network water, which typically contains free chlorine, other sources often have high levels of dissolved or suspended solids and pathogens. Reverse osmosis technology emerges as the superior method for mitigating these detrimental effects. Contaminated farm water should be treated with advanced technologies to minimize harmful substances, thus safeguarding animal health.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare At the forefront of innovation, our team has pioneered a revolutionary advancement in reverse osmosis membranes by employing cutting-edge polymer interface nano-self-assembly technology, surmounting the confines of traditional membrane development with two groundbreaking enhancements:
Ultra-Thin Separation Layer: Leveraging the sophistication of polymer interface nanotechnology, our team has achieved a monumental reduction in the separation layer thickness, now an impressive threefold thinner than conventional polyamide thin films. This leap forward magnificently boosts water flux, heralding a considerable leap in permeability.
Enhanced Performance: Through the integration of nanoparticles and unique hydrophilic polymers, we have realized stellar advancements in the membrane's hydrophilicity, anti-fouling capabilities, robustness, and resistance to oxidation.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation sets new benchmarks with breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films
By harnessing nano-scale precision and nano-doping modification, we craft ultra-thin and meticulously ordered separation layers through polymer interface nanotechnology, effectively transcending the constraints of conventional polyamide membranes in uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, we precisely control the functional layer thickness, achieving a remarkable 3x reduction compared to traditional membranes. This astonishing feat results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing the limitations of polyamide, we employ advanced hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These novel materials exhibit extraordinary oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability across a 1-12 pH range).
Anti-Fouling Surface Engineering
Our cutting-edge superhydrophilic surface, with a contact angle of less than 10°, combined with nanoparticle reinforcement, significantly diminishes organic fouling by 50%. This advance extends chemical cleaning cycles from 3 months to a remarkable 6 months, reducing maintenance costs by an impressive 40%.
