A prevalent issue with RO membrane elements is fouling. While fouling does not alter the inherent structure of RO membrane elements, it significantly diminishes performance by accumulating foulants on the membrane surface.
Proshare Anti-Fouling reverse osmosis (RO) effectively combats fouling by employing a proprietary hydrophilic coating on the membrane surface. This treatment ensures long-term, stable operation. By minimizing fouling, cleaning frequency is reduced, significantly lowering operating expenses (OPEX) in water treatment facilities.
The Proshare Anti- Fouling membrane is expertly designed to meet your urban sewage water treatment needs for industrial applications.

Farming applications
Water is crucial for ensuring the optimal health and productivity of farm animals, such as cattle, chickens, sheep, and pigs. While the quantity of water is vital, its quality is equally important in influencing desired growth and performance outcomes.
The water used in farming operations may originate from various sources, including water wells, civil water networks, and, to a lesser extent, rivers and other surface sources. Ensuring the purity and quality of this water is paramount for the health and productivity of livestock.
Outside of civil networks, which contain free chlorine, other water sources often have high levels of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology has proved to be the most effective method for mitigating these contaminants. It's imperative that farm water undergoes technological treatment to reduce harmful substances, safeguarding animal health and well-being.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our innovative team at Proshare has masterfully developed a pioneering new generation of reverse osmosis membranes. Utilizing cutting-edge polymer interface nano-self-assembly technology, this advancement surmounts the limitations of traditional methods with two critical breakthroughs:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, our team has successfully achieved a remarkable reduction in the separation layer's thickness, making it at least three times thinner than traditional polyamide thin films, which were previously capped at 100 nm. This transformation vastly enhances the water flux, leading to notable improvements in permeability.
Enhanced Performance: By integrating nanoparticles and specialized hydrophilic polymers, we have ushered in groundbreaking advancements, elevating the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance to new heights.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases remarkable breakthroughs across four pivotal aspects:
Self-Assembled Nanocomposite Films
Through the meticulous integration of nano-scale precision control and nano-doping modification, we craft ultra-thin, impeccably ordered separation layers using polymer interface nanotechnology. This trailblazing approach addresses and surpasses the limitations of conventional polyamide membranes, especially in terms of thickness consistency and material diversity.
Enhanced Water Flux and Energy Efficiency
By meticulously refining the layer-by-layer self-assembly process, we precisely control the functional layer thickness, achieving a significant 3x reduction compared to traditional membranes. This results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Expanding beyond the traditional polyamide, we employ advanced hydrophilic polymers-such as modified polysulfones-and ceramic-organic hybrids. These pioneering materials offer extraordinary oxidation resistance (capable of enduring 10 ppm chlorine exposure) and pH tolerance (remaining stable across a 1-12 pH spectrum).
Anti-Fouling Surface Engineering
Our superhydrophilic surface engineering, characterized by a contact angle of less than 10° and reinforced by nanoparticles, effectively reduces the tendency for organic fouling by an impressive 50%. This extends chemical cleaning cycles from 3 months to 6 months, simultaneously slashing maintenance costs by a substantial 40%.
