A common challenge facing RO membrane elements is the issue of fouling, which can impact efficiency. While fouling does not alter the structural integrity of RO membrane elements, the presence of foulant on the membrane surface can drastically impair its performance.
Proshare Anti-Fouling reverse osmosis (RO) actively prevents fouling through the application of a unique and exclusive hydrophilic coating on the membrane surface. This innovative technology ensures long-term stable operation. By minimizing fouling, the frequency of required cleanings is significantly reduced, ultimately contributing to a lower overall operational expenditure (OPEX) at the water treatment facility.
Proshare Anti- Fouling is expertly designed to meet your needs in treating urban sewage water, especially for industrial applications, providing a robust and efficient solution.

Farming applications
Water is a crucial component in ensuring optimal health and productivity of farm animals such as cattle, chickens, sheep, and pigs. The quantity and quality of water play vital roles in achieving the desired growth and performance of these animals, highlighting the importance of superior water management.
Within farming environments, water sources are diverse, ranging from wells, civil water networks, to a lesser extent, rivers, and other superficial sources. Each source presents unique challenges and opportunities for effective water management.
Excluding water from civil networks, which contains free chlorine, other water sources typically have elevated levels of dissolved and suspended solids, as well as pathogens. Reverse osmosis technology emerges as the most effective solution to mitigate these adverse effects. It is imperative that contaminated farm water undergo technological treatment to minimize harmful substances, safeguarding the wellbeing and productivity of the animals.

Proshare Pioneering Breakthroughs in Next-Gen Reverse Osmosis Membrane Technology
Proshare Our dedicated team has ingeniously pioneered a revolutionary new class of reverse osmosis membranes utilizing cutting-edge polymer interface nano-self-assembly technology. With this state-of-the-art approach, we have transcended the constraints of conventional membrane development through two pivotal advancements:
Ultra-Thin Separation Layer Mastery: Leveraging the sophisticated polymer interface nanotechnology, we have achieved an unprecedented reduction in the separation layer's thickness, crafting a layer at least three times thinner than the conventional polyamide thin film (which was historically limited to 100 nm). This monumental achievement significantly boosts water flux, ushering in a new era of enhanced permeability.
Unmatched Performance Enhancement: Through the strategic incorporation of nanoparticles alongside specialized hydrophilic polymers, we have realized groundbreaking progress in enhancing the membrane's hydrophilicity, anti-fouling capabilities, durability, and remarkable oxidation resistance.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's pioneering innovation signifies breakthroughs across four pivotal domains:
Self-Assembled Nanocomposite Films Innovation
By seamlessly integrating nano-scale precision control and nano-doping modification, we craft ultra-thin, highly ordered separation layers through advanced polymer interface nanotechnology. This sophisticated methodology overcomes the traditional limitations of polyamide membranes related to thickness uniformity and material versatility.
Enhanced Water Flux and Energy Efficiency Revolution
Through meticulous optimization of the layer-by-layer self-assembly process, we precisely control the functional layer's thickness, achieving a remarkable 3x reduction in comparison to traditional membranes. This innovation results in >3x enhanced water flux and a 30% reduction in energy consumption.
Novel Polymer Materials with Unparalleled Chemical Stability
Moving beyond traditional polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, alongside ceramic-organic hybrids. These innovative materials exhibit exceptional resilience against oxidation (withstanding exposure to chlorination levels up to 10 ppm) and superb pH tolerance (remaining stable within a wide pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
Our superhydrophilic surface design (with a contact angle of less than 10°) is fortified with nanoparticle reinforcement, leading to a 50% reduction in organic fouling tendency.
