A prevalent challenge faced by RO membrane elements is fouling, impacting efficiency. While the inherent structure of RO membrane elements remains unaltered, the accumulation of fouling agents on the surface can cause a substantial decline in performance.
Proshare Anti-Fouling reverse osmosis (RO) system effectively prevents fouling through an innovative and exclusive hydrophilic coating applied to the membrane surface, ensuring prolonged, stable operation. By minimizing fouling, the frequency of necessary cleanings is reduced, ultimately lowering operational expenditure (OPEX) at the water treatment facility.
Proshare Anti- Fouling is expertly designed to meet your requirements for purifying urban sewage water for industrial applications.

Farming applications
Water quality is paramount to ensuring the health and optimal performance of farm animals such as cattle, chickens, sheep, and pigs. The quality of water, not just its quantity, plays a critical role in the animals' growth and overall productivity.
Farm water sources can be diverse, ranging from water wells and civil water networks to rivers and other surface sources. Each source demands careful management to ensure the health of livestock.
Water sourced from civil networks often contains free chlorine, while other sources typically have elevated levels of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology has proven to be the most effective method to mitigate these challenges. It is crucial that contaminated farm water undergoes technological treatment to minimize harmful substances, safeguarding animal health.

Proshare Revolutionary Team Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare has pioneered the development of a next-generation reverse osmosis membrane using state-of-the-art polymer interface nano-self-assembly technology, surmounting the challenges of traditional membrane development with two pivotal innovations:
Ultra-Thin Separation Layer Innovation: By utilizing polymer interface nanotechnology, the team has remarkably reduced the separation layer's thickness to just a third of the conventional polyamide thin film (formerly constrained to 100 nm). This monumental leap dramatically boosts water flux, resulting in significantly enhanced permeability.
Elevated Performance Beyond Limits: The incorporation of nanoparticles and unique hydrophilic polymers has catalyzed extraordinary advancements in the membrane's hydrophilicity, anti-fouling proficiency, durability, and oxidation resistance.
Compared to conventional polyamide reverse osmosis membranes, Proshare's innovation epitomizes groundbreaking progress in four crucial domains:
Self-Assembled Nanocomposite Films Mastery
The convergence of nano-scale precision control and nano-doping modification facilitates the formation of ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This method triumphs over the constraints of traditional polyamide membranes in terms of thickness uniformity and material versatility.
Enhanced Water Flux and Energy Efficiency Revolution
Through meticulous optimization of the layer-by-layer self-assembly process, the functional layer thickness is expertly controlled, leading to a threefold reduction compared to conventional membranes. This advancement results in over three times greater water flux and a notable 30% reduction in energy consumption.
Revolutionary Polymer Materials with Unmatched Chemical Stability
Venturing beyond polyamide, the team employs cutting-edge hydrophilic polymers (such as modified polysulfones) and innovative ceramic-organic hybrids. These materials showcase remarkable resistance to oxidation (withstanding 10 ppm chlorine exposure) and broad pH stability (remaining stable across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (with a contact angle <10°) coupled with nanoparticle enhancement substantially reduces organic fouling likelihood by 50%, extending chemical cleaning cycles from 3 to 6 months and slashing maintenance costs by 40%
