Industry Applications
Proshare Proshare Innovation Suzhou Co., Ltd. has garnered invaluable expertise by delivering cutting-edge technical solutions to industries that demand the highest purity water. This involves critical processes such as wastewater treatment, reuse, and resource recycling-each designed to meet the rigorous demands of modern industrial applications.
Our expertise spans a diverse array of industry sectors including petrochemical, mining, lithium extraction from salt lakes, lithium iron phosphate and lithium battery recycling, semiconductor manufacturing, seawater desalination, reclaimed water treatment, leachate management, synthetic biology, copperfoil production, pharmaceuticals, and power generation.
Our solutions also extend to a wide range of sectors, such as steam boiler feed applications, the food and beverage industry (including mineral water bottling, soft drinks, and juices), painting lines, dairy production, ice cream manufacturing, laundries, hospitals, textiles, and mechanical industries, as well as steel companies.
Hospitality/Seawater and Brackish Water Desalination Applications
Proshare's vast experience in desalination technology seamlessly translates to providing water desalination solutions for civil applications in hotels and touristic resorts. As these infrastructures expand, fresh water supply becomes essential. Our R.O. seawater and brackish water desalination options offer a reliable solution, meeting the urgent and growing water demands of burgeoning touristic regions.
Farming applications
Water is a critical component for ensuring the health and optimal productivity of farm animals, including cattle, chickens, sheep, and pigs. While the quantity is important, the water's quality plays a vital role in maximizing the animals' growth and overall performance.
Farm water is sourced from various origins, such as water wells, municipal networks, and to a lesser extent, rivers and other surface sources. Each source requires careful consideration to ensure water quality meets farm standards.
Except for water from municipal networks (which contains free chlorine), other sources often contain high concentrations of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology has proven to be the most efficient method to mitigate these negative impacts, ensuring farm water undergoes treatment to remove harmful substances and safeguard animal health.

Proshare A Pioneering Leap: Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our innovative team has developed a cutting-edge generation of reverse osmosis membranes utilizing polymer interface nano-self-assembly technology. This revolutionizes traditional membrane development through two groundbreaking advancements:
Ultra-Thin Separation Layer: Leveraging advanced polymer interface nanotechnology, we've achieved a remarkable reduction in the separation layer's thickness, making it at least three times thinner than the conventional polyamide thin film, which was previously confined to 100 nm. This innovation dramatically boosts water flux, leading to significant improvements in permeability.
Enhanced Performance: The strategic inclusion of nanoparticles and specialized hydrophilic polymers has resulted in transformative improvements in the membrane's hydrophilicity, robust anti-fouling capabilities, heightened durability, and superior oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovations shine through in four pivotal areas of excellence:
Self-Assembled Nanocomposite Films
Through nano-scale precision control and nano-doping modification, we create ultra-thin, highly ordered separation layers via polymer interface nanotechnology. This method triumphs over the limitations in thickness uniformity and material diversity seen in conventional polyamide membranes.
Superior Water Flux and Energy Efficiency
Refining the layer-by-layer self-assembly process allows for precise control of the functional layer thickness, achieving a remarkable 3x reduction compared to conventional membranes. This advancement delivers >3x higher water flux alongside a 30% reduction in energy consumption.
Revolutionary Polymer Materials with Enhanced Chemical Stability
Going beyond polyamide, our team employs leading-edge hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids, offering exceptional oxidation resistance (withstanding up to 10 ppm chlorine exposure) and impressive pH tolerance (maintaining stability across a pH range of 1-12).
State-of-the-Art Anti-Fouling Surface Engineering
The superhydrophilic surface (contact angle <10°), fortified with nanoparticle reinforcement, dramatically reduces the tendency for organic fouling by 50%, extending chemical cleaning cycles from 3 to 6 months and slashing maintenance costs by 40%.
