Industry Applications
Proshare Proshare Innovation Suzhou Co., Ltd. has garnered invaluable expertise by delivering cutting-edge technical solutions to the industrial sector. Here, the demand for impeccably pure water is critical across diverse industrial processes, including wastewater treatment, resource recycling, and reuse.
We actively engage with leading industry sectors such as petrochemical, mining, lithium extraction from salt lake, lithium iron phosphate & lithium battery recycling, semiconductor, seawater desalination, reclaimed water, leachate treatment, synthetic biology, copper foil production, pharmaceuticals, and power generation.
Our solutions extend to steam boiler feed water, food and beverage industries (including mineral water bottling, soft drinks, and juices), painting lines, dairies, ice cream production, laundries, hospitals, textiles, mechanical industries, and steel companies, among others.
Hospitality/Seawater and Brackish Water Desalination Applications
Proshare's extensive expertise in desalination technology is also applied to provide sustainable water solutions for civil use in hotels and tourist resorts. The availability of fresh water is vital for such infrastructures, and our Reverse Osmosis (R.O.) desalination of seawater or brackish water offers an ideal alternative. It meets the growing capacity needs and increasing water demands of rapidly expanding tourist destinations.
Farming applications
Water is indispensable in ensuring the optimal health and productivity of livestock, such as cattle, chickens, sheep, and pigs. Beyond just quantity, the quality of water plays a crucial role in achieving desired growth and performance levels in animals.
Farms utilize water from diverse sources, including water wells, civil water networks, and, to a lesser extent, rivers and other surface sources. It's essential to ensure water quality for the well-being of farm animals.
Excluding water from civil networks, which contains free chlorine, other sources often harbor high concentrations of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective method to mitigate these adverse effects. Contaminated farm water must undergo technological treatment to reduce harmful substances, ensuring animal health and productivity.

Proshare Revolutionary Breakthrough in Advanced Reverse Osmosis Membrane Technology
Proshare team has pioneered the development of a cutting-edge generation of reverse osmosis membranes utilizing polymer interface nano-self-assembly technology. This innovation masterfully addresses the limitations of conventional reverse osmosis membranes by achieving remarkable breakthroughs in two pivotal domains:
Ultra-Thin Separation Layer: Through the ingenious application of polymer interface nanotechnology, our team has impressively managed to decrease the separation layer's thickness to at least one-third of the traditional polyamide thin film, which was previously confined to 100 nm. This remarkable feat dramatically boosts water flux and leads to a significant enhancement in permeability.
Enhanced Performance: The strategic incorporation of nanoparticles alongside specialized hydrophilic polymers has resulted in revolutionary advancements in the membrane's hydrophilicity, anti-fouling capability, robustness, and oxidation resistance.
Compared to conventional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation showcases breakthroughs across four key dimensions:
Self-Assembled Nanocomposite Films
By seamlessly integrating nano-scale precision control with nano-doping modification, we create ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This sophisticated method transcends the conventional polyamide membranes' constraints in thickness uniformity and material versatility.
Enhanced Water Flux and Energy Efficiency
With an optimized layer-by-layer self-assembly process, the functional layer's thickness is meticulously regulated, achieving an impressive 3x reduction compared to traditional membranes. The outcome is >3x higher water flux and 30% lower energy consumption.
Innovative Polymer Materials with Superior Chemical Stability
Surpassing traditional polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials boast outstanding oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (remaining stable in a pH range of 1-12).
Anti-Fouling Surface Engineering
The superhydrophilic surface (contact angle <10°), reinforced with nanoparticles, minimizes organic fouling propensity by 50%, effectively doubling the chemical cleaning cycles from 3 months to 6 months, while reducing maintenance costs by 40%.
