Industry Applications
Proshare Proshare has accumulated an invaluable wealth of experience by delivering cutting-edge technical solutions to the industrial sector, where the demand for absolutely pure water is paramount for various industrial processes, including wastewater treatment, resource recycling, and reuse.
Our expertise spans a multitude of key industry sectors, encompassing petrochemical, mining, lithium extraction from salt lakes, lithium iron phosphate & lithium battery recycling, semiconductors, seawater desalination, reclaimed water, leachate treatment, synthetic biology, copper foil manufacturing, pharmaceuticals, and power generation.
Furthermore, our technologies cater to diverse applications such as steam boiler feeding, food & beverage processing (mineral water bottling, soft drinks, juices), painting lines, dairies, ice cream production, laundries, hospitals, textile industries, mechanical industries, and steel companies, among others.
Hospitality/Seawater and Brackish Water Desalination Applications
Leveraging Proshare's extensive experience in desalination technology, we also offer advanced solutions for water desalination tailored for civil use in hotels and touristic resorts. As fresh water is indispensable for these infrastructures, our R.O. seawater or brackish water desalination systems provide a viable alternative to meet the growing water demands of rapidly expanding touristic areas.
Farming applications
Water quality is pivotal to ensuring optimal animal health and productivity on farms, whether it be for cattle, chickens, sheep, or pigs. Not only does the quantity of water matter, but its quality is crucial to achieving the desired growth and performance of livestock.
Farm water sources can vary widely, originating from water wells, civil water networks, and, to a lesser extent, rivers and other surface sources. Each source presents unique challenges that must be addressed.
Excluding water from civil networks (which contain free chlorine), other water sources often harbor high levels of dissolved and suspended solids, as well as pathogens. Reverse osmosis technology has proven to be the most efficient method to mitigate these negative effects. Contaminated farm water should undergo thorough technological treatment to remove harmful substances, safeguarding the well-being of livestock.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our cutting-edge team has ingeniously crafted an avant-garde generation of reverse osmosis membranes, leveraging the pioneering polymer interface nano-self-assembly technology. This groundbreaking approach surmounts the constraints faced by traditional membrane development through two pivotal advancements:
a. Ultra-Thin Separation Layer: Harnessing the revolutionary polymer interface nanotechnology, we have astoundingly minimized the separation layer's thickness to achieve an astounding thinness three times finer than the conventional polyamide thin films, which were previously confined to a 100 nm threshold. This monumental breakthrough leads to a remarkable boost in water flux, resulting in an unparalleled enhancement of permeability.
b. Enhanced Performance: The integration of cutting-edge nanoparticles alongside specialized hydrophilic polymers has precipitated transformative leaps in the membrane's hydrophilicity, anti-fouling properties, robustness, and resilience against oxidation.
Compared to traditional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation showcases significant advancements across four critical dimensions:
Self-Assembled Nanocomposite Films
Through meticulous nano-scale precision control and the innovative nano-doping modification, we sculpt ultra-thin, exquisitely ordered separation layers via polymer interface nanotechnology. This sophisticated technique triumphs over the traditional polyamide membranes' challenges of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly process, the functional layer's thickness is expertly governed, achieving a remarkable 3x reduction when measured against traditional membranes. This optimization translates to over 300% greater water flux and a significant 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Evolving beyond the limits of polyamide, our team employs advanced hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids, renowned for their extraordinary resilience to oxidation (capable of withstanding an exposure of 10 ppm chlorine) and remarkable pH durability (stable across a pH spectrum of 1-12).
Anti-Fouling Surface Engineering
The superhydrophilic surface, characterized by a contact angle of less than 10°, combined with robust nanoparticle reinforcement, dramatically reduces the tendency for organic fouling by an impressive 50%. This innovation extends the intervals for chemical cleaning from a frequency of every 3 months to an efficient 6-month cycle, resulting in a substantial 40% decrease in maintenance costs.
