Our solutions extend to essential applications such as steam boiler feeding, the food and beverage industry (including mineral water bottling, soft drinks, and juices), painting lines, dairies, ice cream manufacturing, laundries, hospitals, textiles, mechanical industries, and steel companies, ensuring top-tier quality for every need.
Hospitality/Seawater and Brackish Water Desalination Applications
Proshare's extensive expertise in desalination technology is also applied to civil water desalination for hotels and tourist resorts. Freshwater supply is critical for these infrastructures, and our R.O. seawater or brackish water desalination offers an alternative solution that meets the growing capacity demands of expanding tourist areas.
Farming applications
Water quality is vital to ensuring animal well-being and achieving optimal productivity, whether for cattle, chickens, sheep, or pigs. Beyond the sheer quantity of water, its quality is equally pivotal in supporting the desired growth and performance of farm animals.
Farm water sources can be diverse, including water wells, civil water networks, and, to a lesser extent, rivers and other superficial sources, each contributing to the overall water availability on farms.
Except for water from civil networks containing free chlorine, other sources typically exhibit high levels of dissolved and suspended solids, along with pathogens. Our reverse osmosis technology has proven to be the most efficient method to mitigate these negative effects. Contaminated farm water must undergo treatment to reduce harmful substances, ensuring it is safe for animal consumption.

Proshare Trailblazing Advances by Our Team in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our team has pioneered a revolutionary new generation of reverse osmosis membranes utilizing breakthrough polymer interface nano-self-assembly technology, overcoming traditional constraints through two pivotal advancements:
Revolutionary Ultra-Thin Separation Layer: Leveraging advanced polymer interface nanotechnology, our team has impressively minimized the separation layer thickness to a mere fraction-over three times thinner than the conventional polyamide thin film, which was restricted to 100 nm. This extraordinary development dramatically boosts water flux, achieving a remarkable increase in permeability.
Superior Performance Enhancement: The infusion of nanoparticles and cutting-edge hydrophilic polymers catalyzes groundbreaking improvements in the membrane's hydrophilicity, formidable anti-fouling capability, durability, and robust oxidation resistance.
In contrast to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases strides in four critical dimensions:
Ingenious Self-Assembled Nanocomposite Films
Through the integration of nano-scale precision control and nano-doping modification, we forge ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This methodology transcends the limitations of conventional polyamide membranes regarding thickness consistency and material versatility.
Boosted Water Flux and Unprecedented Energy Efficiency
By meticulously refining the layer-by-layer self-assembly process, we masterfully control the functional layer thickness, achieving a 3x reduction compared to traditional membranes. This breakthrough culminates in an impressive >3x increase in water flux while attaining a notable 30% reduction in energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
