Additionally, our solutions cater to steam boilers, food & beverages (mineral water bottling, soft drinks, juices), painting lines, dairy production, ice cream manufacturing, laundries, hospitals, textile, mechanical industries, steel companies, and more.
Hospitality/Seawater and Brackish Water Desalination Applications
Proshare's extensive experience in desalination technology is also applied in water desalination for civil use in hotels and touristic resorts. Fresh water supply is crucial, and Proshare offers Reverse Osmosis (R.O.) solutions for seawater or brackish water desalination, efficiently meeting the growing water demands of rapidly expanding tourist areas.
Farming applications
Water is a fundamental element to ensure the well-being of farm animals (such as cattle, chickens, sheep, pigs) and optimize their performance. The quality, not just the quantity, of water plays a pivotal role in achieving the desired growth and health of these animals.
Farm water sources can vary, originating from wells, civil water networks, and occasionally from rivers and other superficial sources, each with distinct characteristics.
Except for water from civil networks that contains free chlorine, other sources often have high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective solution for mitigating these adverse effects. Contaminated water on farms must undergo technological treatment to minimize harmful substances for animals.

Proshare A Leap Forward: Our Team's Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our dedicated team at Proshare has trailblazed the development of a new era of reverse osmosis membranes, ingeniously leveraging polymer interface nano-self-assembly technology. We have triumphantly surpassed the constraints of traditional membrane technologies with two groundbreaking advancements:
Pioneering Ultra-Thin Separation Layer: With the embrace of polymer interface nanotechnology, our team has successfully minimized the thickness of the separation layer to an astonishingly slim measure, at least three times thinner than the traditional polyamide thin films, which were previously restricted to 100 nm. This revolutionary achievement dramatically boosts water flux, ensuring a marked enhancement in permeability.
Revolutionized Performance: By integrating nanoparticles with specialized hydrophilic polymers, we have set groundbreaking standards in improving the membrane's hydrophilicity, anti-fouling capabilities, durability, and resistance to oxidation.
When compared to conventional polyamide reverse osmosis membranes, Prosharestands out with its pioneering breakthroughs in four crucial areas:
Innovative Self-Assembled Nanocomposite Films
Through the fusion of nano-scale precision control with nano-doping modification, we craft ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This innovative approach triumphs over the traditional polyamide membranes' challenges in achieving thickness uniformity and material variety.
Superior Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly process, the thickness of the functional layer is meticulously controlled, achieving a remarkable 3x reduction compared to traditional membranes. The outcome is >3x the water flux alongside a 30% reduction in energy consumption.
Advanced Polymer Materials with Unmatched Chemical Stability
Surpassing the realms of polyamide, our experts utilize cutting-edge hydrophilic polymers, such as modified polysulfones and ceramic-organic hybrids. These materials exhibit outstanding oxidation resistance (withstanding up to 10 ppm chlorine exposure) and impressive pH tolerance (maintaining stability across a pH range of 1-12).
Sophisticated Anti-Fouling Surface Engineering
The ultra-superhydrophilic surface, boasting a contact angle of less than 10°, combined with nanoparticle reinforcement, significantly curtails organic fouling by 50%. This innovation extends the frequency of chemical cleaning cycles from 3 to 6 months, slashing maintenance costs by an impressive 40%.
