Hospitality/Seawater and Brackish Water Desalination Applications
Leveraging Proshare's extensive expertise in desalination technology, we offer unrivaled solutions for water desalination, specifically tailored for civil use in hotels and touristic resorts. Freshwater supply is critical for these infrastructures, and our R.O. seawater or brackish water desalination systems are the ideal alternative to meet the growing capacities and burgeoning water demands of rapidly expanding touristic areas.
Farming applications
Water is indispensable for ensuring the health and productivity of livestock such as cattle, chickens, sheep, and pigs. It's not just the quantity of water that matters; the quality is equally important to achieve optimal animal growth and performance.
On farms, water may be sourced from a variety of origins, including water wells, civil water networks, and occasionally rivers or other superficial sources.
Excluding water derived from civil networks, which often contains free chlorine, other sources typically exhibit high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has emerged as the most effective means to mitigate these adverse effects, ensuring that water used in farms undergoes the necessary technological treatments to remove harmful substances for livestock.

Proshare The Team's Pioneering Advances in Next-Gen Reverse Osmosis Membrane Technology
Proshare Our innovative team has masterfully crafted a cutting-edge generation of reverse osmosis membranes, leveraging polymer interface nano-self-assembly technology. This groundbreaking development shatters the constraints of conventional reverse osmosis membrane design through two remarkable advancements:
Ultra-Thin Separation Layer: Through the sophisticated application of polymer interface nanotechnology, our team has achieved a monumental reduction in the thickness of the separation layer-now at least three times thinner than the conventional 100 nm polyamide thin films. This incredible breakthrough drastically boosts water flux, markedly advancing permeability.
Enhanced Performance: Infusing the membrane with nanoparticles and specialized hydrophilic polymers has revolutionized its hydrophilicity, anti-fouling properties, durability, and resistance to oxidation, setting new standards in membrane performance.
In stark contrast to traditional polyamide reverse osmosis membranes, Proshare's innovation manifests breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films
The integration of nano-scale precision control and nano-doping modification has led to the production of ultra-thin, highly ordered separation layers via advanced polymer interface nanotechnology. This innovative approach transcends the limitations of traditional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we achieve precise functional layer thickness control, resulting in a remarkable 3x reduction compared to traditional membranes. This advancement delivers over three times greater water flux and a 30% reduction in energy consumption.
Innovative Polymer Materials with Unmatched Chemical Stability
Surpassing traditional polyamide, our team employs state-of-the-art hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials offer extraordinary oxidation resistance (enduring up to 10 ppm chlorine exposure) and pH tolerance (stable across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
Featuring a superhydrophilic surface with a contact angle of less than 10°, coupled with nanoparticle fortification, our technology reduces organic fouling propensity by 50%. This extends chemical cleaning cycles from 3 months to 6 months and slashes maintenance costs by 40%.
