As these infrastructures grow, our R.O. seawater or brackish water desalination solutions ensure a consistent supply of fresh water, meeting the escalating demands of expanding tourist areas.
Farming applications
Water is crucial not only for the vitality and fitness of farm animals such as cattle, chickens, sheep, and pigs but also for achieving optimal performance in livestock production. The quality of water is equally as vital as the quantity available to influence the desired growth and productivity of the animals.
Water used on farms can originate from diverse sources including water wells, civil water networks, and to a lesser degree, rivers and other surface sources.
Excluding water from civil networks (which often includes free chlorine), other sources are typically high in dissolved and suspended solids and pathogens. Reverse osmosis technology emerges as the most effective method to mitigate these detrimental effects. Contaminated farm water must undergo technological treatment to reduce harmful substances, safeguarding animal health and productivity.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our pioneering team has ingeniously engineered a state-of-the-art generation of reverse osmosis membranes. Using cutting-edge polymer interface nano-self-assembly technology, we have shattered the traditional boundaries of reverse osmosis membrane development. Our remarkable advancement is underscored by two groundbreaking enhancements:
Ultra-Thin Separation Layer: By leveraging the pinnacle of polymer interface nanotechnology, our team has triumphantly achieved a separation layer that is astonishingly three times thinner than the conventional polyamide thin film, previously constrained to a 100 nm thickness. This exceptional breakthrough dramatically elevates water flux, culminating in a remarkable surge in permeability.
Enhanced Performance: Through the innovative integration of nanoparticles and specialized hydrophilic polymers, our membranes now boast unprecedented advancements in hydrophilicity, anti-fouling prowess, durability, and oxidation resistance, setting new industry standards.
When juxtaposed with traditional polyamide reverse osmosis membranes, Proshare's trailblazing innovation reveals unmatched achievements across four pivotal domains:
Self-Assembled Nanocomposite Films
The precise convergence of nano-scale precision control and nano-doping modification empowers the formation of ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This inventive approach dismantles the conventional limitations of polyamide membranes regarding thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through the meticulous refinement of the layer-by-layer self-assembly process, the functional layer thickness is expertly controlled, achieving an astounding 3x reduction compared to traditional membranes. This refinement leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing the confines of polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, and innovative ceramic-organic hybrids. These avant-garde materials exhibit extraordinary oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability across a pH range of 1-12).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, combined with potent nanoparticle reinforcement, slashes organic fouling propensity by 50%. It extends chemical cleaning intervals from 3 months to a remarkable 6 months, driving maintenance costs down by 40%.
