Hospitality/Seawater and Brackish Water Desalination Applications
Proshare's extensive experience in desalination technology is strategically applied in water desalination for civil use, particularly in hotels and tourist resorts. Recognizing the essential need for fresh water in these infrastructures, our R.O. sea water or brackish water desalination solutions meet the growing capacities and water demands of rapidly expanding tourism hubs.
Farming applications
In farming, water quality is crucial to ensure optimal fitness and performance of livestock such as cattle, chickens, sheep, and pigs. Beyond mere quantity, the water's purity significantly impacts the animals' growth and vitality.
Farm water may originate from diverse sources including water wells, civil water networks, and occasionally, rivers or other surface sources.
Except for water from civil networks (which contain free chlorine), other sources often have high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven exceptionally effective in mitigating the adverse effects of contaminated farm water, necessitating technological treatment to eliminate harmful substances for livestock.

Proshare Revolutionary Advances by Our Team in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our team has expertly innovated a groundbreaking new generation of reverse osmosis membranes, leveraging cutting-edge polymer interface nano-self-assembly technology. This advancement shatters the constraints of traditional membrane development, marked by two pivotal breakthroughs:
Exceptionally Thin Separation Layer: Through the ingenious application of polymer interface nanotechnology, our team has remarkably thinned the separation layer to less than a third of the conventional polyamide thin film (previously constrained to 100 nm). This revolutionary progress dramatically boosts water flux, markedly enhancing permeability.
Superior Performance Enhancement: The strategic incorporation of nanoparticles and specialized hydrophilic polymers has propelled substantial advancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance.
When compared to conventional polyamide reverse osmosis membranes, Proshare's innovation stands out with breakthroughs in four pivotal aspects:
Pioneering Self-Assembled Nanocomposite Films
By integrating nano-scale precision control with nano-doping modification, we craft ultra-thin, exceptionally ordered separation layers using polymer interface nanotechnology. This cutting-edge approach effectively transcends the limitations of conventional polyamide membranes, offering remarkable improvements in thickness uniformity and material diversity.
Unmatched Water Flux and Energy Efficiency
With meticulous optimization of the layer-by-layer self-assembly process, we precisely control the thickness of the functional layer, achieving a remarkable 3x reduction compared to traditional membranes. This results in an extraordinary >3x increase in water flux and a striking 30% reduction in energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
Surpassing polyamide, our team employs state-of-the-art hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These avant-garde materials exhibit unparalleled oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH resilience (maintaining stability within a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (boasting a contact angle <10°) synergized with nanoparticle reinforcement, significantly reduces organic fouling tendency by 50%. This extends the interval between chemical cleaning cycles from 3 months to an impressive 6 months, thereby slashing maintenance costs by 40%.
