Hospitality/Seawater and Brackish Water Desalination Applications
Proshare's extensive expertise in desalination technology finds application in water desalination for civil use within hotels and touristic resorts. Ensuring a reliable fresh water supply is critical for these infrastructures, and our Reverse Osmosis sea water or brackish water desalination solutions offer a robust alternative. These solutions efficiently meet the growing capacities and increasing water demands of rapidly expanding touristic areas.
Farming applications
Water plays an indispensable role in ensuring the health and vitality of farm animals such as cattle, chickens, sheep, and pigs. Our solutions optimize water quality, which is equally crucial as quantity, to drive the best performance and growth of productive animals.
The origins of farm water sources are varied, encompassing water wells, civil water networks, and, to a lesser extent, rivers and other surface sources. Each source demands careful consideration to ensure optimal quality for agricultural use.
Apart from water from civil networks (which contain free chlorine), other sources typically present high levels of dissolved and suspended solids and pathogens. Our advanced reverse osmosis technology is the most effective method for mitigating these negative effects. The contaminated water used in farms requires technological treatment to reduce substances that could be harmful to animals, ensuring their overall well-being.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our dedicated team has achieved a milestone in creating a revolutionary new generation of reverse osmosis membranes. Utilizing cutting-edge polymer interface nano-self-assembly technology, we have surpassed the barriers of traditional development through two pivotal advancements:
Ultra-Thin Separation LayerThrough the application of polymer interface nanotechnology, we have remarkably minimized the thickness of the separation layer, making it three times thinner than the conventional 100 nm polyamide films. This incredible feat significantly enhances water flux, leading to a profound increase in permeability and efficiency.
Enhanced PerformanceLeveraging the power of nanoparticles and specialized hydrophilic polymers, we have realized extraordinary improvements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and resistance to oxidation.
When compared to conventional polyamide reverse osmosis membranes, Proshare's pioneering innovation showcases advancements in four crucial areas:
Self-Assembled Nanocomposite Films
By harnessing nano-scale precision control and nano-doping modifications, we have created ultra-thin, highly ordered separation layers. This advanced process, through polymer interface nanotechnology, transcends the limitations of conventional membranes with respect to thickness uniformity and diverse material applications.
Enhanced Water Flux and Energy Efficiency
Through the meticulous refinement of the layer-by-layer self-assembly process, we precisely control the thickness of the functional layer, achieving a remarkable 3x reduction compared to conventional membranes. This advancement results in over 3x higher water flux and a 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Foregoing traditional polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These cutting-edge materials exhibit outstanding oxidation resistance (withstanding up to 10 ppm chlorine exposure) and pH tolerance (maintaining stability across a pH range of 1 to 12).
Anti-Fouling Surface Engineering
The innovation of a superhydrophilic surface (with a contact angle of less than 10°) combined with nanoparticle reinforcement remarkably minimizes organic fouling by 50%. This enhancement extends chemical cleaning cycles from 3 months to 6 months, significantly cutting maintenance costs by 40%.
