Hospitality/Seawater and Brackish Water Desalination Applications
Proshare's extensive experience in desalination technology is also leveraged in supplying water for civil use in hotels and tourist resorts. Freshwater is crucial for these infrastructures, and our RO seawater or brackish water desalination solutions are tailored to meet the expanding needs of these burgeoning tourist locations with their escalating water demands.
Farming applications
Water quality is vital for ensuring the well-being of farm animals like cattle, chickens, sheep, and pigs, facilitating optimal performance and productive growth. The quality of water holds as much significance as the quantity when it comes to nurturing these animals.
Farm water can originate from multiple sources, such as water wells, civil water networks, and to a lesser extent, rivers and other superficial sources.
Apart from water from civil networks (which contains free chlorine), other sources are typically laden with high concentrations of dissolved and suspended solids, along with pathogens. Reverse osmosis technology stands as the most effective method to mitigate the adverse effects of contaminants. Consequently, water utilized on farms should undergo advanced treatment to minimize harmful substances that could affect the animals.
Municipal and Civil use
We offer pioneering and scalable solutions to our customers, ensuring efficient and sustainable treatment of wastewater and effluents. Our expansive array of patented technologies, alongside national-level experts and scientific research institutions, guarantee peace of mind for municipalities striving to meet stringent health and environmental standards.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our innovative Proshare team has triumphantly developed a revolutionary new generation of reverse osmosis membranes. This cutting-edge advancement is rooted in polymer interface nano-self-assembly technology, allowing us to overcome the traditional constraints of reverse osmosis membrane development through two pivotal breakthroughs:
Ultra-Thin Separation Layer: Leveraging state-of-the-art polymer interface nanotechnology, our pioneering team has achieved a remarkable reduction in the separation layer's thickness, making it at least three times thinner than the conventional polyamide thin films, which were previously confined to a 100 nm limit. This monumental breakthrough significantly boosts water flux, leading to a dramatic enhancement in permeability.
Enhanced Performance: By introducing cutting-edge nanoparticles and specialized hydrophilic polymers, we have achieved groundbreaking advancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance. This ensures a superior and long-lasting performance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation marks significant breakthroughs in four critical aspects:
Self-Assembled Nanocomposite Films
Through the integration of nano-scale precision control alongside nano-doping modification, we have created ultra-thin and highly ordered separation layers using polymer interface nanotechnology. This innovative approach overcomes the challenges of conventional polyamide membranes by enhancing thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By optimizing the layer-by-layer self-assembly process, we have precisely controlled the functional layer thickness, achieving an impressive 3x reduction when compared to traditional membranes. This breakthrough results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing the limitations of polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, and innovative ceramic-organic hybrids. These materials offer exceptional oxidation resistance (capable of withstanding 10 ppm chlorine exposure), and pH tolerance (maintaining stability across a 1-12 pH range).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, is reinforced with nanoparticles to reduce organic fouling propensity by 50%. This innovation extends chemical cleaning cycles from 3 months to 6 months, significantly lowering maintenance costs by 40%.
