Hospitality/Seawater and Brackish Water Desalination Applications
Proshare's extensive expertise in desalination technology is also applied to water desalination in the hospitality sector, particularly for civil use in hotels and tourist resorts. Fresh water provisioning is crucial for these infrastructures, and our R.O. seawater or brackish water desalination systems offer an alternative solution that meets the growing demand in rapidly expanding tourist areas, ensuring adequate water supply.
Farming Applications
Water is vital for maintaining animal health and optimizing their productive performance, whether cattle, chickens, sheep, or pigs. It's not only the quantity but also the quality of water that significantly impacts animal growth and productivity.
The farm's water supply can originate from diverse sources, including wells, civil water networks, and, to a lesser extent, rivers and superficial sources. We emphasize that water from civil networks often contains free chlorine, while other sources may have high levels of dissolved and suspended solids and pathogens. Therefore, reverse osmosis technology stands out as the most effective solution, minimizing harmful substances in water used on farms to protect animal health.
Eliminating contaminants in water from non-civil sources is crucial. Reverse osmosis technology emerges as the superior method for mitigating the negative effects of high concentrations of dissolved solids and pathogens. Our state-of-the-art treatment processes ensure that water used on farms is safe and conducive to optimal animal growth and health.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our Proshare team has brilliantly pioneered a new era of reverse osmosis membranes, leveraging cutting-edge polymer interface nano-self-assembly technology. We've shattered the boundaries of traditional membranes with two significant enhancements:
Ultra-Thin Separation Layer: Through the innovative use of polymer interface nanotechnology, our team has remarkably reduced the separation layer's thickness to an unparalleled level, now at least three times slimmer than the conventional polyamide thin film. This exceptional breakthrough notably boosts water flux, delivering a remarkable enhancement in permeability.
Enhanced Performance: By integrating nanoparticles and uniquely designed hydrophilic polymers, we have achieved transformative progress in enhancing the membrane's hydrophilicity, anti-fouling properties, durability, and oxidation resistance-setting new standards in membrane performance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation marks breakthroughs across four pivotal areas:
Self-Assembled Nanocomposite Films
By combining nano-scale precision control with advanced nano-doping modification, we fabricate ultra-thin, highly ordered separation layers using polymer interface nanotechnology. This avant-garde method surpasses the conventional constraints of polyamide membranes in both thickness uniformity and material versatility.
Enhanced Water Flux and Energy Efficiency
With optimized layer-by-layer self-assembly techniques, we precisely manage the thickness of the functional layer, achieving an astonishing threefold reduction compared to traditional membranes. This advancement results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Our forward-thinking approach goes beyond polyamide, employing sophisticated hydrophilic polymers like modified polysulfones and ceramic-organic hybrids. These materials offer extraordinary oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (maintains stability in a wide pH range from 1 to 12).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, bolstered by nanoparticle reinforcement, minimizes organic fouling by 50%, effectively extending chemical cleaning cycles from 3 to 6 months and reducing maintenance expenses by 40%.
Our esteemed certifications include: Health & Safety Management System Certificate, Environmental Management System Certificate, and the renowned ISO 9001 Quality System Certificate, ensuring our commitment to excellence and reliability in every aspect of our process.
We pride ourselves on our cutting-edge innovations, backed by the Invention Patent of Membranes Production and the Invention Patent of Multi-Layer RO Membrane, reflecting our dedication to pioneering advanced technology.
