Proshare's extensive experience in desalination technology finds application in civil water supply for hotels and touristic resorts, where fresh water is indispensable. Our R.O. seawater and brackish water desalination solutions are designed to meet the burgeoning demands of rapidly expanding touristic regions, ensuring they have ample water capacity to thrive.
Farming Applications
Water is a fundamental component in ensuring the health and productivity of farm animals, including cattle, chickens, sheep, and pigs. While the volume of water is critical, the quality of that water plays an equally vital role in achieving optimal animal performance.
Water utilized on farms can be sourced from various origins, including water wells, civil water networks, and to a lesser extent, rivers and other surface sources.
Excluding water sourced from civil networks, which generally contains free chlorine, other sources often have elevated concentrations of dissolved and suspended solids and pathogens. Reverse osmosis has proven to be the most effective technology to mitigate these adverse effects. Contaminated farm water must undergo technological treatment to remove harmful substances, thus safeguarding the health and productivity of farm animals.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team at Proshare has ingeniously crafted a cutting-edge generation of reverse osmosis membranes using state-of-the-art polymer interface nano-self-assembly technology. This revolutionary development has shattered the constraints of traditional reverse osmosis membranes through two pivotal advancements:
Ultra-Thin Separation Layer: Leveraging the prowess of polymer interface nanotechnology, our team has triumphantly reduced the separation layer's thickness to a groundbreaking threefold thinner than the erstwhile standard polyamide thin film, previously constrained to 100 nm. This remarkable innovation elevates water flux to new heights, markedly enhancing permeability.
Enhanced Performance: With the ingenious incorporation of nanoparticles and unique hydrophilic polymers, we have ushered in groundbreaking improvements in membrane hydrophilicity, anti-fouling capacity, durability, and oxidation resistance, setting new standards in performance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation signifies breakthroughs across four fundamental aspects:
Self-Assembled Nanocomposite Films
Through the integration of nano-scale precision control and nano-doping modifications, we create ultra-thin, exquisitely ordered separation layers using polymer interface nanotechnology. This approach triumphs over the limitations of conventional polyamide membranes, ensuring superior thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By mastering the layer-by-layer self-assembly process, we meticulously control the functional layer thickness, achieving a remarkable threefold reduction compared to traditional membranes. This leap forward results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, along with ceramic-organic hybrids. These materials boast 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°, coupled with nanoparticle reinforcement, dramatically reduces organic fouling propensity by 50%, extending chemical cleaning cycles from 3 to 6 months and slashing maintenance costs by an impressive 40%.
Our unwavering commitment to excellence is evidenced by our prestigious certifications, which include: the Health & Safety Management System Certificate, the Environmental Management System Certificate, and the renowned ISO9001 Quality System Certificate, each of which reflects our dedication to maintaining the highest standards in quality and operational excellence.
