Hospitality/Seawater and Brackish Water Desalination Applications
Proshare's extensive experience in desalination technology is also applied to water desalination for civil use in hotels and touristic resorts. Ensuring a fresh water supply is vital for these infrastructures, and Reverse Osmosis (R.O.) for seawater or brackish water desalination provides an effective alternative solution. This method meets the growing needs of rapidly expanding touristic areas and their heightened water demands.
Farming Applications
Water is crucial to ensure the well-being and optimal performance of livestock such as cattle, chickens, sheep, and pigs. However, it's not just the volume of water that is significant, but also its quality, which can greatly influence the desired growth and productivity of animals.
In farming, water can be sourced from a variety of origins, including wells, civil water networks, and, to a lesser extent, rivers and other surface sources. Each source plays a critical role in supporting agricultural operations.
Excluding water from civil networks (with free chlorine content), other sources typically have high levels of dissolved and suspended solids and pathogens. Consequently, reverse osmosis technology has proven to be the most effective method to mitigate the negative impacts. Contaminated water in farms should undergo technological treatment to diminish harmful substances, safeguarding animal health.

Proshare: Pioneering Innovation Revolutionary Team Achievements in Reverse Osmosis Membrane Innovation
Proshare: Leading the Charge Our team at Proshare has ingeniously crafted a groundbreaking generation of reverse osmosis membranes. Utilizing advanced polymer interface nano-self-assembly technology, we have surmounted traditional development barriers with two remarkable breakthroughs:
Ultra-Thin Separation Layer for Unmatched Efficiency: By harnessing the power of polymer interface nanotechnology, our team has achieved an unparalleled reduction in the separation layer's thickness-up to three times slimmer than the conventional 100 nm polyamide thin film. This innovation markedly boosts water flux, driving a significant leap in permeability.
Performance Elevated to New Heights: The fusion of nanoparticles with specialized hydrophilic polymers has catalyzed exceptional improvements in the membrane's hydrophilicity, anti-fouling capacity, durability, and oxidation resilience.
In comparison to conventional polyamide reverse osmosis membranes, Proshare'sbreakthrough represents advancements in four pivotal areas:
Self-Assembled Nanocomposite Films: A Game-Changer
Through the integration of nano-scale precision control and nano-doping modification, we create ultra-thin, highly organized separation layers via polymer interface nanotechnology. This innovative method overcomes the constraints of traditional polyamide membranes concerning thickness uniformity and material spectrum.
Enhanced Water Flux and Unparalleled Energy Efficiency
By fine-tuning the layer-by-layer self-assembly process, we achieve precise functional layer thickness control, reducing it by threefold compared to traditional membranes. This results in increased water flux by over three times and a 30% decrease in energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
Breaking away from polyamide, we employ cutting-edge hydrophilic polymers, such as modified polysulfones, along with ceramic-organic hybrids. These materials deliver outstanding resistance to oxidation (withstanding exposure to 10 ppm chlorine) and extraordinary pH resilience (remaining stable across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, synergizes with nanoparticle reinforcement to reduce organic fouling by 50%. This innovation extends chemical cleaning cycles from 3 to 6 months, slashing maintenance costs by 40%.
