Hospitality/Seawater and Brackish Water Desalination Applications
Proshare's extensive expertise in desalination technology extends to providing solutions for water desalination in hotels and tourist resorts. These infrastructures depend heavily on fresh water supply. Our Reverse Osmosis (R.O.) sea water or brackish water desalination systems offer a reliable alternative to meet the growing water demands of rapidly developing tourist areas.
Farming applications
Water is vital to ensuring the health and optimal performance of livestock, including cattle, chickens, sheep, and pigs. The quality of water-not just its quantity-plays a critical role in promoting livestock growth and productivity.
Farms procure water from various sources such as wells, municipal water supplies, and less frequently, rivers or other surface sources.
Except for municipal water networks containing free chlorine, other water sources often exhibit high levels of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology stands out as the most effective method for mitigating these negative effects, ensuring the farm water undergoes treatment to remove harmful substances for the animals.

Proshare Unveiling the Team's Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our talented team at Proshare has brilliantly pioneered a cutting-edge generation of reverse osmosis membranes, leveraging the marvels of polymer interface nano-self-assembly technology. This groundbreaking development transcends the limitations of conventional reverse osmosis membranes, presenting two monumental advancements:
Revolutionary Ultra-Thin Separation Layer: Through the advanced application of polymer interface nanotechnology, our team has remarkably achieved a separation layer that is at least three times thinner than the traditional polyamide thin film, previously constrained to a thickness of 100 nm. This significant reduction in thickness translates into a remarkable enhancement in water flux and a substantial leap in permeability.
Boosted Performance: By incorporating nanoparticles and bespoke hydrophilic polymers, we've realized revolutionary improvements in the membrane's hydrophilicity, anti-fouling capability, durability, and resistance to oxidation.
In comparison to conventional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation underscores breakthroughs in four pivotal areas:
Ingenious Self-Assembled Nanocomposite Films
By mastering nano-scale precision and the integration of nano-doping modification, we fabricate ultra-thin, highly ordered separation layers utilizing polymer interface nanotechnology. This sophisticated approach surmounts traditional polyamide membranes' challenges concerning thickness uniformity and material diversity.
Enhanced Water Flux and Unmatched Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we've precisely refined the functional layer thickness, achieving an impressive 3x reduction compared to traditional membranes. This precision engineering results in over 3x heightened water flux and a 30% dip in energy consumption.
Innovative Polymer Materials Boasting Superior Chemical Stability
Transcending conventional polyamide, we utilize state-of-the-art hydrophilic polymers, such as modified polysulfones, alongside ceramic-organic hybrids. These pioneering materials demonstrate outstanding resistance to oxidation (withstanding exposure to 10 ppm chlorine) and exceptional pH tolerance (maintaining stability across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
The cutting-edge superhydrophilic surface, with a contact angle less than 10°, synergized with nanoparticle reinforcement, curtails organic fouling propensity by an impressive 50%. This innovation extends chemical cleaning cycles from 3 to 6 months and slashes maintenance costs by 40%.
Our unwavering commitment to excellence is underscored by our industry-leading certifications: Health & Safety Management System Certificate, Environmental Management System Certificate, and the prestigious ISO9001 Quality System Certificate.
