Proshare's extensive experience in desalination technology is also applied in water desalination for civil use at hotels and touristic resorts. Freshwater supply is crucial for these infrastructures, and our R.O. seawater or brackish water desalination solutions efficiently meet the rising water demands of these rapidly expanding areas.
Agricultural Applications
Water is crucial for ensuring the health and optimal performance of farm animals, such as cattle, chickens, sheep, and pigs. Both the quantity and quality of water are crucial for achieving desired growth in animals.
Farm water typically originates from various sources, such as water wells, civil water networks, and occasionally rivers or other surface sources.
Excluding water from civil networks (which contain free chlorine), other water sources often have high concentrations of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective in mitigating these issues, requiring technological treatment to reduce harmful substances in farm water, thereby protecting animal health.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our pioneering team at Proshare has taken the innovative leap to craft a new generation of reverse osmosis membranes. Leveraging the cutting-edge polymer interface nano-self-assembly technology, we have surpassed traditional reverse osmosis membrane constraints with two groundbreaking advancements:
Ultra-Thin Separation Layer: Through the application of polymer interface nanotechnology, our team has achieved an unprecedented reduction in the separation layer's thickness, making it at least three times thinner than the conventional polyamide thin film, which was constrained to 100 nm. This innovation not only dramatically increases water flux but also marks a significant leap forward in permeability enhancement.
Enhanced Performance: By integrating nanoparticles with specialized hydrophilic polymers, we have realized monumental progress in the membrane's hydrophilicity, anti-fouling properties, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation achieves leaps and bounds in four pivotal aspects:
Self-Assembled Nanocomposite Films
By harnessing nano-scale precision control along with nano-doping modification, we've crafted ultra-thin, precisely ordered separation layers via polymer interface nanotechnology, thus overcoming the typical limitations in thickness uniformity and material diversity faced by conventional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
Our layer-by-layer self-assembly process has been optimized to precisely control the functional layer thickness, achieving a remarkable threefold reduction compared to traditional membranes. This optimization results in over 300% higher water flux and a 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond the limits of polyamide, we employ advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These cutting-edge materials exhibit outstanding oxidation resistance, withstanding chlorine exposure of up to 10 ppm, and offer remarkable pH tolerance, remaining stable across a broad pH range of 1 to 12.
Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, coupled with nanoparticle reinforcement, minimizes organic fouling by 50%. This effectively extends chemical cleaning cycles from 3 months to an impressive 6 months, leading to a 40% reduction in maintenance costs.
