Hospitality/Seawater and Brackish Water Desalination Applications
At Proshare, our extensive expertise in desalination technology is also applied to civil water desalination for hotels and tourist resorts. Ensuring a consistent fresh water supply is vital for these infrastructures, and our R.O. sea water and brackish water desalination solutions can meet the burgeoning demands of rapidly growing tourist areas.
Farming applications
Water is critical for ensuring the optimal health and performance of farm animals such as cattle, chickens, sheep, and pigs. Not only is the water quantity important, but its quality significantly influences the desired growth and productivity of these animals.
On farms, water can be sourced from various origins, such as water wells, civil water networks, and, to a lesser extent, rivers and other surface sources.
Except for water from civil networks that contains free chlorine, other sources often exhibit high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective method for mitigating these negative impacts, ensuring contaminated farm water undergoes essential treatment to reduce harmful substances for animals.

Proshare A Quantum Leap in Reverse Osmosis Membrane Technology
Proshare Our cutting-edge team has masterfully crafted a pioneering generation of reverse osmosis membranes, leveraging the revolutionary polymer interface nano-self-assembly technology. This innovation triumphs over the constraints of traditional methods through two groundbreaking advancements:
Revolutionary Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, our team has triumphantly minimized the thickness of the separation layer to an unprecedented level-at least three times thinner than the conventional polyamide thin film, which was previously bound by a 100 nm limit. This substantial innovation catapults water flux to new heights, remarkably boosting permeability.
Enhanced Performance Reimagined: By integrating nanoparticles paired with specialized hydrophilic polymers, we have ushered in transformative advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and resistance to oxidation.
When measured against traditional polyamide reverse osmosis membranes, Prosharehas achieved unprecedented breakthroughs in four pivotal aspects:
Innovative Self-Assembled Nanocomposite Films
Through the fusion of nano-scale precision control and nano-doping modification, we have crafted ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This innovative approach surmounts the challenges of conventional polyamide membranes in maintaining thickness uniformity and material versatility.
Unmatched Water Flux and Energy Efficiency
By honing the precise art of the layer-by-layer self-assembly process, we've adeptly controlled the functional layer thickness, achieving an extraordinary 3x reduction compared to traditional membranes. This accomplishment translates into >3x higher water flux coupled with a 30% reduction in energy consumption.
Novel Polymer Materials with Superior Durability
Breaking away from the confines of polyamide, our team utilizes avant-garde hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials showcase extraordinary oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH resilience (maintaining stability within a 1-12 pH range).
Advanced Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (with a contact angle of less than 10°) combined with nanoparticle fortification diminishes the tendency for organic fouling by 50%, prolonging chemical cleaning cycles from 3 months to an impressive 6 months, while slashing maintenance costs by 40%.
Our dedication to excellence is reflected in our comprehensive certifications, which include the prestigious Health & Safety Management System Certificate, the esteemed Environmental Management System Certificate, and the highly regarded ISO9001 Quality System Certificate.
Showcasing our commitment to innovation and technological advancement, we hold an Invention Patent for Membranes Production and an Invention Patent for our cutting-edge Multi-layer RO Membrane.
