Freshwater supply is crucial for these infrastructures, and our R.O. technology for seawater or brackish water desalination offers an ideal solution to meet the expanding capacities and rising water demands of burgeoning touristic areas.
Farming Applications
Water is crucial for ensuring the health and vitality of farm animals, such as cattle, chickens, sheep, and pigs, and for optimizing their production performance. However, water quality, not just quantity, plays a significant role in influencing desired animal growth and productivity.
Farm water sources can include water wells, civil water networks, and, to a lesser extent, rivers and superficial sources. While water from civil networks often contains free chlorine, other sources tend to have high levels of dissolved and suspended solids and pathogens. Thus, reverse osmosis technology has proven to be exceptionally effective in mitigating these impurities, ensuring that farm water undergoes necessary technological treatments to reduce harmful substances for animals.
To secure optimal animal health and performance, it's critical that water from sources other than civil networks, which typically contain free chlorine, undergo technological treatment. Reverse osmosis technology effectively reduces high concentrations of dissolved and suspended solids and pathogens in water drawn from wells, rivers, and other sources, ensuring it is safe for farm use.

Proshare Groundbreaking Team Achievements in Revolutionary Reverse Osmosis Membrane Technology
Proshare Our pioneering team has masterfully crafted the next era of reverse osmosis membranes, leveraging cutting-edge polymer interface nano-self-assembly technology. We've eclipsed traditional limitations with two remarkable advancements:
Ultra-Thin Separation Layer Innovation: Leveraging advanced polymer interface nanotechnology, our team has triumphantly minimized the separation layer's thickness, achieving a remarkable reduction to less than a third of the conventional polyamide thin film's size (originally capped at 100 nm). This pivotal advancement dramatically boosts water flux, leading to a remarkable enhancement in permeability.
Superior Performance Enhancement: By integrating cutting-edge nanoparticles and uniquely hydrophilic polymers, we've pioneered transformative improvements in the membrane's hydrophilicity, anti-fouling performance, durability, and oxidation resistance.
When compared to traditional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation stands out with remarkable breakthroughs in four essential areas:
Self-Assembled Nanocomposite Films Mastery
With meticulous nano-scale precision control and nano-doping modification, we create ultra-thin, exquisitely ordered separation layers through advanced polymer interface nanotechnology. This technique surpasses the constraints of conventional polyamide membranes concerning thickness uniformity and material versatility.
Enhanced Water Flux and Energy Efficiency Excellence
Through the refined layer-by-layer self-assembly process, we achieve precise control of functional layer thickness, culminating in a threefold reduction compared to traditional membranes. This breakthrough delivers >3x amplified water flux and a 30% reduction in energy usage.
Innovative Polymer Materials with Unmatched Chemical Stability
Surpassing polyamide, we harness state-of-the-art hydrophilic polymers (such as refined polysulfones) and ceramic-organic hybrids. These innovative materials boast extraordinary oxidation resistance (thrive under 10 ppm chlorine exposure) and superior pH stability (resilient across a 1-12 pH range).
Advanced Anti-Fouling Surface Engineering
An ultra-hydrophilic surface (contact angle <10°) fortified with nanoparticle reinforcement cuts organic fouling tendency by 50%, doubling chemical cleaning intervals from 3 to 6 months and slashing maintenance expenses by 40%.
Our unwavering commitment to excellence is demonstrated through our prestigious certifications: Health & Safety Management System Certificate, Environmental Management System Certificate, and the highly esteemed ISO 9001 Quality System Certificate.
In our pursuit of innovation in water treatment technology, we proudly hold an Invention Patent for Membrane Production, as well as an Invention Patent for the Multi-layer Reverse Osmosis (RO) Membrane. The rigorous standards of product safety are met with our RoHS Compliance Certificate, ensuring environmentally friendly and health-conscious solutions.
