These portable systems replicate the multi-barrier purification process of large, central systems but in a miniaturized, integrated package. The process typically involves several stages:
Pre-filtration: Removes sediments and chlorine.
Reverse Osmosis (RO): The core of the system. It forces water through a semi-permeable membrane, removing over 90-99% of contaminants, including ions, bacteria, and endotoxins.
Deionization (DI): Polishes the water, removing any remaining ions.
Ultrafiltration: A final barrier to remove any bacteria or endotoxins.
Advanced models include continuous water quality monitoring with sensors and alarms that will halt treatment if purity standards drop, ensuring patient safety is never compromised.
