#101 - Quantum Wei: Harmony desalting

Quantum Wei, founder of Harmony Desalting, explained their Batch Reverse Osmosis (RO) technology, which dynamically adjusts pressure to save energy. Using conventional membranes and a unique bladder system, Batch RO handles fluctuating salinity and pressure, making it more efficient and resilient against fouling and scaling. At the Yuma Desalting Plant, Batch RO treated scaling-prone brine from a brackish water RO system, achieving 83% water recovery without additional antiscalants. Harmony Desalting is scaling up Batch RO for industrial use, integrating multiple membrane modules, and testing under higher salinity to make desalination more affordable and accessible. Independent control of process parameters gives Batch RO an edge, offering more water with less energy and fewer chemicals.
