Overview and Effects
The cleaning effect of ultrafine bubbles (UFBs) makes soils easier to wash away and can help reduce soiling in drainpipes.
Test
Comparison of drainpipe soil removal after 10 seconds of washing


| Test overview | An artificial soil (oil, protein, water, etc.) was applied to a U-shaped pipe and left to dry for one day. Water was stored in a tank and drained by gravity, passing through the pipe at 11 L/min for 10 seconds, and the results were compared. |
