Flocculation of dirty water
Videonummer 11936814
| Timelapse footage of the flocculation of dirty water with aluminium ions. Aluminium sulfate is added to the water, and the positively-charged aluminium ions attract negatively-charged clay and other particles, causing them to clump together. This solid floc thickens and eventually settles to the bottom, allowing the clean water to be used. | |
