Ozone does a great job removing color from water. Ozone is an oxidant and will bleach water efficiently. We were recently shipped a sample of wastewater from a client looking to have us determine if ozone would remove color from their water. We were very impressed with the results, and decided to share, see video below for impressive results of ozone removing color in this water sample:
The water sample shown is 250 ml. Ozone is generated from oxygen. Oxygen/ozone flow rate of 1 LPM is initiated about 5 seconds into the video. Ozone concentration is 10% by weight.
