For example, copper sulfate will kill algae, but will add copper to the pond bottom, which some day you may have to clean up. Ozone will oxidize most HIP's and heavy metals. Therefore, the Benthal or pond muck containing HIP and metals will, over time, oxidize. The pond at my golf course has caution signs all around it warning of contamination. Yes, by bubbling ozone through the use of our Turbohydrozone Systems, the nitrates, herbicides, insecticides and pesticides will be oxidized and reduced.
Chlorine is also an oxidizer used in purifying drinking water.
However, it does leave chemical taste and smell residues, whereas ozone reverts back to ordinary oxygen, leaving no residue. Ozone is many times more powerful than chlorine. It will circulate in the best method, from bottom to top. Copyright 2000 RGF Environmental. All rights reserved.
