- Description
- Our recent pilot-scale investigations have shown that Ozone/BAC can provide significant removal of THM precursors and hence reductions in THM formation potential. However, the removal efficiency was found to be highly dependent on the empty bed contact time of the filter, with longer times yielding significantly better removal. The characteristics of the organic matter in the water may also influence the removal efficiency. While Ozone/BAC treatment may be capable of meeting the current ADWG limit in THMs even for a water that is highly laden with natural organic matter, it may struggle if tighter THM limits are introduced. Our work highlights the importance of undertaking pre-design testing to ascertain the effectiveness of Ozone/BAC in reducing THM precursors for a specific water.
