Most full scale BAC Plant Operators use Research Laboratory Services for their BAC Aging Profiles, including Seqwater, MidCoast Water, Rous Water, Fraser Coast, Veolia Water, ATJV (Acciona), Orange City Council, and Auckland Watercare.
To predict the bed life of Biological Activated Carbon (BAC) filters, samples of the carbon are taken annually and monitored for fouling. By plotting this data over time, the life expectancy of the carbon under the specific operating conditions can be assessed. This is particularly useful for asset managers to budget for carbon replacement, or for operators that are experiencing problems with their existing BAC filters.
