CT Disinfection Made Simple
Brock Rush, M. Eng., P. Eng., Alberta Environment
The following discussion is about CT Disinfection. It was prepared as a presentation for the Alberta Water and Wastewater Operator's Association annual conference in Banff, Alberta on March 13, 2002. It is intended to outline an easy to follow procedure that will allow operators of surface water and groundwater under the direct influence of surface water treatment plants to ensure that they are providing good disinfection to the water they treat, that they are producing the safest water possible and to demonstrate that they have done so.
The following discussion will briefly cover the 'What Is', the 'Who Uses', and the 'Why you need' CT Disinfection.However, the main focus of the discussion will be on how to use CT Disinfection to demonstrate that you are producing good quality water from your water treatment plants. We will review how CT Disinfection works and then work through an example. The main goal is to demonstrate that CT Disinfection is pretty simple to use.
