Unbaffling baffle factors using tracer testing

Topic: Chlorine Disinfection Contact Time. Ie: looking into chlorine contact tanks and short-circuiting effects by determining the baffle factor through tracer testing.

What: Chlorine disinfection is vitally important as it is typically the final barrier to pathogens at a WTP. Validating disinfection practices at a WTP is therefore crucial in confirming disinfection effectiveness. The baffle factor is a commonly used method to simplify and estimate the short-circuiting behaviour within a contact tank. However recent tracer testing results undertaken to quantify baffle factors have shown potential pitfalls of adopting standard guidelines.
