DBP Precursor Removal Special Study in Irvine, KY

On April 29, the Optimization Team conducted a special study to evaluate bench-scale removal of DBP precursors at the drinking water treatment plant in Irvine, KY. During this study, jar test simulations of the drinking water clarification processes were conducted, comparing TOC removal under the plant’s operational conditions and under alternative plant settings. The outcome of this – and potentially future – studies will shape future DBP optimization training approaches. The system that hosted the team is a “graduate” of a 2011 DBP Performance Based Training project. The plant has maintained optimization as a “way of doing business” to produce excellent water quality in the plant and minimize water quality degredation in their distribution system.
