Role of Smart Tanks in Distribution Water Quality Management Webinar IEPA#12669

IEPA#: 12669

SummaryWith the promulgation of the EPA’s Stage 1 and Stage 2 Disinfection Byproduct Rules, water treatment operators and utilities scrambled to ensure their plants were in compliance with THM limits and more carefully monitored chlorine dosing – or switched to the more persistent (long-lived) chloramine as a secondary disinfectant – which had a much lower propensity to form THM’s.

However, a new problem then became more apparent - residual chlorine (and other disinfectants) may also react further within the distribution network forming DBP’s —both by further reactions with dissolved naturally occurring organic matter and with biofilms present in pipes and tanks. In addition to being highly influenced by the types of organic matter in source water, species and concentrations of DBPs vary according to the type of disinfectant used, the dose of disinfectant, the concentration of natural organic matter and bromide/iodide, the time since dosing (i.e. water age) and temperature.

The emergence of “smart tank” design and operations now provides utilities with the ability to utilize water storage tanks as water quality intervention points. Tanks provide the perfect intervention point to solve THM spikes and low disinfectant residuals, but it all starts with powerful mixing. By revisiting water storage resources as intervention points, overall treatment can be optimized with the added potential for reducing treatment plant costs as they relate to THM reduction and disinfectant residual levels.

This presentation will examine the under-utilized water storage tank as an asset that can be used to improve distribution water quality with several methodologies. Several cases studies that illustrate “smart tank” technology improving chlorine residuals, reducing THM’s and maintaining chloramine residuals will be included in the presentation.
