Full Description

Based on paper evaluation using water treatment plant simulation models and the City'shydraulic model, conversion of the existing filters to filter adsorbers were found to be the mostappropriate process improvements to comply with upcoming Stage 2 D/DBP Rule. The media inthese filter adsorbers are expected to be replaced at certain intervals to achieve adequateprecursor removal by adsorption and biodegradation. The City will also consider the inclusionof ozonation in its treatment process to minimize granular activated carbon (GAC) replacement frequency. Subsequentphases of the study focused on further refinement of the filter adsorber design criteria throughpilot-scale studies. Results of the pilot scale studies were utilized to determine an itemized costestimate for the process improvements. The City is currently in the process of demonstrating theperformance of filter adsorber on a full-scale basis. A comprehensive approach to water processplanning for compliance with upcoming D/DBP regulations is presented. Includes tables, figures.
