Full Description

University of Central Florida (UCF) is currently conducting a large-scale pilot study todetermine the effect of blending different source waters on distribution systems water quality asa part of AWWARF and Tampa Bay Water tailored collaboration project (TBW project). In thisstudy, finished waters from seven different processes are blended in varying ratios beforedistribution to eighteen pilot distribution systems (PDS) and various chemical and biologicalwater quality parameters are monitored for a total of 12 months. This paper addresses surfacecharacterization of aged unlined cast iron pipe, development of equilibrium model, comparisonof model prediction and pilot observations. Includes 10 references, tables, figures.
