FINAL REPORT ON THE ASSOCIATION BETWEEN AOC AND BDOC AND AN EVALUATION OF THE LUMAC/KIWA BIOFILM MONITOR
Report No FR0463
The customer will benefit from a better understanding of the relationship between assimilable organic carbon (AOC) and biodegradable organic carbon (BDOC) in potable waters and from the influence of biodegradable organic matter (BOM) on the potential for biofilm formation in distribution systems.
To determine the relationship between AOC and BDOC in potable water. To evaluate the KIWA/Lumac biofilm monitor.
The water industry requires a better understanding of the impact of novel water treatment processes on biodegradable organic matter (BOM), and on the implications of BOM on water quality in distribution. Reliable methods of measurement are therefore required. A review of the literature has been produced, but information on the relationship between AOC and BDOC and their influence on biofilm formation is required.
The following recommendations are made for further work:
VI RESUME OF CONTENTS
This report has been produced in connection with the Foundation for Water Research contract on Water Quality in Distribution (F-1702). Presented in Section 2 of this report are details of the operation of the Spanish BDOC methodology and the results of a comparison of the data obtained from this method and those obtained from the WRc AOC and Joret BDOC methods. In Section 3 details are given of an evaluation of the KIWA/Lumac biofilm monitor when applied to the determination of the biofilm formation potential of a high quality groundwater with and without an AOC supplement.
