Full Description

The elimination of thermotolerant coliforms (Coli44) and spores of sulphite-reducing clostridia (SSRC) by full-scale water treatment was determined by large volume sampling. The objective was to determine the efficacy of full-scale treatment processes against microorganisms, both against relatively sensitive vegetative bacteria and resistant bacterial spores. In two short periods in winter and summer, much information was collected about the elimination of Coli44 and SSRC by the overall treatment, the contribution of the unit processes and the variability in elimination. Coli44 concentrations in the source waters were reduced by 3.2 to 6.3 log to an average concentration sufficiently low to achieve more than 99% compliance with the drinking water standard. The elimination of SSRC was lower (1.4 to 4.2) and SSRC were observed occasionally (
