STORAGE TANK MANAGEMENT TO IMPROVE DRINKING WATER QUALITY : CASE STUDY

BARBEAU B. / BESNER M. C. / GAUTHIER V. / et al. - ARTICLE DE PERIODIQUE - 2000

Water storage management. In order to improve drinking water quality in a large North American city, chlorine decay, residence time and flow were measured in a tank. The experimental results and model utilization show that the decay is due not only to biofilm presence or corrosion particles but also to a too long residence time. Different solutions (new design and operational conditions) are proposed to get detectable chlorine residuals.
