Project Details

Description

The project concerns changes in water quality due to microbial growth during the transport of drinking water from waterworks to the consumer.
The major part of the biomass in drinking water system is attached to the inner surfaces of the waterpipes as a 'biofilm'. The project focuses on the factors controling the growth of this biofilm, primarily the concentration of microbial available nutrients and the flow velocity in the pipes. The kinetics of the growth will be investigated, with respect to determining the effect of the hydraulic retention time in the water distribution system. These factors will be investigated in a constructed model pipe system.
The goal of the project is to provide an useful tool for assessing the microbial growth potential of various types of water in different drinking water distribution systems.
