Effects of phosphorus on biofilm disinfections in model drinking water distribution systems

Effects of phosphorus on biofilm disinfections in model drinking water distribution systems.

Drinking water biofilm development is affected by the available nutrient levels and the presence of disinfectants. Phosphorus is recognized as another important limiting nutrient besides organic carbon. In this study, drinking water biofilms were developed in annular reactors to examine the effects of phosphorus on the biofilm disinfections with free chlorine and monochloramine. Phosphorus addi...

Dynamics of Biofilm Regrowth in Drinking Water Distribution Systems

UNLABELLED The majority of biomass within water distribution systems is in the form of attached biofilm. This is known to be central to drinking water quality degradation following treatment, yet little understanding of the dynamics of these highly heterogeneous communities exists. This paper presents original information on such dynamics, with findings demonstrating patterns of material accumu...

Study on Microbiological Quality of Rural and Urban Drinking Water in Distribution Systems of Ijroud, Zanjan in 2013-2015

Background: Providing safe drinking water has critical importance to human societies. The aim of this study was to investigate microbiological quality of drinking water in distribution system of urban and rural regions of Ijroud, in Zanjan province.   Materials and Methods: In present descriptive study, the microbiological examination of drinking water was conducted in 15 facilities with...

Pre-processing and visualization of biofilm development in drinking water distribution systems

Biofilm develops in drinking water distribution systems (DWDSs) as complex microorganism communities covered by an extracellular polysaccharide which provides them structure, protection against disinfectants and helps retain food. Biofilm poses a serious risk to DWDSs. The presence of substantial and active attached biomass in the inner wall of pipes can protect pathogenic microorganism, lead t...
