Title: An overview on the reactors to study drinking water biofilms
Issue Date: 2014
Abstract: The development of biofilms in drinking water distribution systems (DWDS) can cause pipedegradation, changes in the water organoleptic properties but the main problem is relatedto the public health. Biofilms are the main responsible for the microbial presence indrinking water (DW) and can be reservoirs for pathogens. Therefore, the understanding ofthe mechanisms underlying biofilm formation and behavior is of utmost importance inorder to create effective control strategies. As the study of biofilms in real DWDS is difficult,several devices have been developed. These devices allow biofilm formation undercontrolled conditions of physical (flow velocity, shear stress, temperature, type of pipematerial, etc), chemical (type and amount of nutrients, type of disinfectant and residuals,organic and inorganic particles, ions, etc) and biological (composition of microbial community e type of microorganism and characteristics) parameters, ensuring that theoperational conditions are similar as possible to the DWDS conditions in order to achieveresults that can be applied to the real scenarios. The devices used in DW biofilm studies canbe divided essentially in two groups, those usually applied in situ and the bench top laboratorial reactors. The selection of a device should be obviously in accordance with the aimof the study and its advantages and limitations should be evaluated to obtain reproducibleresults that can be transposed into the reality of the DWDS. The aim of this review is toprovide an overview on the main reactors used in DW biofilm studies, describing theircharacteristics and applications, taking into account their main advantages andlimitations.
