Disinfectants break down faster, microbes grow like crazy, and you get more nasty disinfection byproducts (DBPs). Plus, tank materials can actually leach into your water. To keep things clean, you need to move water through quickly, keep disinfectant levels up, stir things around, and pick tank materials that won&#8217;t mess with your water.<\/div>\n<div class=\"block-record-info\">\n<p class=\"FR_field\"><span class=\"FR_labelBy:<\/span>Damian, L (Damian, Laura)<sup><b>[\u00a01\u00a0]\u00a0<\/b><\/sup>; Patachia, S (Patachia, Silvia)<sup><b>[\u00a0<1\u00a0]\u00a0<\/b><\/sup>; Scarneciu, I (Scarneciu, Ioan)<sup><b>[\u00a0<2\u00a0]<\/b><\/sup><\/p>\n<\/div>\n<div class=\"block-record-info block-record-info-source\">\n<p class=\"sourceTitleENVIRONMENTAL ENGINEERING AND MANAGEMENT JOURNAL<\/p>\n<div class=\"block-record-info-source-values\">\n<p class=\"FR_field\"><span class=\"FR_labelVolume:<\/span>\u00a018<\/p>\n<p class=\"FR_field\"><span class=\"FR_labelIssue:<\/span>\u00a05<\/p>\n<p class=\"FR_field\"><span class=\"FR_labelPages:<\/span>\u00a01089-1095<\/p>\n<\/div>\n<p class=\"FR_field\"><span class=\"FR_labelPublished:<\/span>\u00a0MAY 2019<\/p>\n<p class=\"FR_field\"><span class=\"FR_labelDocument Type:<\/span>Article<\/p>\n<\/div>\n<div class=\"block-record-info\">\n<div class=\"Abstract<\/div>\n<p class=\"FR_fieldThis study looked at how the material of storage tanks and different stirring methods affect drinking water quality. We tracked changes in water quality for two weeks, both when it was still and when it was stirred with magnets or sound waves. We checked things daily, like how many germs were growing (total count, lactose-positive, coliform, E. coli), and physical stuff like cloudiness and chlorine levels. It turns out, water quality changed differently depending on how long it sat and how it was treated. Glass tanks didn't encourage germ growth at all, but polyethylene tanks were a big problem for bacteria. Both mechanical stirring and sonication, which uses sound waves, really helped cut down on biofilm forming on tank walls, no matter what the tank was made from. However, sonication didn't work well for water in polyethylene tanks. Why? It actually made the water warmer, which just made the free-floating bacteria more active.<\/p>\n<p><a
