TL;DR: It is shown that total cell concentration measured with FCM is a rapid, easy, sensitive and importantly, a descriptive parameter of several widely applied drinking water treatment processes.

TL;DR: A novel bioassay for assessment of assimilable organic carbon with the detection of selected organic acids, aldehydes and ketones to study organic by-product formation during ozonation concluded that direct ozone reactions were mainly responsible for the formation of small organic compounds.

TL;DR: This study shows that the combination of different analytical methods allows detailed quantification of the microbiological activity in drinking water biofilters.

TL;DR: This study documents the direct influence of the filter biomass on the microbial community composition of the final drinking water, particularly when the water is distributed without post-disinfection.

TL;DR: This study used a multi-parametric approach that encompasses different aspects of microbial water quality including microbial growth potential, microbial abundance, and microbial community composition to monitor biological stability in drinking water of the non-chlorinated distribution system of Zürich.
