Fig. 2: Time series water quality parameters.

Time series of total/intact cell counts and total/intracellular ATP in the bulk water (panels A and B) and in the biofilm (panels C and D) as well as total chlorine and temperature (panels E and F) during the two phases of reactor operation in the five replicate reactors. Phases are designated by background colors (purple: Oct. 2019 to mid-March 2020; pink: mid-March 2020 to October 2020).
