Table 1 provides an overview of the bacterial population found in backwash water samples from the first stage filter (‘BW 1st RSF’) and the pilot filter column (‘BW A1’). The sequencing results of sample ‘BW 1st RSF’ are based on 188,241 sequences, whereas the results of sample ‘BW A1’ are based on 55,298 sequences. The taxonomic trees are shown in Appendices A and B (Supplementary Information, available with the online version of this paper).
