E. coli in U. K. Mesophilic Anaerobically Digested Sludges
The results of a repeat survey carried out at five operational sites confirm that Mesophilic Anaerobic Digestion can reduce numbers of E. coli by up to 4 orders of magnitude. The average log reduction recorded in the second survey was 2.08, higher than observed in the first survey. 92% of reductions were 2 or greater, compared to 76% in the first survey. This was not unexpected, since the sites had been chosen as among the apparently better sites originally surveyed.
Average reductions at the sites varied between 1.35 and 3.36, but there were no clear reasons for the differences.
