Journal Article
MENSAH, L., PETRIE, B., SCRIMSHAW, M., CARTMELL, E., FLETTON, M. and CAMPO, P. 2023. Influence of solids and hydraulic retention times on microbial diversity and removal of estrogens and nonylphenols in a pilot-scale activated sludge plant. Heliyon [online], 9(9), article e19461. Available from: https://doi.org/10.1016/j.heliyon.2023.e19461

The removal of EDCs in activated sludge processes can be enhanced by increasing solid and hydraulic retention times (SRT and HRT); it has been suggested that the improvement in removal is due to changes in microbial community structure (MCS). Though... Read More about Influence of solids and hydraulic retention times on microbial diversity and removal of estrogens and nonylphenols in a pilot-scale activated sludge plant..
