Fate of NaClO and membrane foulants during in-situ cleaning of membrane bioreactors: Combined effect on thermodynamic properties of sludge
H Zhang, M Sun, L Song, J Guo, L Zhang - Biochemical engineering …, 2019 - Elsevier
In this study, the fate of sodium hypochlorite (NaClO) and detached membrane foulants and
their impacts on the thermodynamic properties of raw sludge were investigated in a
membrane bioreactor (MBR). It was found that about 20.3% of the total NaClO was
potentially released into the bulk sludge, which significantly altered the raw sludge surface
properties, such as a reduction in the number of surface electron donor components (γ−)
and an increase in surface hydrophobicity. After exposure to NaClO, the treated sludge had …
