In sewer systems where anaerobic conditions are present, sulfate-reducing bacteria reduce
sulfate to hydrogen sulfide (H 2 S), leading to sewer corrosion and odor emission. Various …

Instrumentation, control and automation (ICA) are currently applied throughout the urban
water system at water treatment plants, in water distribution networks, in sewer networks …

Ferric sludge, generated during drinking water purification process, can be considered as a
promising support with potential iron resource. Herein, magnetic bimetallic Co/Fe …

Iron sludge produced numerously from drinking water treatment plants can be recycled to
create catalyst for peroxymonosulfate (PMS) activation. In this study, iron sludge-derived …

Although the dose of biocides to sewers could control sulfide and methane production, the
high resistance of sulfate-reducing bacteria (SRB) to biocides would increase dosing …

Drinking water treatment sludge provides the iron resource and a promising support to
create bimetallic composites. In this work, a magnetic Co-Fe/SiO 2 layered catalyst (LC) was …

Fenton and Fenton-like sludge conditioning processes have been studied intensively due to
their superior efficiency in improving sludge dewaterability. But these processes inevitably …
