Research on Dewatering Ability of Municipal Sludge under the Treatment of Coupled Acid and Microwave
Geofluids, Volume 2021, Issue 1, 2021., 2021 Municipal sludge is a by‐product of urban sewage treatment; it has high water content and contains many hydrophilic extracellular polymeric substances (EPS). It is difficult to achieve deep dewatering of sludge. Therefore, it is necessary to find an efficient method to treat sludge.

A review on the dewaterability of bio-sludge and ultrasound pretreatment
Ultrasonics Sonochemistry, 2004 Bio-sludge, which contains large quantities of water, biomass and extracellular polymeric substances (EPS), is difficult to be dewatered as a "super-compactable" sludge [Water Res. 35 (5) (2001) 1358]. Reported water content in bio-sludge was commonly about 80-90% wt after dewatering process.
