Sludge biochar can be used as bio-carrier to enhance aerobic granular sludge, however, its impact on the formation and especially long-term stability of granules has not been fully investigated. In this paper, sludge was cultivated in two parallel sequencing batch reactors (SBRs), R1 R2, with without addition activated inoculum, respectively. The characteristics, wastewater treatment performanc...

The effect of salinity on aerobic granular sludge treating fish-canning wastewater was evaluated through a biofilm model. addition inhibition term to the model could accurately describe reactor performance with different salinities.

This paper investigates denitrification of brines originating from membrane treatment of groundwater in an upflow sludge blanket (USB) reactor, a biofilm reactor without carrier. A simulated brine wastewater was prepared from tap water and contained a nitrate concentration of 125 mg/l as N and a total salt concentration of about 1%. In order to select for a suitable energy source for denitrific...

Phenolic compounds cause problems for conventional treatments due to their toxic and inhibitory properties. This work investigated the treatability of phenolic compounds by using two membrane-bioreactor systems, namely: activated sludge coupled with MBR (AS-MBR) and biological granular activated carbon coupled with MBR (BAC-MBR). Initially, the system was fed with phenol (500 mg/L) followed by ...

Aerobic granular sludge/Nereda technology has proven to be more beneficial compared to activated sludge systems. Until now not much research has been spend on treatment of Nereda excess sludge (NES). In this study the biodegradability of NES is investigated, combined with thermal pressure hydrolysis (TPH) as pre-treatment method and the application of an up-flow digester concept. The maximal bi...
