This paper reviews microbiological and biochemical aspects of the enhanced biological
phosphate removal (EBPR) process. The discussion includes: microorganisms responsible for …

The review presented in this paper focuses on applications of particulate biofilm reactors (eg
Upflow Sludge Blanket, Biofilm Fluidized Bed, Expanded Granular Sludge Blanket, Biofilm …

This paper reviews the long-standing bulking sludge problem in activated sludge systems.
Despite the extensive amount of research that has been done on bulking sludge, it still occurs …

In a sequencing batch reactor (SBR) granules of aerobic heterotrophic microorganisms
were cultured. The effect of different operational conditions on the formation of these aerobic …

Aerobic granular sludge was cultivated in an intensely mixed sequencing batch airlift reactor
(SBAR). A COD loading of 2.5kg Acetate-COD/(m 3 d) was applied. Granules developed in …

Currently available microbiological techniques are not designed to deal with very slowly
growing microorganisms. The enrichment and study of such organisms demands a novel …

+ per litre has been developed at the Delft University of Technology. The SHARON process
operates at a high temperature (30–40 C) and pH (7–8). The process is performed without …

In the anaerobic phase of a biological phosphorus removal process, acetate is taken up and
converted to PHB utilizing both energy generated in the degradation of polyphosphate to …

In a laboratory scale sequencing batch reactor (SBR) granules were cultured under aerobic
conditions. To enhance the growth of granular sludge the SBR was operated with very short …

Denitrifying dephosphatation enables the removal of phosphorus and nitrogen with minimal
use of COD, minimal oxygen consumption and minimal surplus sludge production. …
