Thesis (MEng (Civil Engineering))--University of Stellenbosch, 1983. / 129 leaves printed on single pages, preliminary pages and numbered pages 1-1 – 12.5. Includes bibliography, list of abbreviations and list of figures. / Digitized at 300 dpi black and white PDF format (OCR), using KODAK i 1220 PLUS scanner. / ENGLISH ABSTRACT: The remedy of a bulking sludge was investigated by the principle
of selection of microorganisms. Selection of microorganisms in activated
sludge was achieved by putting a selection compartment, with a high
substrate concentration, ahead of the main aeration basin. The initial
results in the experiments indicated selection of microorganisms and
a reduction of SVI, but complete selection of microorganisms could not
be obtained. / AFRIKAANSE OPSOMMING: Die herstel van 'n uitdyende slyk is deur die beginsel van selektering van
mikroorganismes ondersoek. Selektering van mikroorganismes in geaktiveerde
slyk is toegepas deur n seleksie kompartement met 'n hoë substraatkonsentrasie,
voor die groot belugtingsbak te plaas. Die aanvanklike resultate wat
verkry is, het selektering van mikroorganismes en 'n verlaging in die SVI
getoon, maar volledige selektering van mikroorganismes kon nie verkry
word nie.
