Study design
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge, domestic, non-adapted
- Details on inoculum:
- treatment works, which treats predominantly domestic waste three days before the start of the test. On the day of collection, the sample was passed through a sieve with a mesh of ca. 1 mm2. A sub-sample (ca. 300 ml) was removed and centrifuged at ca. 3000 rpm for ca. 1 minute and the supernatant removed. The sample was then made up to volume with mineral salts medium (MSM, Appendix 1) and centrifuged. This procedure was carried out twice more and the sample was maintained aerated until required. Aliquots (10 ml) of a homogenised sample of the washed activated sludge were filtered through dried (approximately 105°C) and pre-weighed Whatman GF/C filter papers. The filters were dried for at least one hour, allowed to cool and re-weighed. The solids level in the sludge was determined and then an appropriate volume used to inoculate control and test vessels to give a final suspended solids concentration of 4 mg/l.
