Abstract
Piggery slurries treated in pilot-scale aeration vessels were sieved or centrifuged to remove a proportion of the solids. The resulting liquid fractions were stored at 10°C; at intervals samples were removed and analysed for volatile fatty acid (VFA) content. Removal of solids using fine sieves or the decanting centrifuge extended the storage times by one-third before the VFA level indicated that offensive odours had returned to the slurries. A laboratory centrifuge tripled the stable-storage period.

Alkalinity measurements are used in the interpretation and control of water and wastewater treatment processes and can be interpreted in terms of specific substances only when the chemical composition of the sample is known.

The effects of initial total solids (TSi) and the degree of aerobic treatment on the subsequent stability of piggery slurry during anaerobic storage were investigated and methods of increasing stability are discussed.
