Abstract: Effective aerobic treatment of piggery slurry was
achieved in a continuous farm scale process sited at a small
piggery (2000 pigs). The  plant design and the operating
conditions were based on data obtained from pilot-scale studies
with the aim of preventing or reducing odours  from pig slurry at
a minimum cost. Raw slurry was separated before passing into the
main treatment vessel. Aeration was achieved by  recirculating of
slurry (achieving jet mixing of the tank contents) through a
venturi where air was entrained. Aeration was controlled to
maintain  redox potential between 100 and 200 mV E(h). Slurry was
added and withdrawn at hourly intervals, to provide nominal
residence times of 1, 2  and 4 days. The performance of the
aerobic treatment process in terms of COD reduction could be
predicted using data from laboratory and  pilot-scale
experiments. Some allowance could be made for minor feed
fluctuations but a more comprehensive model will be necessary for 
predictions where larger variations occur in operating
conditions. Assessments were made of odour quality using dynamic
dilution  olfactometers for odour strength, and volatile fatty
acids (VFA) concentration as an indicator of odour offensiveness.
Results indicate that pilot- scale experiments may overestimate
by 10-20% what can be achieved with the farm-scale plant.
Nitrogen losses were greatest in the 4-day  residence time trial
with 56% lost in the form of N2 gas following a
nitrification/denitrification process. Conversely, in the short
residence time  trials, virtually all of the nitrogen was
conserved.
