The suitability of concentrated abattoir stabilization pond sludge for the start-up of UASB reactors was studied in a continuous laboratory set-up. A mixture of volatile fatty acids (acetic, butyric and propionic) was used as substrate to establish the optimum parameters for the start-up.

The concentrated sludge had the capacity to handle a high loading condition (15 kg COD/m3 of reactorday) within 5 weeks of operation. The range of% COD reduction was 78%-94%. Different sludge concentrations gave similar VFA and COD reductions. This can be attributed to the severe washout of the sludge at the initial phase of operation and the eventual retention of similar sludge concentrations of approximately 20 kg VSS/m3 of reactor.
