Abstract

The effects of reaction temperature (25 to 50°C) and mean microorganism residence time (0·18 to 8 days) in the aeration vessel of a continuous-culture system for the treatment of piggery slurry are outlined. A model developed to describe the effect of mean residence time on the characteristics of piggery slurry is used to produced a series of correlating equations for residual COD, TS, TSS and BOD5. These equations are compared with equations developed earlier for treatment at 15°C.
