Sewage sludge amended with zeolite and lime was stored for 42 days and investigated for plate counts of coliform faecal coliform bacteria and faecal streptococci. A decrease in plate counts of the observed microorganisms in experimental substrates was recorded compared to the control sludge, related to changes in pH. The devitalisation effect of lime persisted only for the period of increased pH. The following decrease in pH level resulted in revitalisation of the respective bacteria even to levels exceeding the original.
