Activity measurements of enzymes have been used in the research. Prope
rties of microorganism populations of activated sludge have been estim
ated by this method. During the experiments, the activity of the follo
wing enzymes catabolising polyphosphate changes were measured: polypho
sphatases, adenylate kinase, AMP:PP phosphotransferase. In order to de
signate the phosphorous release and uptake rare, a batch test has been
carried out together with the activity measurement. Activated sludge
for the experiments was taken from three substantially different waste
water treatment plants (WWTP). The enzymatic activities of the activat
ed sludges which come from different WWTP indicate a high ability of m
icroorganisms to change polyphosphates. The interpretation of the resu
lts shows good correlations of polyphosphatase and AMP:PP phosphotrans
ferase activity with the phosphate release rate. The results of the ex
periments indicate the suitability of the activity measurement for def
ining potential possibility of a microorganism population to carry out
biological phosphate removal by the activated sludge method. (C) 1997
