Abstract

Biogas may be produced from communal sewage sludges by anaerobic decomposition. To follow up the decomposition processes enzyme activity tests have been applied. It is advantageous to use these activity tests if there are frequent substrate-, or specific organic matter load changes in the digesting towers. For describing the total activity of the cells, dehydrogenase-, while for following up the frequent substrate changes protease-, lipase- and cellulase enzyme activity analyses have been carried out. No internationally accepted standards are available for testing the enzyme activity of sewage sludges. Thus, in our experimental work we modified the enzyme activity analyses described earlier in the special literature for the tests of other than sewage sludge samples. Our enzyme activity tests can be completed quickly and at a relative low cost, thus it is possible to use them in generally equipped wastewater treatment laboratories also.
