Abstract

The inhibition effect of the disinfectants was investigated under laboratory conditions. COD removal, nitrification process and oxygen uptake rate were the observed processes. Disinfectants can be divided into a few groups depending on the present biocides. The results of the experiments showed a significant influence of the disinfectants containing sodium hypochlorite on the activated sludge. Domestos and Savo caused the highest inhibition on the respiration, 99% and 100%, respectively; while Asanox and Clorox had the highest effect on COD removal, 97% and 100%, respectively. Bref duo active, which also contains sodium hypochlorite, caused the lowest inhibition for all observed processes. Disinfectants based on other biocides did not cause significant inhibitions.
