Sažetak
Nematodes are among the organisms most commonly found in treated water. Although they are believed to be harmless, colonization of nematodes by pathogenic bacteria may transform them into harmful contaminants of the drinking water. Thus, efficient disinfectants must be applied to inactivate and remove nematodes. In the present study, nematode inactivation using different concentrations of ozone, chlorine dioxide, and chlorine for different exposure times are described. Three different disinfection models were tested. Based on experimental data, the best statistically significant relationship between mortality of nematodes in probits (Y), concentrations of disinfectants mg/L (C), and the exposure times in minutes (t) was established as Y = a*log(C) + b*log(t) + c. The estimated values of regression coefficients a, b, and c were 6.89, 0.76, and 1.13 for ozone, 0.66, 1.23, and 5.28 for chlorine dioxide and 1.59, 0.92, and 3.06 for chlorine, respectively. Comparison of the predicted LC(90) molar concentrations of the investigated disinfectants, chlorine dioxide, ClO2, was found to be the most effective disinfectant, followed by ozone, O-3, while chlorine, Cl-2, was the least efficient disinfectant for inactivation of nematodes.
