The batch experiments were investigated to optimize chlorine disinfection for Copepod of zooplankton using response surface methodology. The independent variables were chlorine dosage, exposure time and organic matter concentrations. The experimental results showed that the body surface structure provided Copepod with strong protection against disinfection. The variables of dosage, exposure time and organic matter concentrations significantly influenced the inactivation rate of Copepod. The disinfection rate was remarkably increased with the increasing chlorine dosage and exposure time. Organic matter concentrations had an obvious negative influence on Copepod inactivation. The polynomial optimal model for Copepod removal was established for the chlorine disinfection in waterworks. The analysis of variance showed that the F-value of 73.73 implied the model significance and the P-value less than 0.0001 indicated its good fit to use in the matrix. The model coefficient with R² value was 0.9852. The evaluation proved that the model had a suitable predication for the application in waterworks.
