Claims21
A method for treating an aqueous system with chlorine dioxide while exposed to sunlight, the method comprising:
- adding to the aqueous system an effective amount of UV absorbent and chlorine dioxide;
- inhibiting UV degradation of chlorine dioxide by absorbing UV with the UV absorbent;
- sustaining a chlorine dioxide concentration to obtain a Ct value, and
- wherein the Ct value is sufficient to achieve remediation.
