Benefits of UV254 Monitoring ‣ Improved chemical feed control ‣ Consistent effluent turbidity ‣ Reduced chemical costs ‣ Important factor in identifying the “optimal” coagulant ‣ Improved DBP control ‣ Helps optimize UV disinfection
Summary Ensure that chemical feed rates are satisfactory under all plant conditions Does the plant use the right coagulant Verify that rapid mixing operation is adequate Adjust, if possible, flocculation speed at least seasonally Implement raw water UV254 monitoring (surface WTPs)
