Absorbance based water quality indicators as parameters for treatment process control with respect to organic substance removal

The dependence between individual water quality indicators and the UV254 was presented in the paper. Derived dependences allow to calculate values for these indicators using only the absorbance measurement, which could be easily on-line monitored. This approach make possible to reduce number of performed laboratory analyzes, used for the efficient controlling of water purification process. Identified relations are not universally applicable even for individual specific water source. These could be described with sufficient precise only for water samples from particular treatment step. Presented methodology can be helpful for exploitation of real water treatment systems to quick and efficient evaluation of individual purifying processes.
