Determination, Interpretation and Modeling of Chlorination by-Products Concentrations in Surface Waters


Nikolaou A., Arhonditsis G., Kolovoyiannis V., Golfinopoulos S. and Lekkas T.


The formation of chlorination by-products (CBPs) was investigated by bench-scale chlorination experiments with surface waters from different sources in Lesvos island, Greece. The main factors studied were organic matter content of water (expressed as UV-272 absorbance), time and chlorine dose. The...
