Abstract

The objective of this study was to evaluate the effects of CEPT for leachate and sewage co-treatment in a POTW. The results showed that ferric and aluminum coagulants remove about 54 - 74% organic matter where ferric performed better than aluminum coagulant. However, ferric coagulant was found to exacerbate the UV absorbance after coagulation at high dose due to the interaction with dissolved organic matter by forming soluble transition metal complexes. These organo-metal complexes have been found to increase the UV absorbance and this study provides the scientific background for such phenomenon.
