The pollutants introduced into the sewerage collecting system and reaching municipal wastewater treatment plants WWTPs derive principally from human activities Wastewater Quality Monitoring and Treatment Edited by P. Quevauviller O. Thomas and A. van der Beken 2006 John Wiley Sons Ltd. ISBN 0-471-49929-3 180 Treatability Evaluation and in particular from domestic sources industrial districts and urban run-off rainwater. A very large amount of different organic and inorganic compounds estimated as several thousand has been detected in raw wastewater. The treatability of these compounds in the conventional WWTPs can differ significantly depending on each considered contaminant. The importance of knowing the treatability of the different kinds of pollutants present in municipal wastewater is related to the prediction of the fate of these contaminants in WWTPs before the discharge in the receiving water bodies. The following principal categories of contaminants in municipal raw wastewater can be distinguished Organic compounds as aggregate parameters. The whole amount of organic matter is generally measured as aggregate organic parameters such as chemical oxygen demand COD total organic carbon TOC
