Anionic and non-ionic surfactants in untreated sewage; distribution between solid and liquid phase

摘要

Due to high analytical costs it is not suitable to measure relevant compounds in all treatment facilities. The application of models would be an adequate instrument in order to assess emissions from WWTP. In order to obtain plausible results, reliable coefficients describing distribution between solid and liquid phase are essential in order to characterise WWTP influents. The calculated K_d values are regarded as suitable parameters for the estimation of adsorbed concentrations in WWTP influent when no measured values are available.
