Abstract

The dielectric measurement is a rapid and non-destructive method to investigate the physichochemical change in the examined materials. Many researches observed the dielectric properties of pure water, different materials from the food industry, but there is less information about the dielectric charachteristic of wastewater and sludge. Our study aims to detect correlation between dielectic constant and SCOD/TCOD parameter, to verify if different microwave irradition treatments can enchance the solubilization of organic matter in municipal sludge. With the detemination of soluble chemical oxygen demand (SCOD) we detect the effects of different microwave irradition treatments on the sludge‘s organic matter solubility. Our results show dielectric measurement is a suitable method to detect the changes in the soluble organic matter content, since there is a strong linear correlation between the dielectric constant (ε‘) and the SCOD/TCOD parameter, which indicates the the solubility of the organic matter.
