Abstract

Samples of waste water were taken from three different sites of a river; which is located in an agricultural region '' Zemamra''; city El Jadida; Morocco. These wastes water are rejected without any previous treatment and they are used in the irrigation of fields near the river. As a first step; these samples were analysed by the conventional methods for a physicochemical and bacteriological evaluation. This analysis showed the presence of organic and inorganic pollutants in these samples. Furthermore; the electrical and dielectric properties of these samples were investigated in the frequency range 100 mHz to 100 KHz at room temperature. These properties were analysed by using the all electrical and dielectric functions. The results indicate that all samples have similar dielectric behaviour. Two processes of conduction and relaxation have been observed, due to the various organic or inorganic loads in each samples. The analysis of the electrical and dielectric properties of these samples might be used to examine the electrokinetic behaviour of waste water due to the presence of organic and inorganic pollutants..
