Abstract


In order to preserve the quality of water masses and reduce the deterioration of the natural environment, alternative water supplies should be required. The reuse of treated wastewater seems to be a good alternative in agriculture. Our study focuses on the characterization of the physico-chemical effluents (pH, EC, Turbidity, SS, COD, and BOD5) in treated wastewater of M’zar plant in Agadir during one-year cycle. It aimed to study the evolution of these parameters over five years since 2006 in compliance with discharge standards in the natural environment and concerning the safety of water for irrigation. It has been shown that the quality and quantity of wastewater depends essentially on the amount of water consumed by the population, the intensity of industrial activities and tourism according to the seasons. The removal percentage of particulate pollution and oxidizable parameters already mentioned were very satisfactory and range from an average of (97 to 99%). The rate of the Electrical Conductivity (EC) does not change between input and output of plant. The treated wastewater characterized by a high EC (between 3 and 4 dS/m) and it can be a problem for reuse in irrigation.
