Etude de l'impact des eaux usées industrielles sur Oued Reghaia et oued El Biar et proposition de traitement.

Abstract

The objective of our project consists in dimensioning a collective industrial wastewater treatment plant in the municipality of Réghaia, which will treat all the wastewater produced by this industrial zone, their quantities are estimated at about 50000 m3/J. And this in order to preserve the environment and public health. This study deals with two main aspects : The first one consists in studying the characteristics of this industrial wastewater; the results obtained showed that we are facing a water very loaded with pollutants and of a nature that is not easily biodegradable. The second part concerns the dimensioning of the collective ERI wastewater treatment plant based on the analyses of the industrial wastewater directly discharged into Wadi Réghaia and Wadi El Biar.
