EPURATION DES EAUX USEES PAR LE PROCEDE SBR DANS UNE AGGLOMERATION DE NAAMA

Abstract

Treated wastewater is an important resource that can be used in many fields (irrigation, industry, etc.). For the treatment, the wastewater treatment plant includes the following stages: pretreatment, primary treatment, secondary treatment, tertiary treatment. In this work, the Naama wastewater treatment plant was dimensioned with the batch reactor Sequencing treatment method. The aim is to verify whether the water leaving this station complies with Algerian standards in order to be reused for the irrigation of agricultural land. The free-culture SBR treatment process, in the same way as the activated sludge process, serves to stabilize the microbiological parameters.
