Conception d'une station d'épuration par lagunage aéré de la ville de Khemisti (w. Tissemsilt)

Abstract

Domestic wastewater from the city of KHEMISTI is discharged directly into the wadi, which presents a great danger to human health and the environment, so it is necessary to build a treatment plant in order to protect the receiving environment. The choice of a purification technique depends on several factors, in particular, the population, the flow, the organic load, the cost of operation. The goal of this work is to know the appropriate purification process for this city after a comparative study of two processes, then the sizing of all the works of our station.
