Etude de la possibilité de la réutilisation des eaux usées épurées par lagunage

Abstract

Our work consists of dimensioning a treatment plant for the affection of wastewater for the town of El GOLEA located in GHARDAIA in order to protect public health and the environmental risks of throwing wastewater into the receiving site first, and secondly, ensure a finishing treatment (slow sand filtration) to be reused in irrigation. This station will treat the discharges of the towns: El Meneaa and Hassi el Gara called the town of El Goléa., For this we have proposed a treatment plant by natural lagoon, because on the one hand this process ensures high performance at low cost, and on the other hand, the city of El Goléa by its climatological and morphological situation and by its availability of land presents a set of favorable conditions for the implementation of a lagoon treatment plant.
