Study of wastewater treatment for an agricultural reuse

Abstract

In the framework of sustainabledevelopment, it is imperative to rationalize the useof water resources conventional and unconventional. That is why the re-use agricultural of by-products of the treatment is an alternativeexpected to preserve the environment and promotion of the agricultural sector. The present work aims to characterize sludge andthe treated waters of the WWTP of Medea and assess their potential and fitness for agricultural use. The physico-chemical and bacteriological results revealed that for sludge, the C/N foundindicates important nitrogen availability. This report is related to the low amount of organic matter it contains. For treated water of the WWTPto the current state are highly charged with fecal coliforms and can not be reused withoutchlorination and their high salinity limits theirreuse for certain crops...
