Résumé:
Wastewater is treated by purification in dedicated plants. Before any domestic or industrial
wastewater is treated, its composition must be known. This allows us to know which chemical
and biological elements are present and to provide the necessary information to design the
appropriate treatment.
The objective of this study, which was conducted on the results of analyzes obtained during
two months (March and April) in 2023 of pH, COD, Suspended solids, BOD, and other factors,
is to assess the wastewater performance and quality of the wastewater treatment plant in the
town of Ain Taghrout, which uses the activated sludge method. Our study showed that the
values found meet discharge standards. Ain Taghrout’s WWTP generates a good
performance : 93.64% of SIS and 91.72% of BOD5.
