Abstract
The present study consists in evaluating the quality of the treatment of the STEP of
the city of Kais over the period spread out from 2020 to March 2022.The results
obtained showed that the removal efficiency was satisfactory for particulate matter
and organic matter (93% for SS, 94%, and 91% respectively for BOD5 and COD).
The reduction rate of nitrogen and phosphorus compounds is considered medium to
low. The current results of the parameters measured are satisfactory, but daily
monitoring is lacking for all parameters, as well as toxicity parameters to ensure that
agricultural land is not polluted
