During 6 months, samples were taken every month to study the Physico-chemical parameters of this station. Monthly monitoring of SS, COD, BOD5 was made from September 2017 to February 2018 and the results obtained show that the average elimination rates were 77.76, 74.10 and 80% respectively for BOD5, DCO and SS. The average of the ratio COD/BOD5 during the 6 months of follow-up is equal to 2.9.enSS, COD, BOD5, purification station, pollution, Physico-chemical parametersArticle
