Most domestic wastewater in urban and rural centers is dismissed without prior treatment or in the sewage system or directly into the aquatic environment. This often causes an alteration and a biological imbalance. In this study we will work on the natural lagoon treatment plant wastewater city of Dar ElGueddari with a nominal capacity of 700 m3/ day.
The present work aims to:
Analyze the results of monitoring campaigns carried out at the entrance and exit of STEP in 2012-2013 for pollution parameters BOD5, COD and TSS.
Analyze the purification performance of the station and offer recommendations to improve their treatment efficiency according to national standards or European.
Furthermore, we will also perform a qualitative analysis through:
The evaluation of the quality of the effluent based on domestic Moroccan discharge standards and compliance in terms of BOD5, COD and TSS.
The confirmation of the characteristic of waste water by comparing the DCO reports/BOD5 and TSS/BOD5 with the usual ratios of urban wastewater.
Comparison of the abatement of pollution parameters compared to those set by the European directive.
