Despite the magnitude of the repercussions generated by the wastewater on the degradation of the Environmental medium, on the water shortage and consequently on public health, in Algeria, little importance is given to sanitation compared with the supply of drinking water services. These sanitation problems remain a major concern and require an supported significant by taking appropriate measures, in perspective to safeguarding and respecting the environment. From the collection to treatment , This wastewater route deserves to be diagnosed in order to control the sanitation system and optimize its facies, by prospecting and research performance indicators, that identify gaps and propose technical solutions for better wastewater management.
For this, we have identified the physicochemical parameters most significant in terms of impact on the receiving environment by analyzing 10 physicochemical variables (Temperature, pH, electrical conductivity, TKN, NO3, NH4+, PO4-, COD, BOD5, TSS) for wastewater from the city of Medea . This study defines the values of mean concentrations, ratios and ranges of variations associated wastewater characteristics. Subsequently, we calculated the ratios of pollution indicators that should enable us to highlight the optimizations necessary to the wastewater treatment plant of Medea.
Keywords : Sanitation, treatment plant, ratios, optimization, performance.
