چکیده
Abstract The present study aims to fill the data gap analysis in urban wastewaters characteristics Benin and its statistical analysis. Physicochemical parameters such as pH, electrical conductivity (EC), Chemical Oxygen Demand (COD), Biochemical (BOD5), Total Kjeldahl Nitrogen (TKN), Phosphorus (TP) UV Absorbance at 254 nm, were determined on domestic (greywater blackwater) industrial (hospital, pharmaceutical commercial laundry) wastewater Cotonou city. Analysis of variance showed a strong significant difference physico-chemistry various effluents. has highest concentration organic pollution (COD = 5,912 ± 1,026 mg/L, Abs.UV254 2.667 0.327 cm?1). load blackwater is mainly particulate biodegradable form. Besides, correlation limits pH EC an indicator load. Furthermore, choice COD or BOD5 main design parameter would be limited treatment. was found having relationship with other all effluents except blackwater. It then takes priority over for treatment greywater wastewater. For future plant design, we recommend consider important parameter.
