Physicochemical and Bacteriological Analysis of Wastewater from the Atakpame Regional Hospital Center (TOGO)

Abstract

This study was carried out on the analysis of certain chemical, physical and bacteriological parameters in the wastewaters from Atakpamé Regional Hospital Center (Togo). The methods used for the analysis of the defined parameters are those recommended by “Association Française de Normalisation (AFNOR)” in the field of water analysis. The results revealed the high conductivities in the wastewaters of laboratory and general medicine with 3950 µS/cm, 3870 µS/cm respectively. The chemical oxygen demand (COD) were 3750 mg/L and 1550 mg/L in the surgery and the maternity respectively. The surgery department recorded the high content of biological oxygen demand (BOD) at 946 mg/L. The bacteriological analyses showed the general medicine department was the most polluted area with the presence of total coliforms, thermotolerant coliforms and fecal spectrococci at the concentrations of 40,000, 24,000, 200,000 CFU/mL respectively. The analysis revealed that the wastewater’ parameters exceeded the standards recommended by WHO. Therefore, the wastewaters must be treated before any recovery or use.
