Analysis of Physico-Chemical and Bacteriological Parameters of Liquid Effluents from the Provincial Hospital Center in Sidi Kacem Morocco
Keywords:Hospital effluent, bacteriological analysis, physicochemical, environmental impact.
Background: The effluents generated by the hospital activities and which are rejected into the
municipal sewerage system without any prior treatment, present a chemical, biological and physical
risk for public and environmental health. They cause a degradation of the aquatic ecosystem, and favor
the propagation of antibiotic resistant germs. Objective: The aim of this study is to carry out physicochemical
and bacteriological analysis of the effluents of the provincial hospital of Sidi Kacem in Rabat-
Salé-Kénitra region, Morocco, in order to evaluate the degree of wastewater pollution and to reduce its
Methods: 24 samples of wastewater were collected from the Hospital’s main sewer according to
Moroccan Norm NM 03.7.059 and transported to the Provincial Laboratory of Epidemiology and
Environmental Health (LPEHM) for analysis. These analyses were conducted according to the
requirements and methods recommended by Rodier 1996 and 2009.
Results: The results of the bacteriological analysis showed a very high bacterial load of fecal coliforms
(36,7.104 CFU/100 ml), total coliforms (40.104 CFU/100 ml), and fecal streptococci (21.104 CFU/100
ml). The physicochemical parameters revealed a significant load of organic and mineral matter expressed
in terms of nitrates (41,59 mg/l), nitrites (0,53 mg/l), sulphates (222,75 mg/l), ammonia (1,95 mg/l),
electrical conductivity (3202 μs/cm), hydrogen potential PH (7.82), all of which are well above the
upper limit stipulated by the regulations. The COD/BOD5 ratio (7.66) higher than 3 means that these
effluents are hardly biodegradable.
Conclusion: These results show that hospital effluent is loaded with mineral, organic and bacteriological
pollutants and requires
