Parasitological assessment of the purifying performance of the wastewater station by natural lagoon of Azilal, Morocco.
In the context of saving human health against waterborne diseases, the present work is interested in the study of some parasitological characteristics of raw and treated wastewater from the treatment station of Azilal city. The purpose of the analysis is to determine the parasite load, hence the abatement of the station, the samples analyzed were taken between August 2013 and May 2014, aimed to detect the presence of eggs of some parasites, the examination of the latter was based on the technique of Bailenger. Furthermore, for raw wastewater at the station entrance, the results revealed the presence of Helminth’s eggs with a load of 39.3 eggs/l. The phylogenetic study isolated three different classes: Nematodes, Cestodes, and Strongles respectively with a load of 27.7, 7, and 4.6 eggs/l. However, the distribution of these collected eggs shows that the Nematode class is most represented with five species, followed by the Cestodes class with three species. For treated wastewater at the station exit, we isolated Helminth’s eggs at an average concentration of 3.6 eggs/l of which 2.7 eggs/l correspond to Nematode, 0.5 eggs/l at Cestodes, and 0.4 eggs/l at Strongles. In light of these results, it can be said that the station does not ensure the total elimination of Helminth’s eggs. These results remain far from those encountered in the literature.
