Physico-Chemical and Bacterial Characteristics of Groundwater and Surface Water Quality in the Lagbe Town: Treatment Essays with <i>Moringa oleifera</i> Seeds

Abstract

The river water and groundwater from Lagbe town in Benin Republic were collected and analyzed for physical, chemical and microbiological parameters. The surface water samples were treated with alum, <i>Moringa oleifera</i> seeds powder and the combination of alum and <i>Moringa oleifera</i> seeds. The jar-test essays were carried out with two water samples at initial turbidities 7.2 NTU and 14.4 NTU. The water samples analyzed are fairly mineralized (conductivity varies between 166 and 687 µS/cm), enough soft and contain the nitrate (104 mg/L for W<sub>4</sub> sample). They are greatly polluted by pathogenic microorganisms such as <i>Escherichia coli, Klebsiella, Enterococcus, Vibrio, Serratia. </i> The optimal dosages of <i>Moringa</i> are 96 mg/L and 80 mg/L respectively. We have observed a reduction of 60% of turbidity and a substantial remove of all pathogenic microorganisms after water treatment with <i>Moringa oleifera</i> seeds. For the combination treatment, 93% of initial turbidity and 92% of initial concentration of organic matter in the sample E<sub>2</sub> were eliminated. The pH remained almost constant during the treatment

Physico-Chemical and Microbiological Analysis of Water of the “Presa De Los Patos” in the Desierto De Los Leones National Park, Mexico

“…According to the NOM-127-SSA1-1994, the pH of the drinking water should be between 6.5 -8.5, the water of the dam does not meet the established. Our data is different from those reported by Romeu et al (2012) [30], Torres (2008) [31], Geetha et al (2014) [32], Fatombi et al (2012) [33] that came from another water bodies.…”

Caractéristiques physico-chimiques de l’eau des puits dans la commune de Pobè (Bénin, Afrique de l’ouest)

“…Une eau non potable nécessite un traitement avant sa consommation. Le traitement de l'eau regroupe les principales opérations suivantes : la coagulation, la floculation, la sédimentation, la filtration et la désinfection (Fatombi et al, 2012). Le département du plateau et plus particulièrement la commune de Pobè fait partie des communes les moins desservies par la Société Nationale des Eaux du Bénin (SONEB).…”

Optimization of process conditions in water treatment through coagulation diagrams, using Moringa oleifera Lam and aluminium sulphate

“…It was ascertained the absence of E. coli, which had been already observed by Fatombi et al [17]. Abaliwano et al [8] and Mangale Sapana et al [18] suggest that this can be an indication of bactericidal activity of M. oleifera.…”
