“…The results of Katayon et al (2004Katayon et al ( , 2005Katayon et al ( , 2006a and Muyibi and Evison (1995b) indicated that M. oleifera seed extract may not be an efficient coagulant for low turbid water. However, the extract of M. oleifera seed was used to reduce the hardness to 70.00 % as well as turbidity to 99.00 % in hard water (Muyibi and Evison 1995a). Furthermore, the extract efficiency of M. oleifera seed for turbidity removal equals that of alum according to the study conducted by Muyibi and Alfugara (2003).…”

Effects of initial concentrations of Moringa oleifera seed coagulant for removing Chemical Oxygen Demand and Total Dissolved Solids from municipal solid waste leachate have been evaluated at an optimum pH of 7 and temperature of 318 K. The kinetic data obtained from the experiments were fitted to the pseudo first-order, pseudo second-order, Elovich and intraparticle diffusion models. Based on a regression coefficient (R 2 ), the equilibrium (kinetic) data were best fitted with the Elovich model (R 2 = 0.993 for Chemical Oxygen Demand and R 2 = 0.996 for Total Dissolved Solids) than that of other models. The results of the kinetic models study indicated that the adsorption capacity of M. oleifera seed as a coagulant for removing Chemical Oxygen Demand and Total Dissolved Solids in a leachate increased up to 100 mg L -1 , beyond which the adsorption capacity got reduced. Finally, the present study concluded that M. oleifera seed coagulant could be employed effectively for the removal of Chemical Oxygen Demand and Total Dissolved Solids in a municipal solid waste leachate.

“…It has been described as adsorption and charge neutralization (Ndabigengesere et al, 1995;Gassenschmidt et al, 1995) and interparticle bridging (Muyibi and Evison, 1995a). Flocculation by inter-particle bridging is mainly characteristic of high molecular weight polyelectrolytes.…”

“…Berger et al (1984) in a study on the toxicology of M. oleifera seed concluded that it may not constitute a serious health hazard. Muyibi and Evison (1995) suggested that further studies need to be carried out to ensure the complete safety of using M. oleifera in water treatment. Folkard et al (1989) however reported that to date, all the studies have concluded that there is no evidence to suggest any acute or chronic effects on humans, particularly at the low doses required for water treatment.…”

Good quality dry seeds of Moringa oleifera were selected and the seed coat and wings were removed manually. The kernel was ground to fine powder using the coffee mill attachment of the Moulinex domestic food blender. The ground powder was then sieved through 210 µm sieve. The seed powder was de-fatted using hexane in electro-thermal Soxhlet extractor. Moringa seeds extract was obtained using the de-fatted seed cake and aqueous extraction. Different preparations of Moringa extract were added to 10 mL of the Escherichia coli suspension and incubated for 2 h without agitation. Survival of bacterial cells was assessed by making dilution series of bacterial suspensions, plating on nonselective LB medium agar dishes, and incubating for 48 h at 37°C. Duplicates were made of every individual assay. Colonies were counted on dishes and the bacterial cell survival ratio was estimated by comparison to a control experiment where no Moring extract was added. The bacterial removal was optimized by varying the mixing time, mixing speed, and Moringa seeds extract dosage. Statistical optimization was conducted by using central composite design (CCD). The experimental data was analyzed using statistical software DESIGN EXPERT, V6.4.8 DEC 10 2002 for Windows. The response surface model was used to determine the optimum operating condition that yields the highest antimicrobial compounds activities from M. oleifera seeds extracts. A cubic model was fitted to the data. The standard deviation for the cubic model was 0.56, with R 2 = 0.9999 and adjusted R 2 = 0.9994. The analysis of variance (ANOVA) showed that the effects of mixing time, mixing speed and Moringa dosage were significant (p < 0.05) in the extraction process. The Quadratic model was used in predicting the responses and the optimal conditions were determined as 31 min mixing time, 85 rpm mixing speed and 3.25 mg/mL Moringa dosage. The results show that the predicted and experimental values were not significantly different and it was thus concluded that the model obtained can be used to optimize the process of antimicrobial bioactive compound extraction from de-fatted M. oleifera seeds.
