Bench Scale Studies for Pretreatment of Sanitary Landfill Leachate with Moringa Oleifera Seeds Extract

Effectiveness of <i>Moringa oleifera</i> Defatted Cake versus Seed in the Treatment of Unsafe Drinking Water: Case Study of Surface and Well Waters in Burkina Faso

“…Beyond optimal concentration of coagulant, turbidity of treated water increased (Tables 3(a) and (b)). The purifying activities of Moringa oleifera are based on the electrostatic patch charge mechanism [28]. Elimination of fat matter in Moringa oleifera seeds could reduce interactions between lipids and active proteins and could explain the effectiveness of defatted cake in water treatment.…”

Effects of using Tamarindus indica Seeds as a natural coagulant aid in landfill leachate treatment

“…For jar tests using 18% PACl as the main coagulant, the rapid mixing was set at 200 rpm for 3 min and slow mixing at 40 rpm for 30 min; the settlement was 30 min (Zainol et al, 2013). Meanwhile, the operational conditions of the jar tests using TiS as the main coagulant were rapid mixing at 100 rpm for 8 min and slow mixing at 30 rpm for 20 min, and the settlement was 30 min (Muyibi et al, 2002). Leachate samples at 500 mL were filled into six beakers and agitated simultaneously while varying the rotational speed and allowing the simulation of different mixing intensities and resulting flocculation process (Mokhtar et al, 2011).…”

Water Quality Issues and Solutions in Africa

“…Enteric viruses in the past have received less attention compared with bacterial pathogens such as Vibrio cholerae and protozoan parasites (e.g., Cryptosporidium parvum), partly because they are difficult to detect and partly because free chlorine (the main disinfectant used worldwide because of its potency and low cost) was very effective in inactivating those pathogens. Last, halogenated disinfection strategies for treatment and distribution systems produce toxic disinfection by-products (DBPs) such as trihalomethanes and haloacetic acids (Muyibi et al, 2002a). M. avium, in particular, is ubiquitous in biofilms within global water-distribution systems (Shannon et al, 2008).…”

“…The author's laboratory is presently experimenting with two types of filtration and detoxification methods that use clay-doped pots with TiO 2 additives and porous clays with M. oleifera seed extracts (Muyibi et al, 2002a). The primary goal for the future of decontamination is to detect and remove toxic substances from water efficiently and affordably.…”
