“…The presence of oil in the seed will affect the coagulation process and this confirmed the reason for the oil extraction process conducted. Moreover, the presence of the oil will increase the quantity of organic matter added to water as reported by Garcia-Fayos et al, (2016). Eman et al(2014) also buttressed this and reported that the performance of the Moringa oleifera cake residue in water treatment process will decreases as the oil content in the Moringa oleifera cake residue increases (Eman et al, 2014).…”

Inrecent times, the consumption of water for domestic and industrial use has been on an increasing trend with a rise in demand. Therefore, a need for a plant-based alternative of water treatment process at a lower cost using an environmentally friendly approach. Moringa olifeira is an example ogf the plant-based materials usually grown in developing countries with a natural coagulating property. In this study, the Jar test was conducted to evaluate the performance of Moringa olifeira cake residue (MOCR) as biocoagulant for the treatment of water for safe drinking. The result obtained showed the lowest turbidity, pH, TDS, and water conductivity value as 4.7 NTU (0.75 mg/L), 5.2 (2.5 mg/L), 40 ppm (1.0 mg/L), and 50us/cm (0.50 mg/L), respectively. Moreover, the standards COD and BOD values were less than the recommended Malaysian Standard of Water Quality of 250 mg/L and 100 mg/L, respectively. Hence, MOCR therefore is a potential source for plant-based coagulating agent for water treatment for domestic drinking water.

“…Asimismo, es observado un incremento de DQO y DBO 5 soluble por adición del coagulante natural, esto se debe a la naturaleza orgánica del mismo, el cual contiene de 30-40% de aceites (Garcia-Fayos et al, 2016). Comportamiento distinto es observado usando el sulfato de aluminio, el cual presenta incrementos en el DQO particulado.…”

“…La previa extracción de aceites y grasas de la semilla de M.O, permitió incrementar las eficiencias de remoción de turbidez, SST, DBO 5 y DQO, además se observó una disminución de dosis de coagulante (0.5 g/L). Estos resultados son coherentes con lo reportado por Garcia-Fayos et al (2016), quienes incrementaron las eficiencias de remoción de turbidez con el coagulante de semilla de M.O, mediante previa extracción con etanol en el equipo Soxhlet. Sin embargo, Camacho et al (2016) reportaron que no existen diferencias entre el uso de la semilla de MO con y sin previa extracción, en el tratamiento de agua con una turbidez inicial de 30-60 NTU, alcanzando remociones de este parámetro de hasta 90%.…”

<p>El presente trabajo evalúa la eficiencia del uso de la Moringa oleífera (M.O) como coagulante en el tratamiento de aguas de alta turbidez y carga orgánica. Inicialmente los resultados demostraron que el coagulante a base de las semillas de M.O pre-tratada con cloruro de sodio (NaCl 1.0 N) y usando una dosis de 0.74 g/L, alcanza remociones de 87.3% y 88.8% para turbidez y sólidos suspendidos totales (SST), asimismo valores de 25.9% y 26.3% para DBO5 y DQO respectivamente. En una segunda etapa, el coagulante, sometido a extracción Soxhlet y dosis de 0.5 g/L, muestran máximas eficiencia de 97.8%, 89.99%, 51.4% y 35.3% en la remoción de turbidez, SST, DQO y DBO5. Las más altas eficiencias obtenidas fueron alcanzadas mediante la previa extracción de aceites, grasas y otros componentes de la semilla de M.O. Estudios relacionados al reaprovechamiento de sub-productos de la extracción deben ser realizados.</p>

“…The reduction of BOD is significant as it allows for safe storage of the treated water. BOD can be reduced by extracting the oil from the seeds before powdering them (Garcia-Fayos et al, 2016). Using ethanol as a solvent and the Soxhlet procedure (Method 3540C, 1996), the oil can be extracted from the seeds.…”

“…Using ethanol as a solvent and the Soxhlet procedure (Method 3540C, 1996), the oil can be extracted from the seeds. The oil can be used for industrial purposes, and the seed powder is more efficient at treating water (Garcia-Fayos et al, 2016). The powdered seeds are the most known and researched method of water purification, however, there is also anecdotal evidence that leaves have been traditionally used in this role as well.…”

Chemical and antimicrobial properties of Moringa (Moringa oleifera) root and its impact on water quality

Moringa oleifera is a tropical tree with nutritious, anti-inflammatory, and antimicrobial properties. Moringa seeds have been studied for their ability to purify water, however roots have not. This study identified the nutrient composition of Moringa roots grown in a greenhouse, and tested whether the roots improved water quality. Moringa roots were dried, powdered and added to contaminated water to test their impact on E. coli, pH, turbidity, and electrical conductivity. The chemical composition of Moringa roots were measured using ICP-MS. The five main elements observed were potassium, phosphorus, magnesium, sodium and calcium. None of the elements extracted were of health concern for drinking water quality. Electrical conductivity and pH remained within drinking water quality guidelines. Moringa root powder resulted in a significant increase in turbidity. Moringa concentration of 600 mg/L removed up to 87% of E. coli in water.Moringa root powder shows some potential as a point-of-use water treatment.
