The main objective of this study is to confirm the potentials of Moringa oleifera seeds over alum for water purification. Various doses of Moringa seed powder 4, 8, 12 g/l were taken and checked for treatment of river and sewage water. After treatment of seed powder with water samples were analyzed for physico-chemical parameters like pH, Absorbance, TDS, TSS, Hardness, Chlorides, Conductivity, Turbidity, MPN and DO. Almost all parameters showed reduction with increasing dosage of Moringa seed powder. Similar doses of alum were checked with river water sample and were analyzed for above mentioned parameters. The results obtained showed that seed powder (natural coagulant) is more effective than conventional chemical coagulant., alum. The seed of Moringa oleifera is cheap, eco-friendly and non-toxic, can be effectively used as a coagulant for river and sewage water purification.

Wastewaters from textile industries are known for their difficulty to treat, several alternative technologies are applied for their treatment. In this context, the study examined a hybrid treatment system, composed of electrocoagulation combined with a natural coagulant (extract of Moringa oleífera lam seeds) to remove reactive dye Blue 5G aqueous solutions. The work evaluated the use of milder operating conditions to improve the efficiency of treatment, with reduced demands for electrical power and coagulant.  The following factors were evaluated: electric current intensity, natural coagulant concentration and hydraulic retention time. A quadratic model was adjusted and validated at a 5% significance level. The overall optimization resulted in conditions of 0.28 A for electrical current intensity, 1000.00 mg L-1 of aqueous extract of Moringa oleífera lam and 5 min for hydraulic retention time. While operating under optimal conditions, the removal of 71.38% of color and 5.22 mg L-1 of iron residual concentration was achieved.

This study evaluated the use of Moringa oleifera (MO) seed as a natural coagulant for the removal of turbidity and apparent color in the water treatment with low initial turbidity through the in-line filtration technique. The morphology and surface charge were investigated by characterization techniques such as optical microscopy, laser particle size, and zeta potential. The cationic proteins of the MO seed were extracted in aqueous solution. The jar test showed the potability standards for turbidity and apparent color were reached in the pH range from 4.0 to 8.5 and dosages ≥ 5 mg L-1 of MO. The dominant coagulation mechanism is adsorption and charge neutralization. This study showed that treating low-turbidity water with MO seed by the in-line filtration technique is possible.

Before And After

Two methods of treating water using a natural coagulant and a chemical coagulant were assessed. The natural coagulant was Moringa oleifera seeds (a forest plant) i.e Treatment ‘A’ while the chemical used was Aluminum hydroxide chloride i.e Treatment ‘B’. The aim of this study was to compare the use of a natural coagulant with a chemical coagulant.  Samples were collected at Omida,  Ibara, Mama Cass, Mr Bigg’s and Sidipon village respectively. The filtrate of   Moringa oleifera seed extract was dosed into the greywater sample at 10% dosing range and made to run through a greywater treatment plant while Aluminum Hydroxide Chloride was also dosed at 10% dosing range and made to run through the treatment plant respectively. The greywater treatment plant   is a self designed treatment plant made to treat both water and wastewater. The raw water was firstly analyzed, after which the treated samples were taken to the laboratory for analysis.  Result for the physical, chemical and bacteriological analysis of treatment ‘A’ before and after treatment were as follows: pH (9.3, 9.7), EC (2995, 1175μs), Temperature (27.7, 27.6oc) , TDS (365, 155ppm),  TSS (0.32, 0.30ppm), TS (376, 155ppm), Sulphate (588, 314mg/l), Magnesium (400, 260mg/l), Nitrate (7.5, 6.1mg/l), Phosphate (285, 12mg/l) and total coliform count after treatment is given as (2.8x103 cfu/ml), while that of treatment ‘B’ before and after treatment were as follows: pH(11, 9.9), EC (3000,630), Temperature (27.7, 27.6oc), TDS (0.47, 0.45ppm), TS (416, 320ppm), Sulphate (571, 246mg/l), Magnesium (820,  860mg/l), Nitrate (4.4, 6.0mg/l), Phosphate(169, 6.1mg/l)  the  total coliform count after treatment was  given as ; (3.0x103cfu/ml). One-way Anova test was used to determine differences between results obtained using the two coagulants. The result indicated no significant difference at p=0.05 between the two treatments. Hence, result was further compared with World Health Organization Standard for Drinking Water.  Comparatively, the analysis obtained from water treated with Moringa oleifera was found to be more effective than the chemical coagulant, and can be easily made available for the use of the populace.

The coconut desiccant industry produces wastewater with high concentrations of suspended solids and turbidity, resulting in negative impacts to the environment if discharged without adequate treatment. The wastewater produced requires appropriate flocculant and coagulant compounds for treatment via the clarification process. Commercial coagulants raise many environmental concerns pertaining to the release of toxic metal residues and traces of chloride and sulphate ions in the treated water. The use of eco-friendly coagulants as an alternative for commercial coagulants in wastewater treatment is on the rise. Several factors that influence clarification performance during treatment includes coagulant dosage, flocculant dosage, and mixing rate of coagulation–flocculation process. The aim of this research is to analyze the effectiveness of using a natural coagulant, Moringa oleifera extract in the removal of suspended solids and turbidity from the coconut desiccant industry wastewater. The Response Surface Methodology approach was used to optimize the concentration of coagulant and flocculant dosed along with mixing rate. The results were measured as maximum percentage removal of suspended solids and turbidity. Coconut desiccant wastewater was collected over a period of five days. Moringa extract was produced via dilution of fat free Moringa seed powder with salt solution at a fixed ratio. The percentage removal of both suspended solids and turbidity was in the range of 85.4–95.1% and 85.2 to 94.8% respectively, based on multiple jar tests conducted. The model generated for optimization is a quadratic model. The optimization produced an optimum point of treatment, which is 12.00 mg/L of Moringa extract as coagulant, 12.660 ml/L of anionic polymer as flocculant and a mixing rate of 90 revolutions per minute, resulting in 93.997% and 93.735% removal of suspended solids and turbidity, respectively, proving a successful treatment of coconut desiccant wastewater.
