In this laboratory based study, varying quantities of oil, corresponding to 20 % w/w, 25 % w/w and 30 % w/w kernel weight extracted from Moringa oleifera seeds ( S1, S2, S3) respectively  were applied in the coagulation of model turbid water (kaolin suspension) and turbid river water samples from River Batang Kali and River Selangor in Malaysia to determine the percentage oil removed which gave the best coagulation efficiency. For model turbid water (kaolin suspension) coagulation of low turbidity of 35 NTU, medium turbidity of 100 NTU and high turbidity of 300 NTU, sample S2  gave the best turbidity removal corresponding to 91.7%, 95.5% and 99% respectively. Application of sample S2 to River Batang Kali with low initial turbidity of 32 NTU and high initial turbidity of 502 NTU gave a highest turbidity removal of 69% and 99% respectively. Application to River Selangor with medium initial turbidity- of 87 NTU and high initial turbidity of 466 NTU gave a highest residual turbidity' of 94% and 98.9%,  respectively.Key words: Moringa oleifera seed, selective oil extraction, coagulation, model turbid water (kaolin suspension), river water, turbidity removal.

Moringa Oleifera Seed

The plant-based natural coagulant has the potential to substitute the chemical coagulant in the water treatment process. In this work, the potential of plant-based natural coagulants in the ability of turbidity removal was identified. The Moringa oleifera seed was selected for the batch analysis test such as pH, contact time, agitation, and dosage. The high alkaline water decreases the effectiveness of plant-based natural coagulants. The agitation and contact time show the importance of the coagulation process. The optimum turbidity removal rate in pH is 4, the contact time is 60 seconds and 3000 seconds for coagulation and flocculation, respectively, the agitation is 300 RPM and 30 RPM for coagulation and flocculation, and lastly, the dosage is 10 g of Moringa oleifera seed. Finally, the plant-based natural coagulants demonstrated the ability to remove turbidity and could be used in place of chemical coagulants.

In this study the performance of biocoagulant based on protein (Moringa oleifera, Vigna sinensi) and tannin (Colocasie esculenta) was compared with Poly Alumunium Chloride (PAC) as a chemical coagulant have been evaluated using a synthetic kaolinite-turbid water which referred to water sample. The effectiveness of biocoagulants dosage were evaluated by turbidity removal (%), total dissolved solid TDS and electrical conductivity (EC). The results showed that the turbidity removal of water sample achieved as much as 94.4% and 87.0% for Moringa oleifera and Vigna sinensi, but low turbidity removal occurred when using Colocasia esculenta as much as 26.4%. High results of turbidity removal showed when using PAC as coagulant at different dosages as a comparison. The decreasing of TDS and EC in the water sample did not much influenced by the coagulants except for Vigna sinensi.

Seed Extracts

The effects of Moringa oleifera seed extracts' deterioration and preservation on turbidity removal efficiency were studied. Trona was used as a preservative in the enhancement of the extract's shelf life. An average value of 92.30% was observed at the Moringa oleifera seed extracts' dosage of 800 mg/L as the highest average turbidity removal for all the extracts, while the least value 82.16% was observed at a dosage of 320 mg/L. The fresh preserved Moringa oleifera seed extract had a value of 95.18% as the highest average percentage turbidity removal against all the extracts for all dosages, while the plain extract had the lowest average percentage turbidity removal value of 74.93%. It was observed also that even though the preserved extract was the most consistent in turbidity removal (overall variance of 1.25), the fresh preserved extract had the overall highest performance. However, the difference in overall performance between the two was only marginal, while substantial difference was observed between the plain extract and the fresh plain extract.

Aims: The use of natural, on-site, low-cost coagulants can reduce problems related to the consumption of non-potable water and untreated wastewater discharges into receiving bodies. A natural solution for acting as a coagulant is the Moringa oleifera seed. The objective of this study is to analyze the efficiency of turbidity removal through the application of moringa seeds as a natural coagulant in three different retention times. Methodology: The research was carried out at the Agricultural Products Storage Processing Laboratory of the Federal University of Campina Grande. The powder obtained after trituration of the seeds and the seed without bark was used. A jar test was used to test the application of the coagulant based on powder and moringa seeds. To obtain artificial water, 0.5 g of clay was added to the jars of the jar test. The Jar Test was connected to a rotation of 120 rpm for 30 minutes, then was turned off and kept at rest for 45, 53 and 61 minutes. Subsequently, approximately 50 mL of sample was collected from each pitcher for analysis of the turbidity parameter. Results: The application of the seeds was more efficient than the powder. Sedimentation times influenced the removal of turbidity. Conclusion: The turbidity values are outside of what is allowed by current Brazilian legislation.

Controlled Conditions

Samples of turbid water prepared under laboratory controlled conditions were tested using natural coagulant-flocculant Moringa oleifera seeds from Burundi, Central Africa, and from Mahajanga, Madagascar. Coagulation-flocculation and sedimentation experiments were conducted using jar test equipment. For these tests, 5% Moringa oleifera solutions (w/w in water) were prepared using shelled and non-shelled seeds from the aforementioned countries. The results show that, in both cases, the shelled seeds provide much higher turbidity removal than the non-shelled ones. In addition, the volume of sludge produced was approximately 30% of that of conventional coagulants such as alum. Finally, it was concluded that seeds from Burundi were of superior quality than those of Madagascar. In fact, higher dosages of these seeds, of up to four times, were required in order to attain the same level of turbidity as the Burundi seeds.
