Effectiveness of Moringa oleifera (Malunggay) Seeds as Coagulant

Abstract

INTRODUCTION

Water is of major importance to all living things. Some residents still rely on unsafe and unsustainable water until now. Several studies are being conducted to provide solutions on how people can gain access to clean water, specifically in remote areas. However, most studies are costly and inaccessible. This predicament leads people in rural and isolated areas to use contaminated water. It was in this light that the researchers aim to enhance a cost-effective solution. Moreover, this study aims to determine the effectiveness of Moringa oleifera (Malunggay) seeds in filtrating water with different substances. As such, the researchers have provided valuable ideas on economical yet effective water treatment for the community.

METHODS

Researchers used quantitative analysis as this study involves numeric information in the form of variables. An experimental research design was also used for this study. The water samples were gathered from river water and piggery drainage water. The physicochemical properties tested were pH level, turbidity and Biochemical Oxygen Demand (BOD). Three amounts of malunggay seeds (0.1g, 0.3g, and 0.5g) were used to distinguish the number of seeds that best suit its ability as a coagulant. The results of the water testing were then analyzed and were compared to the standard physicochemical properties of domestic water.

RESULTS

Through experimentation and water testing, the researchers were able to gather enough data to conclude that Malunggay seeds can be considered as a cost-effective natural coagulant and can be used to clarify water, with 0.1g as the most effective amount of seeds. It is proven that there is no significant difference in the properties of the treated water samples and the properties of standard water for household and domestic purposes with the BOD level as an exception. Therefore, the change on the physicochemical properties of the water samples after being treated with malunggay seeds does not affect its capability of being used for household or domestic purposes.

DISCUSSIONS

The results have proven that malunggay seeds can be considered as an alternative natural coagulant that can clarify water which can be used for domestic and household purposes. Further studies may be conducted about the overall properties that make it suitable as a coagulant. This study can serve as a reference in making another research that explores the number of seeds that is best suitable for water treatment other than the amount used in this study.
