Treatment of Wastewater by Moringa Oleifera and Maize Seeds as Plant-Based Coagulant

Abstract Coagulants are essential in purifying raw water for drinking safety consumers. Commonly, aluminium sulphate, a chemical coagulant, is used treatment. However, long-term usage, coagulants can be considered toxic and harmful to the environment due accumulation of this substance pipeline system, which create severe health issues if consumed. The natural plant-based coagulant substitute sustainable solution treatment coagulation process. This research aimed determine efficiency materials as surface Moringa oleifera maize seeds were chosen investigation since they both locally available materials. Here, aims study ability moringa seed enhancing effluent quality wastewater plant UiTM Dengkil Selangor. A jar test experiment was assess capacity coagulants. results comprise turbidity removal by 92% (mixed seed), oxygen demand (COD) 95% reduction rate using seed. biochemical (BOD) 88% seed, ammonia-nitrogen 12% (moringa seed) total suspended solids (TSS) 100% mixed sample. Thus, it recognized that an alternative replace systems.
