Abstract

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