Abstract & Overview
The working conditions during the preparation and extraction of solvents from various plant parts significantly improved plant-based coagulants used in water treatment. The study reviews the performance of plant-based coagulants in reducing turbidity, total hardness, heavy metals, and microorganisms, emphasizing dosage variations across different plant types. Utilizing specific keywords for searching plant-based coagulants status and organizing data into descriptive analysis were applied. The preparation process results of plant-based coagulants involved particle size, mixing speeds, drying temperature and time were presented. Again, performance results of the plant-based coagulants indicated the average turbidity removal performance ranged between 78 and 87.3%, heavy metal removal ranged from 59 to 98%, hardness reduction ranged from 15.45 to 43.3%, and microbial elimination ranged from 91 to 92% using solid dosage levels ranged from 0.5 to 10.3 g/L and liquid dosage level ranged from 2 to 54 mL/L, respectively. The actionable suggestions for implementing plant-based coagulants for up scaled in water treatment systems were presented. Therefore, the findings would support the optimization of dosage level from various plants for commercialization in water treatment applications.
