Description
Summary:The main objective of this work is to analyze the possible use of banana peel waste as a natural coagulant and also to improve its coagulation effectiveness using an eco-friendly modification methodology the removal of synthetic water turbidity and river water purification. In this case, the modified banana peel powder hasan average particle size and diameters are 571 and 360 nm respectively. While the normal banana peel powder’s size of particles and diameter were 978 and 602 nm, respectively. The effectiveness of the coagulation was examined at various pH values, dosages, sedimentation periods, and NaCl concentrations. With up to 90% turbidity removal, the ideal dose for modified banana peel was discovered to be 0.4 g/L. At small concentrations of less over 0.4 g/L, NaCl somewhat improved the coagulation performance; however, the activity decreased at higher concentrations, even when using the modified powder. In river water, banana peel powder act significantly hence reduced the color of the water, the total amount of dissolved and suspended solids, as well as the chemical and biochemical oxygen demand. However, for non-modified and modified powders, the turbidity reduction was only 75 and 83%, respectively. To look into and validate the coagulation mechanism, SEM and FT-IR analysis were done. Banana peel powder modified in this environmentally friendly way has a lot of potential as a cheap and accessible bio-coagulant and can likely help to decrease wastages.
