The aim of the present work is to investigate the potential use of banana peel waste as a natural coagulant and to enhance its coagulation performance using a green modification approach for the removal of synthetic water turbidity and river water treatment. Here, the regular banana peel powder had an average particle size and diameter of 978 ± 37 nm and 602 ± 13 nm, respectively, while the modified powder possessed 571 ± 41 nm and 360 ± 19 nm particle size and diameter, respectively. The coagulation performance was investigated at different pH levels, doses, sedimentation times, and NaCl quantities. The optimum dose was found to be 0.4 g/L for modified banana peel with turbidity removal of up to 90%. NaCl slightly enhanced the coagulation performance at low quantities of less than 0.4 g/L, but the activity was reduced at higher concentrations even in the modified powder. Banana peel powder had a weaker turbidity reduction of 76 and 84% for non-modified and modified powders in river water, respectively, in addition to significant reduction in water color, total dissolved and suspended solids, and chemical and biochemical oxygen demand. SEM and FT-IR characterization were performed to investigate and confirm the coagulation mechanism. Such a green modification of banana peel powder can be an alternative with significantly potential as a low cost and easily available bio-coagulant, which can certainly contribute to the waste reduction.

提高香蕉皮生物混凝剂在浊水和河水处理应用中的效率

本工作的目的是研究香蕉皮废料作为天然混凝剂的潜在用途,并使用绿色改性方法提高其混凝性能,以去除合成水浊度和河水处理。在这里,普通香蕉皮粉的平均粒径和直径分别为 978 ± 37 nm 和 602 ± 13 nm,而改性粉的平均粒径和直径分别为 571 ± 41 nm 和 360 ± 19 nm。在不同的 pH 值、剂量、沉降时间和 NaCl 量下研究了混凝性能。改性香蕉皮的最佳剂量为 0.4 g/L,浊度去除率高达 90%。NaCl 在低于 0.4 g/L 的少量下略微增强了混凝性能,但即使在改性粉末中,活性也会在较高浓度下降低。除了显着降低水色、总溶解和悬浮固体以及化学和生化需氧量外,香蕉皮粉对河水中的未改性和改性粉末的浊度分别降低了 76% 和 84%。进行 SEM 和 FT-IR 表征以研究和确认凝血机制。这种香蕉皮粉的绿色改性可以作为一种具有显着潜力的替代品,作为一种低成本且易于获得的生物凝结剂,这肯定有助于减少废物。除了显着降低水的颜色、总溶解和悬浮固体,以及化学和生化需氧量。进行 SEM 和 FT-IR 表征以研究和确认凝血机制。这种香蕉皮粉的绿色改性可以作为一种具有显着潜力的替代品,作为一种低成本且易于获得的生物凝结剂,这肯定有助于减少废物。除了显着降低水的颜色、总溶解和悬浮固体,以及化学和生化需氧量。进行 SEM 和 FT-IR 表征以研究和确认凝血机制。这种香蕉皮粉的绿色改性可以作为一种具有显着潜力的替代品,作为一种低成本且易于获得的生物凝结剂,这肯定有助于减少废物。
