This research aims at process optimization using response surface methodology (RSM) for coagulation of surface water by coagulants extracted from natural product. Apricot seeds extract (ASE), peach seeds extract (PSE) and mango seeds extract (MSE) were evaluated. The optimum operating conditions for ASE and PSE at initial turbidity of 27.5 NTU were pH 7 and coagulant dose of 45 mg/l. However, the optimum operating conditions for MSE at initial turbidity of 27.5 NTU were pH 5.5 and MSE dose of 45 mg/l. Under the optimum conditions, residual turbidity without filtration was 9.13, 10.3, 5.81 NTU for ASE, PSE and MSE, respectively. MSE could be used as secondary coagulant with the alum. At low turbidity surface water treatment, ratios of 20/80, 40/60 and 60/40 MSE/alum achieved residual turbidity of less than 1 NTU which comply with the Egyptian Standards. However, at medium turbidity surface water, ratio of 20/80 MSE/alum achieved residual turbidity of less than 1 NTU.

用于地表水凝结的天然产品:农村地区的替代可持续解决方案

本研究旨在使用响应面法 (RSM) 优化过程,以通过从天然产物中提取的凝结剂凝结地表水。对杏子提取物 (ASE)、桃子提取物 (PSE) 和芒果种子提取物 (MSE) 进行了评估。ASE 和 PSE 在初始浊度为 27.5 NTU 时的最佳操作条件是 pH 7 和凝结剂剂量为 45 mg/l。然而,MSE 在初始浊度为 27.5 NTU 时的最佳操作条件是 pH 5.5 和 MSE 剂量为 45 mg/l。在最佳条件下,ASE、PSE和MSE未经过滤的残留浊度分别为9.13、10.3、5.81 NTU。MSE可与明矾一起用作二次混凝剂。在低浊度地表水处理中,比率为 20/80,40/60 和 60/40 MSE/明矾达到低于 1 NTU 的残余浊度,符合埃及标准。然而,在中等浊度的地表水中,20/80 MSE/明矾的比例实现了小于 1 NTU 的残余浊度。本研究旨在使用响应面方法(RSM)通过从天然产物中提取的凝结剂凝结地表水来优化过程。杏子提取物 (ASE)、桃子提取物 (PSE) 和芒果籽提取物 (MSE) 被评估为用于地表水处理的低成本天然混凝剂。在最佳条件下,ASE、PSE和MSE的未过滤残留浊度分别为9.13、 10.3、5.81 NTU。MSE可与明矾一起用作二次混凝剂。在低浊度表面水处理中,比率为 20/80,40/60 和 60/40 MSE/alum 达到了小于 1 NTU 的残余浊度,符合当地标准。这项研究旨在使用响应面法(RSM)对地表水的凝结进行工艺优化,通过提取的凝结剂来自天然产品。杏子提取物 (ASE)、桃子提取物 (PSE) 和芒果籽提取物 (MSE) 被评估为用于地表水处理的低成本天然混凝剂。在最佳条件下,ASE、PSE和MSE的未过滤残留浊度分别为9.13、 10.3、5.81 NTU。MSE可与明矾一起用作二次混凝剂。在低浊度表面水处理中,20/80、40/60 和 60/40 MSE/明矾的比例实现了小于 1 NTU 的残余浊度,符合当地标准。这项研究旨在使用响应面方法(RSM)通过从天然产物中提取的凝结剂凝结地表水来优化过程。杏子提取物 (ASE)、桃子提取物 (PSE) 和芒果籽提取物 (MSE) 被评估为用于地表水处理的低成本天然混凝剂。在最佳条件下,ASE、PSE和MSE的未过滤残留浊度分别为9.13、 10.3、5.81 NTU。MSE可与明矾一起用作二次混凝剂。在低浊度表面水处理中,20/80、40/60 和 60/40 MSE/明矾的比例实现了小于 1 NTU 的残余浊度,符合当地标准。这项研究旨在使用响应面方法(RSM)通过从天然产物中提取的凝结剂凝结地表水来优化过程。杏子提取物 (ASE)、桃子提取物 (PSE) 和芒果籽提取物 (MSE) 被评估为用于地表水处理的低成本天然混凝剂。在最佳条件下,ASE、PSE和MSE的未过滤残留浊度分别为9.13、 10.3、5.81 NTU。MSE可与明矾一起用作二次混凝剂。在低浊度表面水处理中,20/80、40/60 和 60/40 MSE/明矾的比例实现了小于 1 NTU 的残余浊度,符合当地标准。桃子提取物 (PSE) 和芒果籽提取物 (MSE) 被评估为用于地表水处理的低成本天然混凝剂。在最佳条件下,ASE、PSE和MSE的未过滤残留浊度分别为9.13、 10.3、5.81 NTU。MSE可与明矾一起用作二次混凝剂。在低浊度表面水处理中,20/80、40/60 和 60/40 MSE/明矾的比例实现了小于 1 NTU 的残余浊度,符合当地标准。桃子提取物 (PSE) 和芒果籽提取物 (MSE) 被评估为用于地表水处理的低成本天然混凝剂。在最佳条件下,ASE、PSE和MSE的未过滤残留浊度分别为9.13、 10.3、5.81 NTU。MSE可与明矾一起用作二次混凝剂。在低浊度表面水处理中,20/80、40/60 和 60/40 MSE/明矾的比例实现了小于 1 NTU 的残余浊度,符合当地标准。
