In this research, a plant material (Strychnos potatorum seed powder) has been used as natural coagulants, and tested the ability to remove turbidity from synthetic water and industrial water samples. The results from industrial water samples were compared with synthetic water samples. Experiments have been conducted in the laboratory to assess the percentage (maximum) of turbidity removal at various levels (i.e., 50, 80, 110, 120, and 145 NTU) from collected and prepared samples. Parameters influencing the coagulation mechanism such as dosage and pH were reported most suitable parameters for maximum turbidity removal. In this regard, the percentage of turbidity removal varies between 46–78% and 50–84% for synthetic and industrial water samples, at an ideal pH level (6–7) respectively. In addition, the isotherm model (i.e., Langmuir and Freundlich) was used to assess the sorption analysis from experimental data sets, wherein the monolayer sorption of contaminants onto the seed powder of S. potatorum was detected. The outcomes highlighted the effect of sorption in the turbidity removal percentage from both synthetic and industrial water samples, advocating the use of S. potatorum as a cost-effective alternative for industrial wastewater treatment.

马铃薯籽粉混凝影响纺织工业排放的参数研究

在这项研究中，一种植物材料（马铃薯种子粉）被用作天然混凝剂，并测试了从合成水和工业水样品中去除浊度的能力。将工业水样的结果与合成水样进行比较。在实验室中进行了实验，以评估从收集和制备的样品中去除各种水平（即 50、80、110、120 和 145 NTU）的浊度百分比（最大）。影响混凝机制的参数如剂量和 pH 值被报告为最适合最大浊度去除的参数。在这方面，合成水和工业水样品的浊度去除百分比分别在 46-78% 和 50-84% 之间变化，在理想的 pH 值水平 (6-7) 下。此外，等温线模型（即 Langmuir 和 Freundlich) 用于评估实验数据集的吸附分析，其中检测到污染物对马铃薯种子粉末的单层吸附。结果强调了吸附对合成水和工业水样品的浊度去除百分比的影响，提倡使用马铃薯作为工业废水处理的经济有效的替代方案。
