The objective of the present study is to develop eco-friendly purifying agents from natural materials, (SP) - a coagulant. The seeds of SP were used for wastewater treatment (washing machine effluent). Physico-chemical parameters like turbidity, total dissolved solids (TDS), electrical conductivity (EC), pH, calcium (Ca), magnesium (Mg) and phosphate (PO) were tested and the data obtained were compared with BIS standards. In the current work, physical and chemical parameters have been examined to determine the quality of water for washing machine discharge, before and after treatment (coagulation) using SP seeds. The testing procedure was carried out using a Jar test of coagulant mass 1000 mg/L with rapid mixing at 150 rpm for 5 min, slow mixing at 30 rpm for 25 min and a settling period of 1 h. Coagulation results were reported for the use of SP seeds, where the effectiveness of removing turbidity and PO was determined to be 81.54 and 41.45%. The presence of various functional groups in SP seed was assessed by fourier transform infrared (FT-IR) spectroscopy. Qualitative identification of phytochemical constituents of seed extract for this species was also carried out. The experimental findings strongly highlighted the ability of SP seeds to remove turbidity and PO from wastewater.
本研究的目的是从天然材料中开发一种生态友好型净化剂——（SP）一种混凝剂。使用SP的种子对废水（洗衣机废水）进行处理。对浊度、总溶解固体（TDS）、电导率（EC）、pH值、钙（Ca）、镁（Mg）和磷酸盐（PO）等理化参数进行了测试，并将获得的数据与印度标准局（BIS）的标准进行了比较。在当前工作中，对使用SP种子处理（混凝）前后洗衣机排放水的水质的物理和化学参数进行了检测。测试程序采用烧杯试验，混凝剂质量为1000mg/L，在150rpm下快速搅拌5分钟，在30rpm下缓慢搅拌25分钟，沉降时间为1小时。报告了使用SP种子的混凝结果，其中去除浊度和PO的效率分别确定为81.54%和41.45%。通过傅里叶变换红外（FT-IR）光谱对SP种子中各种官能团的存在情况进行了评估。还对该物种种子提取物的植物化学成分进行了定性鉴定。实验结果强烈突出了SP种子从废水中去除浊度和PO的能力。
