This research evaluates extracts from the bark of and as coagulating agents for removing turbidity in domestic wastewater, considering the coagulant dosage and pH of the wastewater. ANOVA was conducted to assess differences between the coagulants, dosages, and pH, with three pH levels (5, 8, and 9) and six dosages (7, 9, 11, 13, 15, and 17 mL per 1000 mL of wastewater) at a significance level of α = 0.05, and both the -value and effect size were evaluated. This study found that the mucilaginous compound from the bark of performed better in reducing turbidity levels, with an average reduction of 30.2 NTU (Nephelometric Turbidity Unit) ( [25.9 NTU; 34.5 NTU], α = 0.05) at a pH of 5, and an average initial NTU of 102.2. This represents an average reduction of 70.45%. The dosage factor did not show significant effects on turbidity reduction, which opens the possibility for further study to determine the optimal dosage of the best coagulant.
本研究评估了[两种植物名称未给出]树皮提取物作为生活污水浊度去除凝结剂的效果，同时考虑了凝结剂用量和废水的pH值。进行了方差分析以评估凝结剂、用量和pH值之间的差异，设置了三个pH水平（5、8和9）以及六个用量（每1000 mL废水7、9、11、13、15和17 mL），显著性水平α = 0.05，并对p值和效应大小进行了评估。本研究发现，[一种植物名称未给出]树皮中的黏液质化合物在降低浊度水平方面表现更好，在pH值为5时，平均降低30.2 NTU（浊度单位）（[25.9 NTU；34.5 NTU]，α = 0.05），初始平均NTU为102.2。这代表平均降低了70.45%。用量因素对浊度降低未显示出显著影响，这为进一步研究确定最佳凝结剂的最佳用量提供了可能性。
