Turbidity is a characteristic impurity of groundwater in Pakistan. Turbid water is not suitable for drinking purposes. The main objective of this study is to reduce water turbidity using natural coagulant, extracted from pine cones. The coagulation activity of coagulant is tested using synthetic turbid water. Coagulant activity is affected by various factors such as coagulant dose, water turbidity, pH, extract density and settling time. The optimum coagulant dose and water turbidities are fixed; 0.5 ml/L, 67, and 75 NTU, respectively. The highest coagulation activities are observed at pH values 2 and 12. Further, coagulation activity of pine cone extract is maximized to 82% when its density is 1.8 g/cm. Moreover, most of the coagulation activity takes place in the first hour. The results recommend the potential use of pine cone extract for turbid water purification.
浊度是巴基斯坦地下水的一种特征性杂质。浑浊的水不适合饮用。本研究的主要目的是使用从松果中提取的天然混凝剂降低水的浊度。使用合成浊水测试混凝剂的混凝活性。混凝活性受多种因素影响，如混凝剂剂量、水的浊度、pH值、提取物密度和沉降时间。确定了最佳混凝剂剂量和水的浊度，分别为0.5毫升/升、67和75 NTU。在pH值为2和12时观察到最高的混凝活性。此外，当松果提取物的密度为1.8克/立方厘米时，其混凝活性最大可达82%。而且，大部分混凝活性在第一个小时内发生。结果表明松果提取物在净化浊水方面具有潜在用途。
