The present study deals with the assessment of different physicochemical parameters (pH, electrical conductivity (E.C.), turbidity, total dissolved solids (TDS), and dissolved oxygen) in different surface water such as pond, river, and canal water in four different seasons, viz. March, June, September, and December 2023. The research endeavors to assess the impact of a cationic polyelectrolyte, specifically poly(diallyl dimethyl ammonium chloride) (PDADMAC), utilized as a coagulation aid in conjunction with lime for water treatment. Employing a conventional jar test apparatus, turbidity removal from diverse water samples is examined. Furthermore, the samples undergo characterization utilizing X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. The study also conducts correlation analyses on various parameters such as electrical conductivity (EC), pH, total dissolved solids (TDS), turbidity of raw water, polyelectrolyte dosage, and percentage of turbidity removal across different water sources. Utilizing the Statistical Package for Social Science (SPSS) software, these analyses aim to establish robust relationships among initial turbidity, temperature, percentage of turbidity removal, dosage of coagulant aid, electrical conductivity, and total dissolved solids (TDS) in pond water, river water, and canal water. A strong positive correlation could be found between the percentage of turbidity removal and the value of initial turbidity of all surface water. However, a negative correlation could be observed between the polyelectrolyte dosage and raw water's turbidity. By elucidating these correlations, the study contributes to a deeper understanding of the effectiveness of PDADMAC and lime in water treatment processes across diverse environmental conditions. This research enhances our comprehension of surface water treatment methodologies and provides valuable insights for optimizing water treatment strategies to address the challenges posed by varying water sources and seasonal fluctuations.
本研究评估了不同地表水中的不同物理化学参数（pH 值、电导率（E.C.）、浊度、总溶解固体（TDS）和溶解氧），这些水包括池塘水、河水和运河水，分别采集于 2023 年 3 月、6 月、9 月和 12 月四个不同的季节。该研究旨在评估一种阳离子型聚电解质（聚二烯丙基二甲基氯化铵（PDADMAC））作为助凝剂与石灰结合在水处理中的应用效果。使用常规的搅拌试验装置，考察了不同水样的浊度去除情况。此外，还采用 X 射线衍射（XRD）和扫描电子显微镜（SEM）技术对样品进行了表征。研究还对不同水源的电导率（EC）、pH 值、总溶解固体（TDS）、原水浊度、聚电解质用量和浊度去除率等参数进行了相关性分析。利用社会科学统计软件包（SPSS）进行这些分析，旨在建立池塘水、河水和运河水中初始浊度、温度、浊度去除率、助凝剂用量、电导率和总溶解固体（TDS）之间的关系。可以发现所有地表水的浊度去除率与初始浊度值之间存在很强的正相关关系。然而，聚电解质用量与原水浊度之间存在负相关关系。通过阐明这些相关性，本研究有助于深入了解 PDADMAC 和石灰在不同环境条件下的水处理效果。这项研究提高了我们对地表水的处理方法的理解，并为优化水处理策略提供了有价值的见解，以应对不同水源和季节性波动带来的挑战。
