Assessment of Poly (diallyl dimethyl ammonium chloride) and Lime for Surface Water Treatment (Pond, River, and Canal water): Seasonal Variations and Correlation Analyses

Abstract

This study investigates the basic characteristics of various surface water sources, including pond water, river water, and canal water, across four distinct seasons. The research endeavours 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 purposes. 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. 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 not only enhances our comprehension of surface water treatment methodologies but also provides valuable insights for optimizing water treatment strategies to address the challenges posed by varying water sources and seasonal fluctuations.
