Wastewater sludge generated in industrial and municipal processes presents a significant environmental challenge due to its high-water content. This work focuses on determining the different types of water binding in wastewater sludge samples using thermal analysis and the sludge settling by jar tests. The aim of the research is to identify modes of water binding in sludge and investigate effective methods for its removal. Thermal analysis, including techniques such as differential thermal analysis (DTA) and thermogravimetric analysis (TGA), allows for the determination of temperature ranges at which differently bound water is released from the sludge. Additionally, jar tests showed that cationic polymer additives as flocculants more effectively separate the waste sludge from water compared to anionic polymers. Findings of this research contribute to a better understanding of sludge drying and treatment processes, potentially leading to the development of more efficient and sustainable methods for handling wastewater sludge, thereby reducing environmental impact and processing costs.
