Lecture
This lecture covers the mechanical treatment processes in wastewater treatment, including thickening, settling tanks, sludge treatment, and biogas production. It also discusses the objectives, efficiency, and challenges of mechanical treatment, such as sand removal, organic matter processing, and screening technologies. The instructor explains the importance of proper sizing approaches, treatment goals, and the overall processing chain. Additionally, the lecture delves into the environmental impact of mechanical treatment, bacterial growth, and the presence of heavy metals in wastewater. Practical exercises on reprocessing screening waste and cost calculations are included to enhance understanding of the concepts.
