Theoretical classes: Origin of wastewater. Characterization of wastewater. Emission standards for wastewater. Analysis and selection of wastewater flow and load elements. Selection of unit wastewater treatment processes, alternative process technologies for wastewater treatment. Conceptual solution of the purification process and wastewater treatment plant. Designing stages of wastewater treatment process: mechanical purification processes, chemical purification processes, biological purification (processes with suspended microflora, processes with immobilized microflora, anaerobic processes); improved purification processes; disinfection. Waste streams of the wastewater treatment processes, their treatment and disposal. Aspects of plant operation (process control and management; smell control; energy efficiency). Practical classes: Demonstration of the design process: conceptualization of wastewater treatment processes; development of the conceptual solution of the process line (technology) for wastewater treatment and wastewater treatment plants; development of a technological project for a wastewater treatment plant.
