Analysis of the age of water in the pressure sewer network
Zuzaňák, René ; Nevrlý, Robert (referee) ; Ručka, Jan (advisor)
The thesis deals with the age of wastewater in the pressure sewer network in the village of Horní Ředice, Pardubice district. In the introductory part of the thesis the current state of the problem is presented. The second part focuses on general principles for design and operation of pressure sewers. In the practical part, the area of interest was first characterized and the sewerage system in the municipality was described. A quasidynamic hydraulic model of the entire pressure sewer network was developed to determine the age values of the wastewater in the pressure sewer network. The operating conditions were projected in the simulation model of EPANET 2.2. Pressure ratios, wastewater age, flow velocities and flows in the pressure sewer network were considered in the processing of the hydraulic analysis results. Based on the results of the hydraulic analysis, measures to improve the conditions in the pressure sewer network were proposed.
