WebDuring the treatment facility design process, possible impacts of design flows and loadings on each upstream and downstream unit process should be considered. Definitions . Existing flow data for critical low and peak wet weather events are used to estimate the following flow conditions critical to the design of wastewater treatment plants . Web1.2.4 PEAK DIURNAL FLOWRATE. The normal daily range of the rate of flow, or the diurnal pattern, is from approximately 40 percent to 250 percent of the average daily flow. The peak daily or diurnal flowrate is an important factor in sewer design, especially when minimum velocities are to be provided on a daily basis. The peak diurnal flowrate WebApr 26, 2012 · Abstract. The peaking factor (PF) is the ratio of the maximum flow to the average daily flow in a water system The PF concept has been used in both the drinking water and wastewater industries for nearly 100 years. Since there is some variability in the magnitudes of the maximum and the average daily flow, both can be treated as random ... basel 1 rbi
