The Evaluation of Sewage Temperature and Flow Rate for Estimating Sewage Temperature and Flow Rate in Sewer Line

Abstract

In order to treat sewage, it is required to estimate sewage temperature and sewage flow rate near domestic and industrial the buildings. In this study, we measured the sewage temperature and flow rate in a sewer line to characterize the characteristics of sewage. 1) We measured the sewage temperature and flow rate at 17 at locations in t three different sewage-treatment in Osaka City. 2) In catchment areas corresponding to large housing ratios, we observed that the trend of the hourly sewage flow rate and the hourly ratio of house water consumption are similar. 3) We analyzed the correlation of the monthly average sewage temperature and air temperature. As a result, the correlation of 0.9 determined from the study provided a highly accurate regression equation. 4) With respect to the intended purpose of a given building (domestic od industrial), the characteristics of sewage flow rate differ between weekdays and holidays.
