Case study of using MI 2220-13 method for measuring wastewater flow rate in the feed channels of the aeration tanks at the Municipal Wastewater Treatment Facilities

Summary

Case study of using MI 2220-13 «Method of measuring in gravity water pipelines by the filling level with preliminary calibration of the measuring section» for measuring wastewater flow rate in the feed channels of the aeration tanks at the Municipal Wastewater Treatment Facilities of the Urban District of Samara is considered. The sequence of steps and operations of calibrating and finding the dependence of the flow rate on the measured level in the feed channel of the aeration tank is presented. The advantages of using this method lie in the possibility of determining the water flow rate from the measured level value using relatively simple and inexpensive level sensors. This approach is actively used by engineering companies while designing, including treatment facilities; however, at the stage of commissioning, the organizations responsible for commissioning often experience problems with setting up and debugging the operation of such flow meters.
