Abstract
The disclosure relates to obtaining dynamic wet pressure in a wastewater treatment plant. A difusser submerged in wastewater is connected to an air supply. This diffuser has an air flow regulator, a diffusion element to discharge the air into the wastewater, and a plenum situated between the element and the flow regulator. Pressure taps sense pressure in the pipe and the plenum. Manometers are used to determine hydrostatic head, pressure drop across the element, and pressure drop across the air flow regulator. Air flow regulator pressure drop and pressure/flow characteristics may be used, with other required information, to calculate dynamic wet pressure across the diffusion element.
