Abstract:
A submersible recording respirometer includes an oxygen analyzer which measures the concentration of oxygen absorbed by a wastewater sample contained in an aeration chamber. The aeration chamber forms part of a housing which is submerged in the main body of wastewater and the aeration chamber is periodically drained, washed with fresh water and refilled with another wastewater sample. This cycle is accomplished automatically under the direction of a microprocessor-based control circuit which generates signals to a chart recorder that provides a hard copy of the measurement results.
