Abstract
A method for monitoring and regulating waste water treatment by anaerobic fermentation by measuring enzymatic activity or adenosine triphosphate (ATP) concentration. The method provides for earlier detection of abnormal fermentation conditions and allows adjustment of controllable variables prior to the appearance of abnormal effluents. Also described is an apparatus for controlling waste water treatment by a device which continuously measures the enzyme or ATP concentration in the treated water.
Claims2
A method of controlling waste water treatment by anaerobic fermentation, comprising:
- continuously measuring the enzyme activity in the water treated by the anaerobic fermentation;
- and
- controlling various fermentation conditions as occasion demands on the basis of the result of the measurement.
