Practical methodology for predicting critical operating range of biological systems treating inhibitory substrates



Practical methodology for predicting critical operating range of biological systems treating inhibitory substrates



Journal Water Pollution Control Federation 60(1): 77-85



The critical specific growth rate, .mu.*, corresponding to a critical reactor substrate concentration, S, appears to have practical utility for plant operations and for grading various industrial wastes regarding their potential for causing operational problems. In the current work a test procedure has been modified and extended to substrates other than phenol. It is shown that the .mu.* values determined in batch growth studies for 2,4-dinitrophenol and orthochlorophenol predicted the wash-out point for continuous flow reactors which were fed these substrates. It was also found that changes in the numerical values of .mu.* induced by changes in operation of the continuous flow reactors were reflected in the .mu.0.5 values determined from the batch studies.
