A. Cakici et Jd. Boyle, SIMULTANEOUS ESTIMATION OF OXYGEN-UPTAKE RATE AND RE-AERATION RATE INAN INDUSTRIAL WASTE-WATER TREATMENT PROCESS, Process safety and environmental protection, 73(B2), 1995, pp. 132-136
This paper presents estimations of both re-aeration rate coefficient K
(1)a and oxygen uptake rate (OUR) obtained from a well mixed simulated
aerated sludge reactor in a pilot plant. Estimates of OUR, which is a
significant indicator of the biological activity in the reactor, and
K(1)a were obtained while controlling the concentration of dissolved o
xygen in the reactor. The control and parameter estimation algorithms
were developed using a commercially available process control package.
Estimates for both OUR and K(1)a are reliable and do not degrade with
time.
