Da. Sanders et al., COMPUTER MODELING OF SINGLE SLUDGE SYSTEMS FOR THE COMPUTER-AIDED-DESIGN AND CONTROL OF ACTIVATED-SLUDGE PROCESSES, Microprocessing and microprogramming, 40(10-12), 1994, pp. 867-870
The initial work for the creation of a new automatic CAD system for ad
vanced effluent treatment processes is presented. The creation of a co
mputer model for a completely mixed aerator is described. The computer
modal consisted of two interacting non-linear differential equations,
which were linearised to give an approximate computer modal. Optimal
control theory was applied to the design of a controller for this syst
em and a series of experiments examined the system performance using b
oth the new computer model and the new controller.
