Sludge blanket height (SBH) is an important parameter in the clarifier design, operation and control. Based on an overview
and classification of SBH algorithms, a modified SBH algorithm is proposed by incorporating a threshold concentration limit
into a relative concentration sharp change algorithm to eliminate the disturbance of compression interfaces on the correct
simulation of SBH. Pilot-scale test data are adopted to compare reliability of three SBH algorithms reported in literature
and the modified SBH algorithm developed in this paper. Calculated results demonstrate that the three SBH algorithms give
results with large deviation (> 50%) from measured SBH, especially under low solid flux conditions. The modified algorithm
is computationally efficient and reliable in matching the measured data. It is incorporated into a one-dimensional clarifier
model for stable simulation of pilot-scale experimental clarifier data and into dynamic simulation of a full-scale wastewater
treatment plant (WWTP) clarifier data.
