Abstract
A probabilistic method of sizing a multi-stage rotating biological contactor (RBC) for carbon removal is presented. The optimal relationship between the soluble biochemical oxygen demand (SBOD) concentrations of adjacent RBC stages is incorporated into a probabilistic method of assigning per-stage active disc areas. Bivariate lognormal and shifted lognormal distributions are considered as models for the input random variables. The effluent SBOD probability density function is obtained according to the method of transformation of random variables. The probability of the final stage SBOD exceeding a specified concentration is evaluated by numerical integration of a risk function. An illustrative example is presented.
