A scheme to maximize reliability and to identify upsets caused by influent and process disturbances of the activated sludge treatment system with recycle is presented. Reliability is the probability that the effluent wastewater quality meets the maximum contamination standard for BOD5. The plant is assumed to operate under steady-state conditions. Since influent flow and substrate concentration have significant variation, they are introduced into the model as random variables. thus concerns about plant stability are addressed. Reliability is expressed as a function of return sludge concentration and recycle flow. Control charts are used to identify upsets caused by influent disturbance, combinations of flow and BOD5. and process disturbance, combinations of F/M (food to microorganism ratio) and MLSS (mixed liquor suspended solids). Recommendations to maximize reliability in the overall context of plant performance are presented and discussed. |
