N2 - In this second part of the paper, optimization models for design of water treatment plants for turbidity removal are discussed. Application of the models is illustrated with a case study. The results from the case study indicate cost differences of about 16-64%, solely due to change in the influent particle size distribution (PSD), with higher cost of treatment for the influents with relatively greater fraction of fine particles. The system configuration, level of treatment, and design and operating parameters are found to be different for each influent PSD. Use of other parameters like turbidity units, suspended solids and volume average diameter are unable to explain this variation. The influence of PSD on the total cost decreases with inflow. Integration of process optimization in system optimization is justified as the different design and operating parameters are selected under each level of treatment. The cost of sludge treatment accounts to about 30-50% of the total plant cost.
