Your company just retooled/replaced its equipment, and management wants to know if the existing PM control system can still be used. Using the information about the control equipment and the characteristics of the PM in your new effluent stream, answer the following: a) Calculate and report the overall collection efficiency of the following PM control configuration using the included information about the PM in the effluent, and the information about efficiency of each stage of your control equipment. b) Can the existing system be used for the new process? Do you think the new effluent stream will overwhelm any portion of your control system? c) Given the information below, and the results of Part (a), will your effluent meet the requirements for the 24-hour NAAQS for PM10 and PM2.5 (after it has been treated by your control equipment)? If not, what would you suggest adding to the system to reach attainment? d) Why is it important to consider the entire size range of PM emissions when designing control strategies? NOTE: All collection efficiency curves for this problem are included in a larger format at the end of this document (last two pages)
