Document Description
This project will measure PM2.5 and PM10 across the spray drift plume from two separate power plant cooling towers; one that utilizes fresh water and one that utilizes brackish water. These measurements will be used to develop and validate a model that power plant operators can use to minimize the PM2.5 and PM10 effects of brackish water use in cooling towers. There will also be testing of the equipment at an existing cooling tower at UC Davis campus. This project will measure the droplet size distribution, dried aerosol size distribution, PM2.5 mass, PM10 mass, and PM2.5 and PM10 aerosol composition in horizontal and vertical transects across the spray drift plume from two power plant cooling towers that use fresh water and brackish water. These measurements will be used to develop and validate a model of power plant PM2.5 and PM10 emissions as a function of atmospheric conditions, brackish water solids concentration, and operating characteristics of the cooling tower. The end result will be a model that power plant operators can use to minimize the PM2.5 and PM10 effects of brackish water use in cooling towers.
