Biofilter plenum design calculations
WebThe plenum geometry features four runners equally spaced from the restrictor’s exit located at the bottom portion of the domed plenum. This plenum shape requires incoming air to make a 180 degree turn to enter the runners. 3.4 Plenum Design Parameters Based on design calculations, the output parameters are shown in table 3. WebJul 20, 2015 · EBCT simply refers to the amount of time (usually in seconds) that air must spend in contact with the media or the contact chamber inside the process vessel. With no real basis in science or technology, this rule-of-thumb design criteria has persisted in odor control processes due to its simplicity. EBCT is calculated without regard for the ...
