ABSTRACT
In Examples 1 and 2, the sludge pumped to the digester was expressed as lbslday. Many times, however, sludge pumped to the digester is expnssed as gpd or gpm. When this is the case, convert the gpd or gpm pumping rate to lbslday* and continue as in Examples 1 and 2. You can make the gpd to lbslday conversion a separate calculation, or you can incorporate it into the numerator of the equation as shown in Example 3.
