How do you calculate sludge production
WebSince precise calculations of biosolids production is complex, we use the amount of BOD removed to get an estimation. BOD removed, lb/day = BOD removed, mg/L x Flow, MGD x 8.34 lb/gal. Example: The 1.25 MGD influent to the secondary clarifier has a BOD concentration of 182 mg/L. The secondary effluent contains 21 mg/L BOD. WebThis means you will need to add 121,176 gallons of seed material to the new digester to acheive normal operation. Organic Loading Rate. Given the volumes of feed sludge, sludge concentrations, volatile solids, and the volume of the digester, you can calculate the organic loading rate of the digester in pounds per day per cubic foot.
