How do you calculate sludge production
WebPrimary sludge is produced if primary clarifiers precede the oxidation ditch. Sludge production for the oxidation ditch process ranges from 0.2 to 0.85 kg TSS per kg (0.2 to 0.85 lb. TSS per lb). BOD applied (Sherwood Logan and Associates, 1999). Typical sludge production is 0.65 kg TSS per kg of BOD (0.65 lb TSS per lb. of BOD). This is less than Webper day and the pounds of activated sludge or secondary effluent solids discharged per day (Equation I.6). (I.6) The MCRT of an activated sludge process can be calculated by dividing the pounds of suspended solids or MLSS in the activated sludge process by the pounds of suspended solids leaving the activated sludge process (Equation I.7).The MCRT

WebParticulate COD of sludge is made up of the terms involved in the following sum: Particulate COD = XI + XP + XS + XBH + XBA. Omitting the two smaller fractions, XS and XBA, the … 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.

WebCalculation : The daily sludge mass produced = ( 100,000 ) ( 0.080 ) = 8,000 kg dry SS / day. Since 97 % MC is 3 % SC or approximately 30 kg dry SS / m 3 sludge, the daily volume produced is 8,000 / 30 = 267 m 3 . What is viscosity of sludge?
