Theoretical carbonaceous oxygen demand

WebbFinal answer. Step 1/3. To calculate the theoretical carbonaceous oxygen demand (Th-COD) for water containing 50 mg/L of acetic acid, we can use the balanced reaction provided: C H 3 C O O H + 2 O 2 → 2 C O 2 + 2 H 2 O. WebbBiochemical oxygen demand (BOD) is a measure of the dissolved oxygen consumed by microorganisms during the oxidation of reduced substances in waters and wastes. Typical sources of BOD are readily biodegradable organic carbon (carbonaceous, CBOD) and ammonia (nitrogenous, NBOD).

The COD actually represents the ultimate BOD (BOD u) or the amount of dissolved oxygen to completely oxidize the organic matter in a sample, and the COD will always exceed BOD 5. The BOD 5 concentration typically is around 65 percent of the COD concentration. reading tutors near brooklyn park https://digitalpipeline.net
