Palm oil mill effluent has an average of BOD of 25,000 ppm. BOD and COD are the main parameters to be analyzed. Describe the differences between BOD (Biochemical oxygen demand) and COD (Chemical oxygen demand)?
Homework Answers
| BOD (Biochemical Oxygen Demand) | COD (Chemical Oxygen Demand) |
| It is the amount of dissolved oxygen needed for biochemical oxidation of organic matter, by microorganisms present in water sample. | It is the amount of Oxygen required for the oxidation of organic matter in water sample by a strong chemical oxidant, for example, KMnO4. |
| Time consuming, usually takes 5 days, and is carried out at 20°C. | Takes relatively shorter time than BOD test. |
| The test is affected by the type of microorganisms, pH, presence of toxin, etc. | Such unfavorable conditions do not affect COD test. |

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
