BOD stands for Biochemical Oxygen Demand is the amount of oxygen required for bacteria to decompose biodegradable organic matter at certain temperature for a specific period of time. Biochemical Oxygen Demand BOD The amount of oxygen required by the bacteria while stabilizing decomposable organic matter under aerobic conditions.
CEM NITTTR Lab Sample Number BH1. In this experiment we will try to find the temperature that organisms thrive best in on an organism dependent on oxygen and three types of water. Biochemical Oxygen Demand BOD generally represents how much oxygen is needed to break down organic matter in water.
It is used mainly in determination of pollution strength of water in terms of requirement of oxygen when this wastewater is discharged into water. This curve can then be used to determine the Ultimate BOD of the wastewater sample and the rate constant for its decay. Explain briefly the steps of COD measurement that you should follow during this experiment.
The chemical oxygen demand COD is the amount of oxygen consumed to completely chemically oxidize the organic water constituents to inorganic end products. Biochemical oxygen demand bod date of experiment. Sample must be delivered to the lab within 24 hours of collection Method Preparation of Dilution Water 1.

Demand BOD COD measures the amount of oxygen used to oxidize organics in wastewater to. BOD represents the amount of oxygen consumed by bacteria and other microbes while they decompose organic matter under aerobic oxygen is present conditions at a specified temperature. 10-20 liter carboy 6.
The purpose of this experiment is to perform a Biochemical Oxygen Demand test on primary clarifier effluent from a wastewater treatment plant to determine a BOD versus time curve. Contoh expriment BOD. Biological oxygen demand is affected by the same factors that affect dissolved oxygen.
Unfortunately the data obtained. By using BOD3 the time of experiment can be shorten and the effect of experiment almost the same with BOD 5. Similarly Chemical Oxygen Demand COD is the demand of oxygen required to reduce dichromate Cr 2 O 72 - Cr in 6 oxidation state to Cr 3.
Air pump with air stone 5. Temperature of water. Carefully fill a BOD bottle with sample water without making air bubbles.
The COD test is more robust than BOD because not all organic matter is readily oxidized by bacteria. Ec2206c4a group members 1. See Appendix A7-A Table 1 for information on the parameter code for biochemical oxygen demand that is used in the National Water.
