bod experiment lab report
Temperature of water DVTime of oxygen depletion By oxygen Indicator. Biochemical oxygen demand BOD Bacteria placed in contact with organic material will utilize.
Biological Oxygen Demand Lab Analysis And Background
Ratio of BOD to COD greater than or equal to 08 indicates that.
. The primary difference between BODn determination and other measurements such as pH conductivity oxygen COD nitrate etc is the fact that biological systems rather than chemical. A higher BOD indicates more oxygen is required signifying lower water quality. Group Lab Report 2 Measurements of BOD and COD By Team 1 ProfessorDr.
Keep the bottle in BOD incubator for 5days of incubation. Biochemical oxygen demand or BOD is a chemical procedure for determining the amount of dissolved oxygen needed by aerobic biological organisms in a body of water to break down. Biochemical Oxygen Demand BOD Show More.
1 Laboratory Report Experiment 6 Biochemical Oxygen Demand Group 1 Jonathan Damora Tuesday March 11 2014. It was carrying out to. Yeomin Yoon Group MembersRami Al Cheikh Arwa Alsaadi Larry Barrientos and Jacob Blackmon Date.
Because BOD changes with respect to time it is important to report at what time a BOD measurement was made. Up to 24 cash back BOD Lab Report IV. 2 Purpose The purpose of thisexperimentisto.
After incubation titrate 50 ml of sample water with 0025N Sodium thiosulphate to a pale yellow color. Aquatic life requires dissolved oxygen in the water therefore. Biochemical oxygen demand bod date of experiment.
The most common time interval for reporting BOD values is 5. 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 is a test which requires a sample to have its dissolved oxygen DO content measured be incubated under controlled conditions 20C for 5 days.
The determination of Biochemical Oxygen Demand BOD is used in studies to measure the self-purification capacity of streams as a means of checking on the quality of effluents discharged to stream waters. The preview shows page 2 - 3 out of 12 pages. 22 april 2020 group.
1 OBJECTIVE This experiment was conducted to measure the five day biochemical oxygen demand BOD5 of samples of raw wastewater. Up to 24 cash back The ratio of BOD to COD is useful to assess the amenability of waste for biological treatment. Environmental engineering laboratory ecw 568 open-ended lab report title of experiment.
Low BOD means less oxygen is being removed from the water so the water is usually more pure. The dissolved oxygen DO value for all samples were reduced after five days due to the microorganisms have uptake the oxygen in the samples. References for section 70 Five-d ay biochemical oxygen demand are located at the end of Chapter A7 in the Selected References and Documents section which begins on page REF-1.
