chemical oxygen demand lab report
The more food that is present in the water the more DO will be used up by the bacteria and the greater the BOD reading will be. The minimum volume does not allow for re-runs or QC specific Duplicate MS MSD analysis.
Chemical Oxygen Demand
Introduction The Chemical Oxygen Demand or COD is a measurement of the amount of material that can be oxidized combined with oxygen in the presence of a strong chemical oxidizing agent.
. LAB Report Traffic Volume Study uitm. The chemical oxygen demand COD is the amount of oxygen consumed to. The Biochemical Oxygen Demand or BOD is the amount of dissolved oxygen which is used up by these microorganisms and is roughly equivalent to the amount of food organic matter found in the wastewater.
A measure of organic materials concentration in the wastewater that can be oxidized by the bacteria and normally determined on the 5th day at 20C through the amount of oxygen consumed. Abbreviations DW Drinking Water NP Non Potable includes wastewater surface water etc HW Hazardous Waste 02. Three glass quarts amber for organics are required for MSMSD analysis.
Lakes and rivers making COD a useful measure of water quality. Additionally other chemicals and inorganic substances in the water can be oxidized by dichromate. Is an important rapidly measured variable for the approximate determination of the.
Most applications of COD determine the amount of organic pollutants found in surface water eg. Water Reticulation Design Project Outline. The COD test is more robust than BOD because not all organic matter is readily oxidized by bacteria.
COD is an important rapidly measured variable for the approximate. The chemical oxygen demand COD is the amount of oxygen consumed to completely chemically oxidize the organic water constituents to inorganic end products. Chemical Oxygen Demand Dissolved.

Chemical Oxygen Demand Lab Report Satisfactory Essays 783 Words 4 Pages Open Document Essay Sample Check Writing Quality Chemical Oxygen Demand COD is a measure of the capacity of water to consume oxygen during the chemical decomposition of the organic matter and oxidation of inorganic chemicals such as ammonia and nitrite. In those cases the EPA may allow the quicker COD test to be substituted for the 5-day-long BOD test 40 CFR 133104 b. LAB REPORT ANALYSIS FOR WATER AND WASTEWATER EVT525.
To better understand the influence of these process variables on the COD degradations experiments need to be conducted with various ranges of process variables. Lab Report 3 Chemical Oxygen Demand COD and Biological Oxygen Demand BOD Activity 5 and Activity 6 ENV 3001C Course Number002 14859 Environmental Science and Engineering Professor. These consequences can be analyzed through the help of the chemical oxygen demand lab that offers a guide on the quality of water discharged.
Chemical oxygen demand COD. For instance BOD may typically be 60 lower than COD results. Up to 24 cash back The chemical oxygen demand COD test is commonly used to indirectly measure the amount of organic compounds in water.
Chemical Oxygen Demand degradation depends on the process variables like initial pH inoculum concentration IC mixing intensity and temperature. WATER RESOURCE TECHNOLOGY NAME NORSHAFIQA BINTI S SHAM MATRIX NUMBER 2021853504 TOPIC CHEMICAL OXYGEN DEMANDCOD DATE OF SUBMUSSION 25 JUNE 2022 LECTURERS NAME DR NIK AZLIN NIK ARIFFIN OBJECTIVE The objective of this experiment was to evaluate the. Completely chemically oxidize the organic water constituents to inorganic end products.
In this study the procedure referred is APHA-5210 B. 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. The COD hold time is also much more forgiving at 28 days compared to 24 hours.
