COD can test wastewater that is too toxic for the BOD test. Can I use my COD results to predict my BOD? Sample 1: COD = 2,150 mg/L BOD = 1,100 mg/L Sample 2: COD = 1,990 mg/L BOD = 1,050 mg/L COD ÷ BOD = 1,990 ÷ 1,050 = 1.89 Sample 3: COD = […]

The ratio within the chemical oxygen demand (COD) and the biological oxygen demand over 5 days (BOD5) indicates the level of biodegradability of a sample. A low ratio COD/BOD5 (less than 2.0 or 2.5) indicates a high biodegradability, what means that it can be treated easily by a biological treatment. What is ratio between BOD […]

If the BOD/COD ratio for untreated wastewater is 0.5 or greater, the waste is considered to be easily treatable by biological means. If the ratio is below about 0.3, either the waste may have some toxic components or acclimated microoorganisms may be required in its stabilization. What is the ratio of BOD to COD for […]

indicator ferroin. Detailed Solution The excess potassium dichromate is titrated with ferrous ammonium sulphate (FAS) until all of the excess oxidizing agent has been reduced to Cr3+. The oxidation-reduction indicator ferroin is also added during this titration as it changes its color from red to pale blue when oxidized. Which indicator is used when the […]

It is used to indicate organic matter contamination and it helps in knowing overall organic load to the receiving body. There are two methods for COD determination. The first method: open reflux method is suitable for a wide range of wastes where large volume of sample is required (for samples with COD= 50 mg O2/L). […]

Using this conversion, the number 25, for example, would have a BCD number of 0010 0101 or 00100101. However, in binary, 25 is represented as 11001. How to convert BCD to decimal. Decimal BCD 6 0110 7 0111 8 1000 9 1001 How do you write BCD code? In BCD code, each digit of the […]

Sources: COD increases as the concentration of organic material increases. It also increases if inorganic compounds susceptible to oxidation by the oxidant (typically dichromate) are present. Water with high COD typically contains high levels of decaying plant matter, human waste, or industrial effluent. What causes high BOD and COD? I think that the main causes […]

Chemical Oxygen Demand. COD is defined as the amount of oxygen equivalents consumed in the chemical oxidation of organic matter by strong oxidant (e.g., potassium dichromate). What is COD in chemistry class 11? In environmental chemistry, the chemical oxygen demand (COD) test is commonly used to indirectly measure the amount of organic compounds in water. […]

Chemical oxygen demand (COD) is widely used as an organic pollution indicator in wastewater treatment plants. Large amounts of organic matter are removed during treatment processes to meet environmental standards, and consequently, substantial greenhouse gases (GHGs) such as methane (CH4) are released. What does a high COD indicate? The higher the COD value, the more […]

COD is “all those diseases, morbid conditions or injuries which either resulted in or contributed to death and the circumstances of the accident or violence which produced such injuries.”1 Statistics on COD facilitates informed policymaking. Does Cod mean cause of death? Medical certification of cause of death (COD) | World Health Organization International Form of […]

cash on delivery. cash on delivery: a system in which you pay for goods that you have ordered when they are delivered to you. Whats does COD mean? cash on deliverycash on delivery, collect on delivery. How does COD work? COD is used by senders who want to collect payment for merchandise and/or postage and […]

COD is an indicative measure of the amount of oxygen that can be consumed by reactions in a measured solution. It is commonly expressed in mass of oxygen consumed over volume of solution, which in SI units is milligrams per liter (mg/L). What is the unit of BOD and COD? BOD measures the amount of […]

HCl and HNO3 are not used in the titration of Mohr’s salt in place of sulfuric acid because: HCl is a mild reducing agent and it reacts with some of the indicator that is KMnO4 solution so the final value of the indicator used come to be more than the actual value disturbing the experiment. […]

Quality and Characteristics of Sewage MCQ Question 4 (i) The COD (Chemical oxygen demand) test is used to measure the content of organic matter of waste water, both biodegradable and non-biodegradble. What COD means? 1.1 Chemical Oxygen Demand. COD is an indicative measurement of the amount of oxygen that can be consumed by reactions in […]

BOD (or COD) load: Units: kg/day This is simply done by multiplying the BOD in mg/l by the daily effluent volume in cubic metres (m3) and dividing the product by 1000. How to convert COD mg l to kg day? Please provide values below to convert milligram/liter [mg/L] to kilogram/liter [kg/L], or vice versa.Milligram/liter to […]

COD and BOD tests are important because they help in the determination of the amount of waste in wastewater. This is important because the organic content in wastewater needs to be reduced before the wastewater is discharged. Why is it important to determine COD in wastewater treatment? In wastewater treatment, the Chemical Oxygen Demand (COD) […]

The main reason for using the blank sample is to control the volume of organic material in the sample. COD was carried out to measure the oxygen demand of organic compounds in a sample of water, and we have to ensure there were no accidentally outside organic materials added to the sample to be measured. […]

Divide the COD concentration by the BOD concentration for each sample and average the results. Can I use my COD results to predict my BOD? Sample 1: COD = 2,150 mg/L BOD = 1,100 mg/L Sample 3: COD = 1,850 mg/L BOD = 997 mg/L COD ÷ BOD = 1,850 ÷ 997 = 1.86 (1.95 […]
