Nutrition. Cod is a low-fat source of protein, making it an excellent choice for people who would like to reduce their fat intake and improve their heart health. Cod also contains a significant amount of iodine, which is an important mineral for thyroid function.
What are the advantages of COD and BOD?
Chemical Oxygen Demand (COD) v/s Biological Oxygen Demand (BOD)
| BOD | COD |
|---|---|
| BOD is used to oxidize the natural organic matter and organic waste in the water | COD is capable of degrading the industrial sewage. COD does not measure the amount of oxygen consumed by acetates present in the water sample |
What are the 2 advantages and disadvantages of COD test over BOD?
COD is normally higher than BOD because more organic compounds can be chemically oxidised than biologically oxidised. This includes chemicals toxic to biological life, which can make COD tests very useful when testing industrial sewage as they will not be captured by BOD testing.
What is the importance of COD?
COD is a water quality measure used not only to determine the amount of biologically active substances such as bacteria but also biologically inactive organic matter in water [8]. It is an important and rapidly measured variable for characterizing water bodies, sewage, industrial wastes, and treatment plant effluents.
What are the disadvantages of COD?
Disadvantages of Cash on Delivery (COD) mode of payment
The seller at this point will have already incurred transportation costs which accumulate to a loss for the e-commerce business. 2. The business representatives will be handling a lot of cash through the COD system unlike in the use of credit cards.
What are the advantages of BOD?
The main advantages of this method compared to the dilution method are: simplicity: no dilution of sample required, no seeding, no blank sample. direct reading of BOD value. continuous display of BOD value at the current incubation time.
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 a measured solution. It is an indicator of the contents of reducing substances in the water, which are organic, nitrite, sulfide, ferrous salts, etc., and the organic is dominant.
Which one is better BOD or COD?
COD is always higher than BOD because chemical oxidation is easier than biological oxidation.
What are the disadvantages of cash on delivery?
One of the challenges with cash on delivery is that it makes the seller vulnerable to losses when the customer returns the product without paying for it. You spend all the money to deliver the product, but ultimately it got replaced. This adds to your revenue loss.
Why is COD higher than BOD?
The COD test uses a chemical (potassium dichromate in a 50% sulfuric acid solution) that “oxidizes” both organic (predominate) and inorganic substances in a wastewater sample, which results in a higher COD concentration than BOD concentration for the same wastewater sample since only organic compounds are consumed
Why COD is important in water treatment?
In wastewater treatment, the Chemical Oxygen Demand (COD) is an important measurement for the amount of oxygen that is required to break down pollutants (organic substances) in water. The chemical oxygen demand can be measured using different methods, direct or indirect.
What are the sources of COD?
Sources of COD in stormwater are varied. However, soluble organic compounds are most likely to contribute to escalated COD concentrations. Residual food waste from bottles and cans, antifreeze, emulsified oils are all high in COD and are common sources of COD for industrial stormwater.
Is COD risky?
With COD, there’s also a higher risk of delivery refusal. This can be especially disastrous when suppliers are transporting perishable goods. When this happens, suppliers lose profit on returned or spoiled goods and may have to pay shipping return fees.
What are the advantages of credit sales?
Advantages of Credit Sales
When a company sells on credit, it attracts new customers who would otherwise not buy from the company. This is mostly true for companies that sell expensive items. Credit sales allow customers, especially business customers, to generate cash on the commodity before paying the seller.
How does COD work?
The COD Methodology
Delivery agents collect the invoice amount of a consignment from its consignee in the form of cash at the time of delivery. The collected cash is then deposited at the local office of the eCommerce company that made the sale. In this method of payment, both the buyer and seller are satisfied.
What is COD & BOD in water?
The biochemical oxygen demand (BOD) represents the amount of dissolved oxygen (DO) consumed by biological organisms when they decompose organic matter in water. The chemical oxygen demand (COD) is the amount of oxygen consumed when the water sample is chemically oxidised.
What is BOD value of water?
BOD values range widely; generally, pristine waters have a value below 1 mg l−1, moderately polluted waters 2–8 mg l−1, and treated municipal sewage 20 mg l−1.
How is BOD and COD measured?
Testing for BOD involves incubating a sealed water sample at 20C for five days, followed by measuring the difference in oxygen content before and after incubation. COD measures how much DO is consumed by the oxidation of organic matter and inorganic compounds such as ammonia or nitrite under controlled conditions.
How COD is calculated?
There is a formula for calculating COD. Consider the formula for COD calculation: (a – b) X C X 8,000 / the volume of the sample in mL. Let “a” represent the titrant used for your sample expressed in mL. Let “b” represent the titrant used for your blank sample in mL.
What if COD is high in water?
When the COD levels are higher, there is a greater demand for oxygen. This means that there is likely more oxidizable organic material in water with high COD levels. This also means that there are reduced Dissolved Oxygen (DO) concentrations in wastewater with high COD levels.
What should be the COD of drinking water?
According to standards of Central Pollution Control Board, permissible value of BOD is 30 mg/l and COD is 250 mg/l. Hope this helps, it mentions standards for India relating to different uses.
