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 […]

Do Pea Plants Need Compost?
Pea plants grow and produce in less than fertile soil. They prefer soil rich in organic material like compost and well-rotted manure. What is the best compost for peas? Many soils, from sandy to heavy clay, are good for peas as long as you have well-drained soil. Peas grow best in soil with a pH […]
What Causes High Cod And Bod In Wastewater?
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 […]
When The Ratio Of Bod To Cod Is 0.2 Biological Wastewater Treatment Is Not Recommended?
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 […]
What Is Ratio 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 […]
Can You Calculate Cod From Bod?
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 = […]
How Much Does Cod Delivery Cost?
Rates and prices. The sender must pay the COD fee of $7.25 plus shipping fees (you can choose to recover your shipping costs in your COD amount). How much is a COD charge? For Express Mail COD shipments valued at $100 or less, the COD fee is based on the amount to be collected.Collect on […]
What Is The Difference Between Cod And Prepaid?
Prepaid orders get processed faster as they do not require any verification. Most ecommerce companies nowadays call customers or send them SMS for confirming genuine COD orders. This causes delays in processing a COD order and leads to late shipments, besides increasing costs. What is Prepaid COD? Reach unresponsive customers In conclusion, PrePay CoD is […]
Can A Fig Tree Have Leaves Without Fruit?
Until the plant becomes mature and slows down in the production of leaves and shoots, it will produce few to no fruit. It may take a year or two more for your tree to slowly and gradually switch from producing mostly leaves and shoots to producing and maturing some fruit. Why would a fig tree […]
What Turns A Fig Flower Into A Gall?
As they oviposit, wasps also inject chemicals that transform individual flower ovaries into galls that will feed and house wasp offspring. For fig tree–fig wasp mutualisms to persist, the trees must set seed; therefore, the wasps have both to pollinate and to fail to gall all flower ovaries. What is a gall flower? Galls are […]

Can I cancel an order before it is delivered? Time is of the essence If the retailer does not deliver by then, you’ll be legally entitled […]
Are Peas Heavy Feeders?
Peas are “heavy feeders” while they are growing, so the soil should be very fertile. They return nutrients to the soil through nitrogen fixation as they mature. What vegetables are considered heavy feeders? Heavy-feeders are plants that require a lot of mineral nutrients to thrive. Examples include tomatoes, cabbage, broccoli, sunflowers, and onions. Light-feeders are […]
How Can Cod And Bod Be Used To Assess Water Quality?
Like COD, biochemical oxygen demand (BOD) measurement can be used to estimate the amount of pollution in a water sample. COD describes the amount of oxygen required to chemically break down pollutants, while BOD indicates the amount of oxygen required to breakdown organic pollutants biologically with microorganisms. How are BOD and COD used to tell […]
What Does A Wild Fig Look Like?

How is COD reduction calculated? The COD removal efficiency can be computed using ((Cin-Ceff)/Cin)*100) and expressed in %. What is the formula to calculate […]
Is Sugar Added To Dried Figs?
A: The sweetness in dates and dried figs is all-natural, it does not come from added sugars. These fruits have low water content which makes the naturally occurring sugars more concentrated.
