I have the influent and effluent COD concentrations (mg l-1), HRT, and OLR for my batch bioreactor system. The COD removal efficiency can be computed using ((Cin-Ceff)/Cin)*100) and expressed in %. 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 […]

Most commonly, a 0.25 N solution of potassium dichromate is used for COD determination, although for samples with COD below 50 mg/L, a lower concentration of potassium dichromate is preferred. Why potassium dichromate is used in COD? Currently, most COD tests use potassium dichromate as the oxidant. Potassium dichromate is a hexavalent chromium salt that […]

© Activision. In Call of Duty: Warzone you have 100 HP by default. This is shown by the white bar in the bottom left corner of your screen. Your health regenerates quickly if you aren’t shot at for a few seconds, but you can also use stims to boost it back to full immediately while […]

The Common Origination and Disbursement (COD) system is designed to support origination, disbursement, and reporting for Direct Loan, Federal Pell Grant, and the Teacher Education Assistance for College and Higher Education (TEACH) Grant programs. What does Cod stand for in financial aid? Common Origination and DisbursementCOD Online. Welcome to the U.S. Department of Education’s Common […]

The Full form of COD is Cash on delivery or Collect on delivery. COD is a monetary/financial transaction where the payment of products or services received by mail order is done at the time of actual delivery by the customer rather than in advance. What is the full form of COD in geography? Cash On […]

Capacity on demand. Capacity on demand (COD) is a purchasing option that allows companies to receive equipment with more computer processing, storage or other capacity than the company needs at the time of purchase, and have that extra capacity remain unused and unpaid for until the company actually requires it. What does COD mean in […]

COD = (C/FW)·(RMO)·32. Why COD is calculated? Chemical oxygen demand (COD) is used to determine the quantity of pollution in water after wastewater treatment. The higher value of chemical oxygen demand indicates the higher organic pollution in the water sample. Only chemically digest able matter can be determined by the COD test. How COD is […]

The TDS is the sum of all dissolved solids which included COD also. Thus TDS should be higher than COD. Sir, COD should include acid digestion of all the organics and inorganic compounds (Dissolved and suspended) in water or wastewater. Hence, COD should be greater that TDS. What is BOD COD and TDS? These parameters […]

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 […]

In anaerobic treatment, bacteria convert organic compounds (COD) to biogas in an environment without oxygen. Not only do the bacteria remove contaminating compounds from the effluent, thereby reducing discharge costs, they produce green energy at the same time. For what range of COD level anaerobic digestion is carried out? around 1500-2000 mg/LFor what range of […]

Method summary An aliquot of the sample is digested for two hours at 150°C in the presence of dichromate and sulfuric acid. The resulting solution is titrated to a colored endpoint with ferroin indicator or read on a spectrophotometer at an appropriate wavelength. How do you do the COD test? Test for Chemical Oxygen Demand: […]

7.1 Pipet a 50.0 mL aliquot of sample not to exceed 800 mg/L of COD into a 500 ml, flat bottom, Erlenmeyer flask. Add HgSO4 (6.4) in the ratio of 10 mg to 1 mg chloride, based upon the mg of chloride in the sample aliquot and 5 mL of sulfuric acid (6.7). Swirl until […]

Chemical oxygen demand (COD) is used to determine the quantity of pollution in water after wastewater treatment. The higher value of chemical oxygen demand indicates the higher organic pollution in the water sample. Only chemically digest able matter can be determined by the COD test. What is the principle of chemical oxygen demand? The principle […]

In anaerobic treatment, bacteria convert organic compounds (COD) to biogas in an environment without oxygen. Not only do the bacteria remove contaminating compounds from the effluent, thereby reducing discharge costs, they produce green energy at the same time. What is the COD of methane? The COD of methane can be calculated using 1 g COD […]

The loading rate is the COD load divided by the reactor volume, but sometimes is referred as volumetric loading rate kg/m3*d. The formula is TCOD(kg/m3)*Q(m3/d)/V(m3)= TCOD load(kg/d)/V(m3)= result (kg/m3*d) Cite. Deleted profile. What is COD loading? BOD (or COD) load: Units: kg/day Biological wastewater treatment plants are designed and operated on the basis of the […]

Ferroin. Which of these is the used as the indicator when the titration is carried out to determine the amount of COD present in a sample. Explanation: Ferroin is the indicator used while titration is carried out to determine the COD present in a water sample. Which indicator is used in titration of COD test? […]

How to calculate the total organic loading rate (TOLR) in terms of chemical oxygen demand (COD)? [(COD mg/lit) x (Volume m3/ year) x (1000lit)]x 10–6 . How is organic loading rate calculated? Calculate the hydraulic loading rate with the formula: Hydraulic loading rate = Design flow (gal/day) / Area (feet ^2). Design flow is the […]

Biochemical oxygen demand (BOD) is the amount of oxygen it takes to degrade organic matter. Chemical oxygen demand (COD) is the amount of oxygen required to oxidize organic compounds (>500 milligrams per liter). Total suspended solids (TSS) is the total amount of suspended materials (>250 milligrams per liter). What is COD & BOD? Biochemical oxygen […]
