difference between bod and cod

Biochemical Oxygen Demand BOD and CBOD. COD should always measure higher than TOC and then BOD.

BOD or CBOD COD TOC and Oil Grease.

. Answer 1 of 3. TOC or Total Organic Carbon is the measurement of organic carbons. What are the main differences of C-BOD vs.

Biochemical Oxygen Demand BOD is a way to measure organic pollution in water by looking at the rate at which micro-organisms in the water use up dissolved oxygen when they metabolize the. The fundamental distinction between BOD and COD is that BOD refers to the quantity of oxygen consumed by bacteria during the aerobic decomposition of organic matter whereas COD refers to the amount of oxygen necessary for the chemical oxidation of total organic matter in water. COD or Chemical Oxygen Demand is the total measurement of all chemicals in the water that can be oxidized.

Increased BOD conductivity decreased COD pH hardness alkalinity and significant release of SO 42- confirm the mineralization of the polluted water during this treatment process. TOC or Total Organic Carbon is the measurement of organic carbons. There is a strong correlation between COD and BOD however COD analysis is a much faster and more accurate method.

Een BOD and COD. The key difference between BOD and COD is that the BOD is the oxygen demand of microorganisms to oxidize organic matter in the water under aerobic conditions while the COD is the oxygen demand to oxidize all the pollutants in the water chemically. On the other hand Biological Oxygen Demand BOD and Chemical Oxygen Demand COD are both measures of the amount of oxygen required to biologically or chemically breakdown the pollutants within a known amount of water.

It is the amount of dissolved oxygen needed by bacteria in decomposing the organic waste presen. Quality of a given water sample depends on some variable factors. COD or Chemical Oxygen Demand is the total measurement of all chemicals in the water that can be oxidized.

N-BOD means Nitrogenous Biochemical Oxygen Demand BOD5 typically includes C-BOD and N-BOD unless one or the other is inhibited. There are two completely different tests-a C-BOD test and a BOD5 test. Biochemical oxygen demand BOD is the amount of oxygen required by the microorganisms to break down the organic materials whereas chemical oxygen demand COD is the amount of oxygen required to break down the organic material via oxidation.

Biochemical Oxygen Demand BOD is the measurement of the amount of oxygen consumed by aquatic microorganisms to decompose or to oxidize the organic matter. There are 4 common tests to determine organic pollution in wastewater. COD is the amount of oxygen required to chemically breakdown the pollutants whereas BOD is the amount of oxygen required to do this biologically through micro-organisms.

BOD- Biochemical Oxygen Demand is supposed to measure the amount of food or organic carbons that bacteria can oxidize. BOD- Biochemical Oxygen Demand is supposed to measure the amount of food or organic carbons that bacteria can oxidize. Dissolved oxygen in the water body depends on the temperature sediment and the oxygen input and output.

BOD and COD are correlated as both are the methods with the. On the other hand Chemical Oxygen Demand COD refers to the amount of oxygen needed to break down the pollutants chemically. BOD means biochemical oxygen demand And COD means chemical oxygen demand Simply explain BOD- the water pollution by organic waste in terms of biochemical oxygen demand.

To expand a bit on each of these. There are too many terms and it is getting confusing to me. BOD analysis is performed to determine what effect dirty.

COD is usually a measurement of chemicals and the. The Difference Between BOD and COD. Although COD and BOD have a high association COD analysis is a.
