- Dissolved oxygen is measured by the Winkler titration method.
- BOD5 is measured by putting a known volume of bacteria in a sample of the fluid to be insppected at the saturation point of oxygen, keeping it at a specified temperature for 5 fays then measuring the oxygen content.

Why you use blank for the BOD test?
In the BOD (Biochemical Oxygen Demand) test, a blank is used to account for any oxygen demand exerted by materials other than the sample itself, such as the reagents and the dilution water. This ensures that the measured BOD reflects only the oxygen consumed by the biodegradable organic matter present in the sample. By subtracting the BOD of the blank from the sample's BOD, the results provide a more accurate assessment of the sample's organic pollution load.
What is the formula to get the BOD to COD Ratio?
The BOD to COD ratio is calculated using the formula: [ \text{BOD to COD Ratio} = \frac{\text{BOD}_5}{\text{COD}} ] where (\text{BOD}_5) is the biochemical oxygen demand measured over a 5-day period, and COD is the chemical oxygen demand. This ratio helps assess the proportion of biodegradable organic matter in wastewater; a higher ratio indicates a higher level of biodegradable material.
Why does chlorine increased the numbers of COD and BOD in the wastewater?
No, not increasing because it is not reducing oxygen.But it can alter the measured BOD and COD rather unpredictable possibly by decreasing BOD and in- or de-creasing COD
How is the mineral content of the body measured?
The mineral content of the body may be measured by testing samples of blood plasma, red blood cells, or urine.
What is meant by BOD loading rate?
BOD loading rate refers to the amount of biological oxygen demand (BOD) entering a body of water over a specific time period, usually measured in terms of mass per unit time (e.g., mg/L/day). It is used to assess the impact of organic pollutants on water bodies and their ability to support aquatic life.
Simply discuss the factors that affect the BOD value in the experiment?
The factors that can affect the biochemical oxygen demand (BOD) value in an experiment include the organic matter concentration in the sample, the microbial population present to break down the organic matter, the incubation time of the sample, and the temperature at which the incubation occurs. These factors can influence the rate at which oxygen is consumed in the sample, affecting the final BOD value measured.
