The correct Answer is:
To determine the correct ascending arrangement of BOD (Biochemical Oxygen Demand) for sewage (S), distillery effluent (DE), paper mill effluent (PE), and sugar mill effluent (SE), we need to first understand the BOD values for each type of effluent. ### Step-by-Step Solution: 1. **Understand BOD**: BOD stands for Biochemical Oxygen Demand, which measures the amount of oxygen consumed by bacteria and microorganisms while decomposing organic matter under aerobic conditions. Higher BOD values indicate a greater amount of organic matter present. 2. **Identify BOD Values**: - **Sewage (S)**: BOD ranges from 300 to 600 mg/L. - **Distillery Effluent (DE)**: BOD ranges from 40,000 to 50,000 mg/L. - **Paper Mill Effluent (PE)**: BOD ranges from 176 to 282 mg/L. - **Sugar Mill Effluent (SE)**: BOD is approximately 3480 mg/L. 3. **Arrange BOD Values in Ascending Order**: - The lowest BOD value is from **Paper Mill Effluent (PE)**: 176 to 282 mg/L. - Next is **Sewage (S)**: 300 to 600 mg/L. - Then comes **Sugar Mill Effluent (SE)**: 3480 mg/L. - Finally, the highest BOD is from **Distillery Effluent (DE)**: 40,000 to 50,000 mg/L. 4. **Final Arrangement**: - The correct ascending arrangement of BOD is: 1. Paper Mill Effluent (PE) 2. Sewage (S) 3. Sugar Mill Effluent (SE) 4. Distillery Effluent (DE) ### Final Answer: **Ascending Arrangement of BOD**: PE < S < SE < DE

In which one of the following, the BOD (Biochemical Oxygen Demand) of sewage (S), distillery effluent (DE), paper mill effluent (PE) and sugar mill effluent (SE) have been arranged in ascending order ?

Assertion : Cultural eutrophication is nutrient enrichment of water bodies due to human activities like passage of sewage, industrial effluents, etc. Reason : The prime contaminants from sewage and industrial effluents are nitrates and phosphates, which act as plant nutrients and overstimulate the growth of algae.

Which is correct matched ? 1. Arsenic poisoning -Black foot disease. 2. Secondary Effluent treatment-Biological process. 3. Pyrolysis -Solid soil waste disposal. 4. Tubifex -Water pollution indicator. 5. Biomagnification -Degradable pollutants.

Which of the following statements regarding eutrophication are correct ? (i) Eutrophication is the natural ageing of a lake by nutrient enrichment of its water. (ii) Pollutants from human activities like effluents from the industries and homes can radically accelerate the aging process of a lake. This phenomenon is called as cultural or accelerated eutrophication. (iii) The plant nutrients responsible for eutrophication are nitrates and phosphates. (iv) These phosphates and nitrates accelerate the growth of algae, which utilise oxygen and may deoxygenate the water to kill the fish and other aquatic animals.

Given below are the steps involved in sewage treatment. Arrange them in proper sequence and select the correct option. A. Passage of primary effluent into large aeration tanks for mechanical agitation and pumping of air. B. Passage of secondary effluent and formation of activated sludge. C. Physical removal of particles through filtration and sedimentation D. Release of effluent from the secondary treatment plant into natural water bodies. E. Growth of useful aerobic microbes into flocs which significantly reduce the BOD.

Large quantities of sewage is generated everyday in cities and towns, which is treated in Sewage Treatment Plants (STPs) to make it less polluted. Given below is the flow diagram of one of the stages of STP. Observe the given flow diagram and answer the questions accordingly (a) Why primary effluent is passed into large aeration tanks? (b) Write the technical term used for the sediment formed? Mention its significance (c) Explain the final step that results in the formation of biogas in the large tank before the treated effluent is released into water bodies.

Read the following statements w.r.t. biological treatment of sewage. Br a. Involves removal of sewage through sequential filteration. Br b. BOD of waste water is directly proportional to its a polluting potential. Br c. Constant agitation of primary effluent is carried out in large aeration tanks. Identify the incorrect statement(s)
