Let’s start

Question 01.

what is the main role of clarifier in sewage treatment?

Previously Asked in : SKUAST Civil Engineer Civil (post code: 71) ||

To separate solids from liquids

To provide a platform for biological growth

To add chemicals to the sewage

To filter out large debris

Solution (Detail solution is below)

option To separate solids from liquids is correct

Detailed Solution :

The main role of a clarifier in sewage treatment is to separate suspended solids from liquid effluent through sedimentation.

This process helps to improve water quality and ensure that the water meets regulatory standards for discharge

some other roles of a clarifier in sewage treatment:

Removes floating matter
Produces sludge
Stabilizes flow

Correct option is: To separate solids from liquids

Question 02.

A major disadvantage of using chlorine for disinfection in sewage treatment is that

Previously Asked in : SKUAST Civil Engineer Civil (post code: 71) ||

It can form harmful by-products

It is ineffective against viruses

It does not kill bacteria

It is too expensive to use

Solution (Detail solution is below)

option It can form harmful by-products is correct.

Detailed Solution :

Advantages of Chlorination of Water

Kills harmful and pathogenic microorganisms.
Prevents waterborne diseases.
Maintains water quality during distribution.
Provides residual protection.
Cost-effective water treatment method.

Disadvantages of Chlorination of Water

Unpleasant taste and odour.
Formation of potentially harmful disinfection byproducts.
Allergic reactions in some individuals.
Corrosive to certain materials and equipment.
Limited effectiveness against some parasites and viruses.

Question 03.

Which analytical method is commonly used to measure and analyze particulate matter in ambient air samples?

Previously Asked in : SKUAST Civil Engineer Civil (post code: 71) ||

Scanning Electron Microscopy (SEM)

High-Performance Liquid Spectrometry (HPLC)

Differential Optical Absorption

Ga Chromatography-Mass (GC MS)

DOAS

Solution

option Scanning Electron Microscopy (SEM) is correct (Detail solution is below)

Detailed Solution :

Scanning Electron Microscopy (SEM) is one of the most useful techniques of examination of PM in environmental samples involving air.

Scanning Electron Microscopy (SEM) allows to study the form of particles and their elemental content.

This method has an advantage in producing images that are of high resolution for both the dimensions of the particles and their surface structures.

In the case of Scanning Electron Microscopy, it utilizes the appropriate focused electron beam to bombard the particulate matter as its distinguishing vessel.

This channel produces secondary electrons from the particulate matter which is accessed by the image of the sample that looks for the interaction with the particulate matter. Additionally, energy dispersive x-ray

Question 04.

Which of the following noise metrics is most commonly used to assess long-term exposure to environmental noise and its impact on human health

Previously Asked in : SKUAST Civil Engineer Civil (post code: 71) ||

Day-night Average sound level

Peak sound level

Sound exposure level

Equivalent continuous noise level

Solution (Detail solution is below)

option Day-night Average sound level is correct
