Important Question And Answer: Sewer Design

 

 

1.  What are the Demerits of chemical precipitation?

 

 

        High cost of chemicals

 

        Large quantity of sludge which offers difficulty of its removal

 

        Skilled attendance

 

        Putrescible efficient

 

 

2.  What do you mean by chemical precipitation?

 

When certain chemicals are added to, sewage they produce a precipitate known as flow which in insoluble or slightly soluble in water. The flow attracts small particles to form large size and thus size goes on increasing during the process of settlement.

 

 

3. What is do you mean by transitional setting zone?

 

Grit particles however, generally lie between 0.1mm and 1 mm, and hence undergo settling which lies in between streamline settling and turbulent settling. This settling zone is called the transitional settling zone

 

 

4.What are the users of Baffle?

 

        Baffler are required to prevent the movement of organic matter and its escape along with the efficient

 

        Distribute the sewage uniformly through the cross section of the tank.

 

        It is used to avoid short circuiting

 

 

5.What are the classifications of biological process?

 

        Aerobic processes

 

        Anaerobic processes

 

        Aerobic �anaerobic processes


6.List out the aerobic processes?

 

        Activated sludge processes

 

        Trickling filters

 

        Aerobic stabilization pond

 

        Aerated lagoon

 

7.List out the anaerobic process?

 

        Anaerobic sludge digestion,

 

        Anaerobic contact processes

 

        Anaerobic filters

 

        Anaerobic lagoons or ponds

 

 

8.What are the sources of waste water?

 

        Domestic waste water (i.e sewage)

 

        Agricultural return waste water

 

        Industrial waste water

 

 

9.What are the methods involved in the treatment of waste water?

 

Mainly classified into

 

        Conventional treatment methods

 

        Advanced waste waster treatment

 

 

Conventional treatment methods

 

        Preliminary processes

 

        Primary treatment

 

        Secondary treatment

 

Advanced waste water treatment

 

Tertiary treatment

 

 

10.What are the functions involved in the chemical unit processes

 

        Chemical precipitation

 

        Gas transfer

 

        Adsorption

 

        Disinfection

 

        Combustion


11.What do you understand by waste water treatment?

 

The waste water treatment or sewage treatment is a broad term that applies to any process/operation or combination of processes and operations that can reduce the objectionable properties of water carried waste and render it less dangerous with the following.

 

 

        Removal of suspended and floatable material

 

        Treatment of biodegradable organics

 

Elimination of patheogenic organisms
