Q:

Tertiary sewage treatment is designed to remove

A) Calcium and Phosphorous B) Nitrogen and Calcium
C) Phosphorous and Nitrogen D) Calcium and Nitrogen
 
Answer & Explanation Answer: C) Phosphorous and Nitrogen

Explanation:

Sewage treatment generally involves three stages, called primary, secondary and tertiary treatment.

Primary treatment consists of temporarily holding the sewage in a quiescent basin where heavy solids can settle to the bottom while oil, grease and lighter solids float to the surface. This removes material that will either float or readily settle out by gravity. It includes the physical processes of screening, comminution, grit removal, and sedimentation.

 

Secondary treatment removes the soluble organic matter that escapes primary treatment. It also removes more of the suspended solids. Removal is usually accomplished by biological processes in which microbes consume the organic impurities as food, converting them into carbon dioxide, water, and energy for their own growth and reproduction.

Tertiary treatment includes removal of nutrients such as phosphorus and nitrogen and practically all suspended and organic matter from waste water.

Q:

Read the following passage carefully and choose the most appropriate answer to the question out of the four alternatives.

 


In short, to write a good letter you must approach the job in the lightest and most casual way. You must be personal, not abstract. You must not say, 'This is too small a thing to put down'. You must say, 'This is just the sort of small thing we talk about at home. If I tell them this they will see me, as it were they'll hear my voice, they'll know what I'm talking about'. That is the purpose of a letter. Carlyle had the trick to perfection. He is writing from Scotsbrig to his brother Alec in Canada and he begins talking about his mother. Good old Mother, he says, 'she is even now sitting at my back, trying at another table to write you a small word with her own hand; the first time she has tried such a thing for a year past. It is Saturday night, after dark; we are in the east room in a hard, dry evening with a bright fire to our two selves; Jenny and her Barns are 'scouring up things' in the other end of the house; and below stairs the winter operations of the farm go on, in a subdued tone; you can conceive the scene! How simple it is and yet how perfect. Can not you see Alec reading it in his far-off home and his eyes moistening at the picture of his old mother sitting and writing her last message to him on earth?

 

Subdued tone means _______.

 

A) not very loud B) unusually quiet and possibly unhappy
C) not very busy D) not very bright
