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:

A passage is given with 5 questions following it. Read the passage carefully and choose the best answer to each question out of the four alternatives.


The quest to find life outside the solar system got a big boost with the discovery of seven Earth-size extra-solar planets, or exoplanets, orbiting a dwarf star about 40 light years away. Unlike earlier discoveries of exoplanets, all seven planets could possibly have liquid water — a key to life as we know it on Earth — with three planets having the greatest chance. This is by far the largest collection of Earth-like planets in the habitable 'Goldilocks' zone of a star — neither too close nor too far from a star, which raises the possibility of liquid water being present on the surface. Only Earth has liquid water in the solar system. Since the dwarf star is much cooler than the Sun, the dimming of light each time a planet passes or transits before the star could be easily recorded from Earth unlike in cases when planets transit a Sun-like bright star. Since the initial discovery of three planets was made using the Chile-based Transiting Planets and Planetesimals Small Telescope, the exoplanet system is called TRAPPIST-1.

 

What is the 'Goldilocks' zone?

A) It is a mythological place about stars and planets B) That place on a planet which has lowest possibility of liquid water.
C) The correct distance of a planet from its star to have possibility of having liquid water D) That place on a planet which has the right amount of sunlight
 
Answer & Explanation Answer: C) The correct distance of a planet from its star to have possibility of having liquid water
