Solution
The correct option is C Fermentors
Large scale production of beverages and antibiotics :
Commercially important products like beverages and antibiotics are manufactured through the process of fermentation on a large scale in controlled conditions. This process, therefore, requires a large vessel called fermentor.
Definition of fermentor :
Large vessels (volume from 100L to 1000L) usually made up of stainless steel, in which various raw materials are acted upon by desired microbes, to produce economically important products are called fermentors.
Settling tanks :
Settling tanks are used in the primary treatment of sewage where the suspended and heavy impurities settle to form primary sludge. The supernatant, called primary effluent, then undergoes secondary treatment.
Besides, settling tanks are also used after the secondary treatment of water to allow the sedimentation of bacterial flocs and form activated sludge.
Biovessel :
A biovessel is an indoor composter that can be used by individuals to convert food waste into fertilisers through the use of earthworms.
Agitator :
Agitator consists of motorised blades that are used to aerate the primary effluent during the secondary treatment of sewage.
Final answer :
(B) Fermentors
