This set of Bioseparation Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Filtration”.
1. Which bioseparation technique is used for separation of solid-liquid mixture through porous medium?
a) Filtration
b) Sedimentation
c) Centrifugation
d) Decantation
View Answer
Explanation: The bioseparation technique is used for separation of solid-liquid mixture through porous medium is filtration, it requires the feed to be forced through a porous medium on which the solids substances are deposited or entrapped.
2. What is called as filter in the filtration process of bioseparation techniques?
a) Non-Porous medium
b) Porous medium
c) Liquid medium
d) Solid medium
View Answer
Explanation: The filter in the filtration process of bioseparation techniques is a porous medium that allows the flow of liquid to while retaining the solids.
3. The retained solid after filtration is called filtrate.
a) True
b) False
View Answer
Explanation: The retained solid after filtration is called residue and the clarified liquid is called filtrate.
4. How many types of filtration are there in the bioseparation techniques?
a) 2
b) 4
c) 3
d) 5
View Answer
Explanation: There are three different types of filtration in the bioseparation techniques, they are cake filtration, clarification, cross flow filtration.
5. The filtration process which can filter slurry is called _______________
a) Filtration
b) Cross flow
c) Clarification
d) Cake
View Answer
Explanation: The process of filtration in bioseparation techniques is cake filtration that recovers the solids from slurry that contains high content of solid which can be separated from the waste in the form of cake.
6. The filtration process which can filter low weight solid is called ___________
a) Filtration
b) Cross flow
c) Clarification
d) Cake
View Answer
Explanation: The process of filtration in bioseparation techniques is clarification, in which the solid contents are separated based on the weight that should be less than 1%.
7. The filtration process which involves flow of liquid is called ____________
a) Filtration
b) Cross flow
c) Clarification
d) Cake
View Answer
Explanation: The process of filtration in bioseparation techniques is cross flow filtration. In this the liquid which needs to be separated is passed through the filter in the form of liquid and it flows in a parallel pattern to the medium which supports the filtration.
8. Which filtration is mainly used for the membrane filtration process of bioseparation?
a) Filtration
b) Clarification
c) Cake
d) Cross flow
View Answer
Explanation: Cross flow filtration is used in the process of membrane separation in the filtration process of bioseparation. It works on the basis of membrane been used for the separation of the liquid in the parallel form.
9. The process of filtration has no role in the biological industry.
a) False
b) True
View Answer
Explanation: The process of filtration is the major step of downstream processing after the fermentation broth is recovered from the fermenter. It plays a vital role to separate the impurities of the product which needs to be purified for further use or further marketing.
10. The applications of filtration include only recovery.
a) True
b) False
View Answer
Explanation: The applications not only include recovery of the products but also in clarification of the products as well as sterilization of the liquids.
