This set of Bioseparation Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Theory of Filtration”.
1. What is the significance of the given diagram?
a) Clarification
b) Cake filtration
c) Cross flow filtration
d) Filtration
View Answer
Explanation: The feed is subjected to the medium of filtration from the above and the filtrate the collected from the bottom of the filtration chamber. The whole process is performed in a bed like structure that’s why it is termed as cake filtration.
2. What is the significance of the given diagram?
a) Clarification
b) Cake filtration
c) Cross flow filtration
d) Filtration
View Answer
Explanation: The products to be separated are passed through the membrane and are collected at the end of the filtration process. The medium is very thin and it clarifies the product which has weight less than 1% of the product.
3. What is the significance of the given diagram?
a) Clarification
b) Cake filtration
c) Cross flow filtration
d) Filtration
View Answer
Explanation: The product is in the form of liquid and is passed through the membrane in a parallel pattern through the filtration set up and the filtrate is collected from the bottom at the end of the process of filtration.
4. What is the significance of the given diagram?
a) Clarification
b) Cake filtration
c) Cross flow filtration
d) Surface filtration
View Answer
Explanation: The product is being filtered from the surface of the medium placed for the separation n of product and the waste.
5. What is the significance of the given diagram?
a) Clarification
b) Cake filtration
c) Cross flow filtration
d) Surface filtration
View Answer
Explanation: The product is allowed to pass through the pores of the membrane which helps in the filtration process and the wastes are retained in the membrane within the pores and the filtrate are separated from the medium.
6. Which filtration methods are based on Surface filtration?
a) Clarification
b) Cake filtration and cross flow
c) Cross flow filtration and cake
d) Surface filtration
View Answer
Explanation: In surface filtration the particles are retained by the screening of the wastes through the membrane and are held on the external surface of the filter.
7. Which filtration method is based on depth filtration?
a) Clarification
b) Cake filtration and cross flow
c) Cross flow filtration and cake
d) Surface filtration
View Answer
Explanation: The particles required to be separated are subjected to the membrane and are allowed to penetrate the pores of the membrane as well as the network of the pore within the medium in the depth filtration which works for the clarification method of filtration in bioseparation technology.
8. The particles in the medium of depth filtration are retained based on __________
a) interception, diffusion
b) impaction, inception
c) diffusion
d) interception, impaction, diffusion
View Answer
Explanation: The membrane retains the particles within itself due to the action of various mechanisms involved in the process. The mechanisms are direct interception, diffusional interception and inertial impaction.
9. What happens to the particle in direct interception?
a) Gets trapped
b) Floats
c) Settles
d) Penetrate
View Answer
Explanation: In the direct interception the particles enters the pores within the membrane and get trapped in the pore diameter and becomes equal to the particle diameter.
10. Particles being carried by fluids have ___________
a) Momentum
b) Velocity
c) Acceleration
d) Speed
View Answer
Explanation: The particles in the filtration medium when subjected to the filtration are being carried by fluids which have momentum on account of mass and velocity of the moving particles.
