This set of Bioseparation Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Filter Medium used in Filtration”.
1. The function of filter medium is to ___________
a) barrier
b) supporter
c) cleaner
d) clarifier
View Answer
Explanation: The filter medium is primarily used as an impermeable barrier for the separation of the particulate matter from the solution to be filtered.
2. The barrier present in the clarification process is __________
a) solution
b) solvent
c) filter medium
d) filtrate
View Answer
Explanation: The filter medium acts a barrier to the process of clarification, as the solution to be clarified passes through the medium the sample gets stuck in the medium and it causes loss of some amount of filtrate.
3. At which stage of the filtration process, the filter medium acts a barrier?
a) End
b) Before the process
c) Between the process
d) Beginning of the process
View Answer
Explanation: The filter medium acts as a barrier in the process of filtration during the beginning of the process, since the medium initially retains the sample. After sometime, the medium becomes accustomed with the sample so it does not cause any barrier in the process.
4. During which stage cake becomes the main retainer of particles?
a) Cake formation
b) Cake completion
c) Cake disruption
d) Clarification
View Answer
Explanation: The commencement of cake formation makes the cake, the main particle-retaining barrier in the process of filtration.
5. At which stage the role of filter medium becomes the supporter in the process of flitration?
a) Cake completion
b) Cake formation
c) Cake disruption
d) Clarification
View Answer
Explanation: The filter medium acts a support for the cake during the formation of cake in the process of filtration once the barrier action of filter medium is settled.
6. What shall be the property of a filter medium?
a) Chemical strength
b) Biological strength
c) Mechanical strength
d) Filtration strength
View Answer
Explanation: The filter medium should be mechanically sufficient strong and it must be resistant to the corrosive action of fluids which can offer low resistance to the flow of the filtrate.
7. Various filter medium available in the market are ___________
a) filter paper
b) cheese cloth
c) ceramics
d) filter paper, cheese cloth, ceramics
View Answer
Explanation: The various filter mediums available in the market are filter paper, cheese cloth, woven polymer fiber, woven glass fiber, non-woven fiber pads, sintered as well as perforated glass, sintered as well as perforated metal, ceramics, and synthetic membranes.
8. The filter membrane should not be resistive to the corrosion.
a) True
b) False
View Answer
Explanation: It should have sufficient resistant to the corrosive nature of the fluids which are being used in the process of filtration.
9. The various woven material which can be used as filter membrane are ___________
a) cheese cloth
b) polymer fiber, cheese cloth
c) glass fiber
d) cheese cloth, polymer fiber, glass fiber
View Answer
Explanation: The woven materials used as filter membrane include all the substance which have woven property and are porous enough for the separation of filtrate with the raffinate.
10. Most filtration process relies on the filtration process which have ____________
a) depth nature
b) low depth
c) diffusional nature
d) random distribution
View Answer
Explanation: The depth nature of filtration process are the most common filtration method which uses the filter bed for the formation of cake and retains the filtrate in the cake and final separation of the filtrate as well as raffinate.
