This set of Applied Chemistry Multiple Choice Questions & Answers (MCQs) focuses on “Permutit’s Process”.
1. Zeolite process is also called as __________
a) Permutit’s process
c) Batch’s process
d) Lime soda process
Explanation: The zeolite process is also called as the permutit’s process. The zeolite process is very useful to remove the hardness of water.
2. The capital cost of the zeolite process is ___________
c) Very high
d) Very low
Explanation: The capital cost of the zeolite process is very high. The operational cost of the zeolite process is low.
3. The zeolite process is used for turbid process.
Explanation: The zeolite process cannot be used for the turbid process. The zeolites are naturally occurring sodium aluminium silicates.
4. How many steps are involved in the zeolite process?
Explanation: There are no steps involved in the zeolite process. The water hardness will be removed in one operation in zeolite process.
5. In zeolite process, the dissolved ________ is not removed.
Explanation: The dissolved carbondioxide is not removed during the zeolite or the permutit’s process. It can be removed in the lime soda process.
6. The exchange medium in the zeolite process is ___________
b) Cannot be regenerated
c) Regenerated when medium hard water is introduced
d) Regenerated when very hard water is introduced
Explanation: The exchange medium in the zeolite process can be regenerated. Reagent used in the lime soda process cannot be regenerated.
7. In zeolite process, only small amount of ________ ions can be removed.
c) Both Fe++ and Mn++
d) Neither Fe++ nor Mn++
Explanation: In zeolite process, only small amount of the Fe++ and Mn++ are removed. The total amount can be removed by using the lime soda process.
8. Zeolite process cannot soften _________
a) Basic water
b) Neutral water
c) Acidic water
d) Salt water
Explanation: Zeolite process cannot soften the acidic water. After the process, the sodium salts are not useful for the boiler use.
9. The hardness of the water in the zeolite process can be treated at the range of __________
Explanation: The hardness of the water in the zeolite process can be treated at the range of the 5-15ppm. The regenerated zeolite can be used to remove the calcium and magnesium ions from the water.
10. __________ should be free of turbidity as they interfering in exchange process.
a) Raw water
b) Hard water
c) Very hard water
d) Soft water
Explanation: Raw water should be free of turbidity and suspended impurities as they are interfering in the exchange process.
11. Very low hardness of __________ can be achieved in the zeolite process.
d) Less than 5ppm
Explanation: By careful monitoring it will be possible to achieve the very low hardness of the less than that of 5ppm can be achieved in the zeolite process.
12. Variation of hardness of raw water in zeolite process _________
a) Do not affects the exchange process
b) Affects the exchange process
c) Slightly affects the exchange process
d) Some times affects the exchange process
Explanation: Variation of hardness of raw water in zeolite process do not affect the exchange process because according to it zeolite bed changes automatically.
13. The zeolite process can be __________
a) Can be operated pressure
b) Cannot be operated under pressure
c) Can be operated under pressure sometimes
d) Cannot be operated under pressure sometimes
Explanation: The zeolite process has the best advantage than any other processes that it can be operated under the pressure also.
14. __________ water is not suitable for zeolite process, as it affects the mineral.
a) Highly acidic
b) Highly alkaline
c) Highly acidic and alkaline
d) Neither highly acidic nor alkaline
Explanation: The highly acidic or alkaline water is not suitable for zeolite process, as it affects the mineral. It is one of the limitations of this process.
15. NaOH formed during zeolite process is reacts with _________ at high temperatures causing the corrosions of boilers.
Explanation: NaOH formed during the zeolite process reacts with the iron at high temperature during the process that leads to the corrosion of the boilers.
