CAPF AC 2021 Q123: Current Affairs – Indian Government Schemes & Initiatives

CAPF AC 2021, Paper I (General Ability and Intelligence) · Current Affairs

Scientists at CSIR-NCL Pune, with support from the Water Technology Initiative of the Department of Science and Technology (DST), Government of India, have recently developed a novel hybrid technology to bring safe and healthy drinking water. What is the name of the hybrid technology?

(a) SafeWater
(b) SWASTIIK
(c) Arsiron Nilogon
(d) Fluoride Nilogon

Answer: (b) SWASTIIK

Explanation

SWASTIIK water technology

How to think: the name is an acronym built to sound Indian.

SWASTIIK stands for Safe Water and Sustainable Technology Initiative from Indian Knowledgebase.

It was developed at CSIR-National Chemical Laboratory (NCL), Pune.

Feature	Detail
Developed by	CSIR-NCL, Pune, with DST's Water Technology Initiative
Main method	Hydrodynamic cavitation: the liquid is made to boil by reducing pressure
Hybrid part	Combined with natural oils and plant extracts that kill germs (Ayurveda)
Result	Removes harmful bacteria, including drug-resistant ones, at low cost

Why it is better than chlorine: chlorination can leave harmful by-products.

This method avoids them.

The Nilogon options: Arsiron Nilogon is a low-cost method from Tezpur University to remove arsenic and iron.

Answer: (b) SWASTIIK.

Why each option is right or wrong

(a) Incorrect. SafeWater is a general term, not the name of this technology.
(b) CORRECT. The CSIR-NCL hybrid technology is called SWASTIIK.
(c) Incorrect. Arsiron Nilogon removes arsenic and iron; it came from Tezpur University.
(d) Incorrect. Fluoride Nilogon removes fluoride; it is also from Tezpur University.

Key point

SWASTIIK: CSIR-NCL Pune, hydrodynamic cavitation plus natural oils, safe drinking water without chlorine by-products. Arsiron Nilogon and Fluoride Nilogon: Tezpur University, Assam.

Remember

SWASTIIK: CSIR-NCL Pune, cavitation + natural oils.

Common mistakes

Marking Arsiron Nilogon, an older Assam technology for arsenic removal.
Thinking the method is a filter membrane; it uses cavitation.
Confusing CSIR-NCL (Pune) with CSIR-NEERI (Nagpur), which works on environment.

Exam tip

Educated guess: the question mentions Indian knowledge in spirit (natural oils, Ayurveda). A name like SWASTIIK, ending in Indian Knowledgebase, fits that idea.
