What is packaged drinking water?

Answer 1

Packaged drinking water is usually spring water that has been filtered in a plant and then bottled.

Water is processed through :-

1. Prefilteration - usually sand-carbon filter

2. Membrane Filteration - Reverse Osmosis Technique

3. Post Filteration :- Microfilters + Ultraviolet [ UV ] treatment

4. Some times Ozonation too

Then it is Bottled OR put in Jars or pouches, packaged, hence packaged drinking water.
