what,s happened when we boil polluted water.(which Com's from industries.?

Question

is apolluted water's strem allso polluted.

Answer 1

No one can give you a general answer.

Pollution is a general term. What is the pollutant is the question of concern. Let's say the pollutant boils at 50 deg C and it does not form an azeotrope with water that boils over 100 deg C. Chances are very good that it will be removed completely once the water temperature has exceeded 50 deg C. The water will boil at 100 C so in this case you have removed virtually all of the impurity.

Let's assume the pollutant boils at 135 deg C. Now water boil will have little influence.

You cannot generalize and this is why the issues are not simple.

Do not try this because there are a lot more variables to consider than mere boil point.

Answer 2

1. Water start evaporating.
2. Some pollutants remains dissolved or mixed at the liquid water or if water is completely evaporated remains at the bottom of the recipient used to boil the polluted water.
3. Some pollutants evaporate with the water and pass to the atmosphere.

Do the experiment, obserb results (ask help from parents if too young to operate the stove):
1. Boil heavy salted water.
2. Boil water mixed with soil, mud, dirt or sand.
3. Boil water mixed with vegetable oil.

Answer 3

boil it, distill it with a reasonable long fractioning column, filter thought activated charcoal and a UV lamp, then final microfiltration with micropore filters.

Then you have pure water, that you cannot drink because you will need to add some salts to it, otherwise your intestine walls will go in inverse osmosis and gives you a big abdominal pain.

Answer 4

Boiling water for twenty minutes will kill all organisms in the water but will not remove chemical pollutants.
You would probably have to distill it or filter through activated charcoal.
