whats the cheepest way to produce purifide water?

Answer 1

fill a pot with a few inches of water.
in the center of the pot place a empty cup that will not float.
cover the pot with aluminum foil
in the center directly over the cup place a small weight so the center is lower than the edges
boil the water.
as the water boils the water vapor will condensate on the aluminum foil and drip down into the cup leaving pure water in the cup.

Answer 2

If by purified you mean it has no germs in it, then you could either boil or freeze the water before you use it, this should kill any micro-organisms.

If you mean you want the water to be completely pure, and not have any other substances dissolved in it (which all water does) then the only way is to distill the water.

It is the most expensive way of treating water, and can be quite difficult to do if you do not have the correct equipment. Fisrt the water must be boiled, the steam then condensed and collected. This should give pure water since the substances in the water need a much higher temperature to become gas.

Answer 3

The cheapest u can get will be to use the chemical compound called ALUM....Its heavier than water andsoluble in water and when used, it dissolves in water and particles of ALUM get deposited on the impurities present in the water. As a result of this the impurities become heavier and they settle down to the bottom of the container. Later u can decant the pure water frm the top, leaving behind the impurities...

Answer 4

depends what the impurities are! If they are microbiological - say pond water - you can bang it through a filter. If the impurities are chemical, then you can still filter, but you need an active carbon filter as well.

If you ware talking dissolved salts, then it has to be distillation or reversed osmosis. Distillation with a solar still is in principle free -but etc etc. So , unless you are talking sea water, I go for filtration

Answer 5

That depends what you want the water for:

Drinking:- To remove particulate, filter it. To remove bacteria, boil it, to remove metal ions, distillation is cheapest or you could use ion exchange resins but are pricey.

Freshwater fish:- To remove harmful Chlorines, just leave the water overnight to 'breathe'. To remove Nitrates, again, use ion exchange resin.

Marine fish:- Reverse Osmosis is the cheapest but slowest method (marine fish need extremely pure water) and de-mineralisation is the fastest, best but most expensive.

For your iron/steamer to prevent scaling:- Distillation, ion exchange resin or commercially available water purifiers.

Answer 6

Heating is very expensive. The cheapest method has to be a process of filtration, floc formation and removal, secondary filtration and disinfection.

Answer 7

Boil the water and filter it thats the cheapest way and its the best way kills all known germs

Answer 8

Er do you want distilled water or just water with no bacteria?

Answer 9

Add the purification drugs that can be got from health units.

BRETTWARWICK good hit.
I`ve got about a teaspoon full in the time it`s taken to answer this question.
