what are the different types of water purification?

I've heard of reverse osmosis, but I'd say call the culligan man.

Fumigation. (but this is very expensive, not economical)\nLaunch a community program that encourages people to dispose water collections like cans, bottles, drums around their houses.\nEducate the community that containers that hold water should be closed with a lid (to avoid mosquitoes from breeding there) or be disposed of.

There are tons. Water filtration plants use catalysts, the exhaust on your car uses a catalyst. They are used extensivly due to their ability to readily interact and combine with complex organics.

i think most tap water contains fluoride, something bottled water companies filter out. seems that tap water is actually more regulated than bottled water.

1. underground water has more than river bed among it's sources. Other sources could be more polluted.\n\n2. Water, as it percolates through the rocks/sand etc dissolves/ leaches part of the salts/ compounds present in them.\n\n3. The water bearing strata itself could be made up of leach-able rocks\n\nNow. purifying it to potable standards:\na. let it stand for a while- undissolved solids likely to settle down\nb. pass it thru an alum bed- and allow moresettling down: more undissoved solids, conductive salts, calcium salts turbidity agents removed\nc. now, pass thru ACTIVATED CHARCOAL bed- to remove odour and some more chemicals.\n\nchances are your water now comes within permissible limits.\n\nIf not, u'll do well to \npass the whole thing thru RO(Reverse Osmosis) membranes-to remove microscopic solutes, \nsubject the water to aeration - to increase Oxygen content, \nand maybe even Ultra violet treatment- to kill most bacteria and other pathogens..\n\nRather than trial and error, U'll do well to go to a water consultant.

There are many different ways to make questionable water drinkable.\n\nBoiling- Bring it to a rolling boil (might want to leave it for 2 minutes just to be sure)\n\nChemical treatment- Outdoor stores carry products, follow package instructions\n\nFiltration- Water filters don't usually filter out virus' so chemical treatment is usually still needed\n\nUV light treatment- Special Lights are now on the market that can treat water in short time (See: http://www.bentgear.com/product_info.php?cPath=21_53_54&products_id=385)\n\nThere are other but not as common methods such as a machine that can produce chemicals that kill bacteria. \nHope I helped!

I know of at least 4 ways.  I think that the distillation or membrane separation are the most practical.\n\n(1)Distillation\nOxygen and nitrogen have different boiling points.\noxygen: 90 K\nnitrogen: 77 K\nIf you cool the mixture to a temperature between the boiling points of each you will be in a two-phase region.  There will be a gas phase rich in nitrogen (because it has a lower boiling point) and a liquid phase rich in oxygen.  A distillation column can be used to separate the phases and collect them in a continuous, pretty efficient process.  I think you have to do something special about the argon in air when you do this (like have more than one separation step, more than one distillation column).\n\n(2)Adsorption\nOxygen and nitrogen gases may adsorb to (stick to) the surfaces of certain compounds (like metal surfaces).  If you make a series of tubes lined with a substance that preferentially adsorbs (for example) oxygen, you will get a gas output that has less oxygen in it.  In a well-designed case, the adsorption is reversible.  Increasing the temperature of the substance will causes the oxygen to leave the solid surface and once again become a gas, giving you a relatively pure oxygen stream.  If the purity is not good enough, you can collect the streams and repeat the process (use a longer tube).  I don't know of an example of an adsorption material off-hand.\n\n(3)Stripping\nStripping is the process of passing a gas through a liquid and may involve chemically removing one of the components of the gas.  If you bubbled air through a liquid that had a chemical in it that reacted with oxygen to form a compound then the gas that reaches the top will be nitrogen-rich.  For example, your blood contains hemoglobin, so that when it is in contact with the air in your lungs the oxygen sticks to the hemoglobin, forming a chemical complex.  This is a lot more effective than limiting yourself to an oxygen supply based on whatever gases can dissolve in your blood. \n\n(4)Membrane Separation\nOxygen and nitrogen have different permeability in membranes.  They can diffuse through solids, but at different rates.  I think oxygen typically has high permeability.  If you pressurize the gas mixture and pass the gases through a bundle of tubes (high surface area is key) then some gas will pass through the tubes axially and some will diffuse through the walls radially.  The stream that passed through the tubes will be richer in nitrogen, since it is less permeable.  The stream that diffused through the walls of the tube will be richer in oxygen, becuase it is more permeable.  Repeat the process to get the desired purity.\n\nAn artificial lung can be made by passing blood through a long set of tubes that have oxygen on the outside of the tubes.  The oxygen diffuses into the blood through the permeable tubes.

tap water, while treated, still has some impurities. Distilled water has these impurities removed. Do a wikipedia search on tomato plants for all the properties you need.

A number of stages is necessary:\n\n1. Filtration - To remove particles, can be any filter.\n2. Odor removal - Use charcoal\n3. Ultraviolet treatment - To kill most germs\n4. Reverse osmosis
