How to build a water purification system by yourself?

a simple distillation unit can be made using a bucket or nother resevior and placing plastic or plexiglass slightly above it at an angle that will direct the water that condensates on the glass into another container. this however will only remove the minerals. the water changes to a gas and then condense on the glass into a liquid again, the minerals do not

Thats simple! Boil some water

We have an aquabug. You just put it in and it goes by itself. Works pretty good.

some good projects for kids are at-http://pbskids.org/zoom/activities/sci/\nthese might be too easy for anyone older than a 3rd grader, but they're still something!\n my little brother is doing the water filter.  he's going to see which of the materials filters water best. good luck! :)

Do you mean demineralized water?\n\nReverse osmosis is the most economical way.\n\nCheck out millipore, look up their RO products.

1. The EPA has set maximum amounts of contaminents for drinking water. here is a table http://www.water-research.net/standards.htm\n\n2. You could use ultra-violet, this works well, also ozination.\n\n3. A gallon jug of household bleach down the well casing usually does the job. After dumping the bleach in, run water at every spigot in the house until you smell bleach. shut water off and let sit for 12 hours, then run water until color is clear and smell has dissipated.\n\n4> ?

With a water softener.\n\nhttp://en.wikipedia.org/wiki/Water_softener

you could do a project of 'rain harvesting'\nconstruct a house,surrounded by a small canal -shaped tank which can hold water when it rains use this water (after purification)for various odd uses.\nit works if you use small plastic tubes as canals\n    OR\n a sugarcane industry is a very good idea(i got a prize for this.)\nbut you need to make crusher,purifier,separator,and drier made of steel or iron.

The best thing would be a bit of bleach.  Do the math - you should shoot for about 2 to 4 parts per million hypochlorite (since commercial preparations are usually 5% - which is 50,000 parts per million - YOU NEED TO DILUTE IT 25,000 FOLD BEFORE YOU DRINK IT - SEE MY NOTE AT THE BOTTOM).  You should also try to store the water in the dark, in an opaque container, or at least in a brown or green glas container since algae growth is photosynthetically driven (i.e. needs light)\n\nBE CAREFUL HANDLING BLEACH - AT HIGH CONCENTRATIONS IT IS TOXIC AND CORROSIVE.

first vapour it all if there is no rubber monomer vaporize then try a distilation tower with hysys if u want i can simulate it for u?

There is a product made by HTH called pH Minus. (I'm sure there are other company's that make it as well), it's fairly inexpensive, around $14.00 for 1/2 gal. Just follow the directions and your water will be back to normal in no time at all. It works quickly! GOOD LUCK!

I'm gonna take a stab at this, though your question is a little difficult to understand.\n\nMy bet is your wondering how to reduce the scaley mineral buildup that could build up in water condensers.\n\nThe first step would be prevention. Eliminate the minerals from the cooling water. Use Distilled water, which, because of the process of distilling, is infact pure water.\n\nSecondly, if mineral buildup occurs, you would need to clean the condensers with some type of chemical cleaner, designed to react with the mineral buildup and dissolve it. There are a number of commercial products availble - most are simply really strong acids, such as phosphoric acid or HCl.  CLR and Limeaway are two common products.

Purify it. And then have it in a closed system where nothing can get to it

basically you're talking about distilling water, which is a purification technique.  collect the water vapor and let it condense. the result is pure water.

Here is what I would suggest.  First let the water stand still for a while to settle heavy particle as sand, pebbles, rocks etc.  Then using coffee filter or thick paper towel, decant water.  That should take care of smaller stuff.  Then you use fine powder charcoal and add to your water (filterate).  Let it sit for 10 minutes and stirr occasionally.  Then filter the water using coffee filter or paper towel and you will have odor free-clear, very pure (~ 99%+ water) that can be used for drinking.  If you want absolute pure, before charcoal step, heat the water to boil, cool and then do charcoal step and you will have killed all bio organisms also.

If you mean is all clear, cold, colorless water good for the purification process to become drinking water, then your answer is not always.  There are many clear and colorless chemicals that can make it through the purification process with out being removed.  A series of tests should be administered to the water to find out exactly what's in there so that the appropriate purification process can be applied.
