How to make water filter
 | Why are you looking for a home made water purifier? Are you doing a science project? Are you a science teacher? Or, do you really have a problem with contamination? If your answer to the latter is "yes", I'll have some information for you later on, but first let's look at the science project. If you want to built a home made water purifier to demonstrate some of the principles of water purification, you only need a few common household items; two large mixing bowls, a sturdy square cardboard box about 1 foot high, 4 and a half feet of yarn (preferably white) cut into one and one half foot lengths and braided to form a rope and dirty water. how to clean water The demonstration works best if you have a mud hole or a stagnant pond to get water from. You need to put one bowl on top of the box. The other goes on the table or floor. One end of the yarn rope goes in each bowl and the dirty water goes into the bowl on top. Eventually, the yarn rope will absorb the water, but the dirt will be left behind. This home made water purifier demonstrates the principles of simple filtration. It also demonstrates absorption and it gets a little help from gravity. You could repeat the demonstration with bowls on the same level, in order to show how gravity helps the cleaner water travel down the rope and into the second bowl. If they are on the same level, the water will drip off of the rope and into the spot between the bowls. If you are a science teacher, you may want to schedule a tour of your local treatment facility after you complete the home made water purifier demonstration. That kind of tour made a big impression on me, during my childhood. Your students may begin to appreciate water more and start to understand the concepts of conservationism. We have a limited number of resources on this planet. Freshwater is one resource that we can hardly afford to waste. If you have a problem with contamination, then a home made water purifier is probably not the right choice. In an emergency situation, such as following a flood or hurricane, you should boil if you have electricity, but it is best to be prepared by storing clean water ahead of time or keeping a case of bottled on hand. If you store your own, you will need to replace it every six months. If you use plastic containers, you should store in an area away from toxic substances, such as gasoline or pesticides, because the vapors may be able to penetrate the plastic. If you've forgotten to "be prepared", you can use unscented household chlorine bleach. The CDC recommends an eight of a teaspoon per gallon if the water is clear and three quarters of a teaspoon, if there is some cloudiness. Mix thoroughly and let stand for 30 minutes before use. You can also opt to keep chlorine or iodine tablets on hand, but many parasitic organisms will not be killed by them or chlorine bleach. As long as you still have service, your kitchen faucet filter will still be working and as long as it has sub-micron particle filtration, additional steps may be unnecessary, but if possible, filter and then boil. A home made water purifier is not adequate to handle emergency needs. How to make water filter |
