Solar Pasteurized Water

The lack of clean water is a serious health problem in developing countries. To reduce these health risks of drinking water production rates is very important, people must be educated about the germs that contain water, it could again accidentally contaminate the drinking water they already have.

For those unfamiliar with the process of pasteurization of water is heating water to 75 ° C for about six minutes, so that germs, viruses, and parasites that cause human diseases are eliminated, including cholera and hepatitis A and B. this is very similar to what is done with milk and other liquids. It is not necessarily think recent boil water. Pasteurization is the only way to decontaminate water, but it is very difficult to practice with the initial costs are very low.

This new device which is called the solar puddle, and is basically a greenhouse puddle that pasteurizes water with solar energy, at the end of this article you can see an outline of how to build pool solar water pasteurization.

You start digging a hole about 15 cm deep. To achieve solar pasteurized water for a family, it is recommended to dig the pit of 1 m long by 1 m wide and 10 cm deep.

Then you need to put an insulating layer to the bottom of our well, you can do with grass, leaves or something. This insulating layer must be even except for one corner of the pit. It gets a double layer of plastic, first a transparent plastic, and then a black plastic covering the insulation layer and climbing the walls of the well to leave it. You put the two layers to minimize leakage to the fullest.

Put a little water and in pairs and the insulating layer with plastic so that the water depth is around 1.5 cm is true in the small heard the end of the shaft where the depth has to be about 2.5 centimeters. With more water in the well to have a depth of entre2.5 and 7.5 inches depending on how much sun is expected that day. It must put an indicator of pasteurization in the deep part of our well, and that’s where the coldest water is stored.

For another layer of clear plastic over the water, again the plastic must leave the pit. After you put a spacer, a small trunk is perfect and put three layers of plastic until the last remaining fully covering the well.

Already have built a solar water pasteurizer, just add water every day. The bottle you fill with water well should NOT be the same bottle with which Sachse water because it may contain bacteria on the walls. When the bottle while water extractor and the bullet with the same water pasteurization. In the tests conducted were obtained extract to 20 l of pasteurized water a day.
