When camping or hiking, or even at home and your water supply becomes contaminated, it may we wise to know how to make a water purifier to eliminate the possibility of getting sick from bad water, or not having purified water available.
Before you can understand how to make a water purifier, you should know what causes water to be unhealthy. Most surface water from lakes, rivers and streams contain disease-carrying microorganisms such as protozoa, bacteria and viruses. There are also man-made contaminants from different sources such as manufacturing, poor waste disposal methods and air pollution.
There are four methods to kill the microorganisms and remove unwanted pollutants in the water. Boiling, chemical, filtering and solar, or ultraviolet light, are how to rid the water of unhealthy bacteria. Boiling has been a time-tested means of removing disease-causing microorganisms from the water, if done correctly. If you understand distillation, you will know how to make a water purifier Water must reach a boiling temperature of 185-degrees Fahrenheit for at least one minute to be effective.
Chemicals most commonly used are iodine and chlorine. Both are effective at killing the organisms, but have no effect on the appearance of the water, and they do affect the water’s taste. Filtering can also be used but you need the right knowledge of the microorganisms to know how to make a water purifier.
Filtering Germs Requires Small Filters
Protozoa are typically five microns in size and a four-micron filter will generally remove them. Bacteria usually run from .2 to .5, requiring a filter size not bigger than 1 to .2 micron filter rating. Viruses, such as type that cause hepatitis, rotavirus and the Norwalk Virus are about .004-microns and require that size filter to be effective.
To make a solar still, a container to catch the water and a clear plastic sheet to cover it is needed to use this method of how to make a water purifier. The sun’s ultraviolet waves going through the plastic will essentially distill the water killing most disease-causing microorganisms. It may be a good idea, if available, to use water purification tablets as well.
Wet clay can be used in knowing how to make a water purifier, as a filtering device using ceramics; glass fibers or materials like surgical papers (masks) can be useful in filtering microbes from the water. By filtering the water through the tightest available screening materials you not only, remove the physical contaminants, but most of the microorganisms as well.
