Quality Water Filters 4 You Posting Page
Wednesday, December 26, 2012
The closer you get to the equator, the warmer waters are, and the more microbes, protozoans, bacteria, viruses, amoebae, and other small but hazardous creatures can thrive in them, raising a need for water filters and other robust water treatment measures. The tropics holds many treasures, both natural and man-made, but a wise inhabitant or visitor will also take precautions to ensure that the most vital physical resource, water, doesn't do them harm.
   
Whether you are on an exciting safari in Africa, perhaps wielding a camera rather than a gun, in South America to attend an important business conference, or live in one of the warmer countries, drinking unfiltered water puts you at serious risk. Bacteria, viruses, parasites, and chemical pollutants abound in the warm soup of many warm equatorial fresh waters.
   
The best approach to water safety in the tropics is to process your drinking water several times, in different ways, before you set it your lips. Using a purifying tablet or liquid treatment kills all organisms reliably, as does bringing all water to a rolling boil before using it. However, neither of these approaches removes poisonous industrial chemicals from the water. On the flip side, filters take out chemicals and larger organisms, but are less effective against viruses.
   
The first step in making tropical water potable is to put it through a good quality filter, with a 1 micron or finer structure of pores or channels. This takes out cysts, parasites, protozoans, and a large portion of the bacteria. It also filters out debris, silt, colors, odors, heavy metals, and most industrial chemicals that might have found their way into the local water supply.
   
After the water has been filtered, treat it with iodine tablets or with the specially formulated chlorine additives designed for hikers. This chlorine has a very different structure from bleach, which has been used as a cleansing water additive but is fairly unpleasant in its own right. This wipes out any surviving organisms, including those that might have been in the container the water is filtered into.
   
Portable Reverse osmosis water filters are among the best for dealing with water in Africa and other regions where practically every drop of water is possibly teeming with dangerous microorganisms. If you live in one of these countries, you will have little problem installing a reverse osmosis filter in your home's water system. However, if you are traveling there, matters are a little trickier.
   
For serious water safety while traveling in the tropics, you can make use of a reverse osmosis water filter. Pressure can be supplied to drive the water through the osmosis membrane with a hand pump if necessary – which can also be the basis of a homemade custom pump. With the proper water filters and Chlorox or iodine tablets, you can navigate the tropics without experiencing a single twinge in your gut – and spare yourself a variety of ailments, including the notorious Moctezuma's Revenge.
