Camping Water Purifier
A camping water purifier is very necessary in modern life. It is the bane of our times that pollutants and contaminants lurk in our drinking water supplies. We have to live with this sad fact considering the burgeoning chemical usage all over the word. Even the municipal water being supplied to our homes has to be filtered to remove additives like chlorine to make for a better tasting drinking water. Camping water purifiers come in various shapes and sizes. Purifiers also remove dangerous chemicals like lead and mercury which are common urban pollutants.
The simplest form of water filter is the multilevel gravity operated filter. The filter is made up of two or three layers, each layer having a different filter to finally get clean water from the tap. The first filter can be made of cloth to stop large particles. The next level filter can be of activated carbon and the final filter before the tap is made up of a filter membrane. The final product is very clean and drinkable water.
The camping water purifier also saves one the cost of carrying expensive mineral water bottles into the wilderness. The bottles are an ecological hazard because they are not biodegradable. The exact nature of a camping water purifier depends on its real usage. Is it always going to be used outdoors? Is it going to be used eventually indoors? The indoor purifiers are available in many versions. Some employ ultra violet rays, reverse osmosis or boiling. Some make use of the three processes together. All of these use electricity and therefore are not good for the outdoors. Many successful water filters are of the many layered gravity kind. Water is poured into the top container and it eventually seeps through various filters to come out completely odourless and pollutant free at the other end of the layering.
A very common type of filtering is done with the use of chlorine tablets. An unbelievable but verified system of water purification in the outdoors called SODIS (Solar water disinfection) is done with the use of pet bottles. This are filled to the brim and then capped and preferably placed on metal roofs. The bottles are first oxygenated by swirling water inside the capped bottles. The rays of the sun which include ultra violet rays do the cleaning work. The heat generated by the hot tin roof reflecting sunlight kills any remaining bacteria. The bottles have to be kept in the sunlight for six hours on a sunny day or for two days if it is a partially cloudy day. Over centuries man has used many methods to clean water. Today we have many new ways of clearing the pollutants in water and these are available in a simple camping water purifier.
