Clean water, pure water is no longer available. Safe drinking water is fast becoming a myth. Indeed, more than a billion of the world's population does not have enough drinking water at all.Water drawn for human consumption from wells, bore wells, lakes and rivers can no longer be considered absolutely safe. Water today needs to be rid of contaminants to produce pure water for human consumption or for industrial use. The villains of the water story are parasites ( such as Giardia or Cryptosporidium), bacteria, algae, viruses, fungi, minerals including toxic metals such as lead, copper etc., and man-made chemical pollutants.Water FiltersWater is used as a cleaning agent in our daily lives. It is also vested with a spiritual symbolism.
Baptism with water or bathing in River Ganges is supposed to wash away one's sins. But if water gets polluted, how shall we get it purified? The answer is filtration!We have come a long way from the days of Hippocrates of 4th century BCE who introduced the method of putting boiled water through a cloth bag which is now called Hippocrates's sleeve.Water filters employ a variety of processes, often in combination with one another:?Oxidation: Using chemicals like chlorine and chlorine dioxide effective against microorganisms, combined with sand bed filter?Boiling - kills microorganisms, an age old method?Ozone - A molecule of oxygen, broad-spectrum disinfectant, effective against protozoa that produce cysts, and most other pathogens.UV radiation - eliminates pathogenic bacteria causing cholera, typhoid, and salmonella dysentery?Reverse osmosis - use of a membrane to keep out salts, insoluble ions and concentrations?Carbon filtering - removes many compounds including toxic ones?Distillation - purifies water 99%, but tasteless and addition of minerals improves taste?Ion Exchange -removes heavy metal content and softens hard water?Micro filtration through ceramic cartridges - even the minutest contaminants are denied passage through these filtersChoice of Water FiltersBefore you choose your water filter, you should get the water analysed and determine the filtration processes called for, the output and cost effectiveness.
You have a good variety of water filters to choose from.?Filters: Aquasana produces water filters for kitchens and for showers as well. Its household model employs four stages of filtration. Periodic replacement of filters is advised.?Distillers: You can choose from among Water Wizard, Pure Magic and Waterwise 7000 series. There is also a non-electric model (1600). All these distillers come with a supply of trace minerals which lend taste to the water after distillation.?Ionizers: For alkaline water - Bion Tech Digital BTM -3000N turns dead tap water into vibrant water. Bion Tech BTM-200N uses silver impregnated carbon filtration before ionization. Bion Tech 500 incorporates twelve stages of filtration. Bion Tech BTM-105 U takes care of acidic water as well. ?Pi Water: The Neos Pi Water Filter incorporates an eight stage filtering system which also invests water with taste and vibrancy after filtering out all kinds of contaminants. ConclusionIn urban areas, municipal authorities operate water purification plants and supply protected water to their populations. But where finer standards are prescribed for domestic or industrial purposes, water filters have come to play an important ancillary role. In the rural areas and the outback, they will play the primary role in ensuring supply of safe and palatable water for domestic use.The Age of Aquarius is at hand. May the gentleman with the down turned pitcher of flowing water pour wisdom into the hearts of men and inspire them to preserve in all its purity the life giving gift of Nature!For more information visit
