Water filtration is big business in this day and age. And why not, given the ballooning interest in health on the part of consumers? Water being central to life, it is very important that we ingest it clean, devoid of contaminants.
There are quite a few known drinking water Filter systems. Top-graded companies, however, mainly refer two drinking water Filter systems for filtration purposes. The first is the carbon filter and the second the reverse osmosis system. The former deploys activated carbon, also variously called activated coal and activated charcoal, and happens to be a derivative of charcoal. The activated carbon is positively charged so that it attracts impurities which are charged negatively. The carbon removes chlorine, volatile organic compounds as well as sediments effectively. Moreover, it is capable of eliminating microbes with particle sizes ranging between 0.5 to 50 micrometers.
The water filtration industry mainly uses two kinds of carbon filters for drinking water Filter system: granular activated filters (also called GAC) and carbon block filters. Of the two, the latter is deemed more efficient water filter system as it eliminates a higher quantity of particles. For those who might be interested, archaeological evidence exists of ancient Egyptians using carbon filters for water as well as air purification purposes. In the ancient Hindu text, 'Sushruta Samhita' dating as far back as 2000 B.C., there is a definite reference to carbon filtration.
Sometimes filtration occurs at several levels before the product - in this case water - reaches the consumer. Some companies prefer to deploy a micron membrane for the first-stage filtering operation. Since the process does not consume much energy, it is becoming increasingly popular drinking water Filter system within the filtration industry.
A proficient adjunct to the carbon filter is the Kinetic Degradation Fluxion, more popularly known as KDF. Basically a copper-zinc formulation, the KDF uses the chemical reduction/oxidation process to eradicate mercury, lead, iron, chlorine etc. A judicious combo of KDF and GAC goes a long way in ensuring pure water to consumers.
Probably one of the most popular drinking water Filter system is the RO or reverse osmosis process which allows the water to pass through a large screen first, then through a smaller screen, and finally all the way through a carbon sieve. The reverse osmosis drinking water Filter system is so called because it employs a cross-flow system, also called backwashing, allowing the screens to continuously wash themselves sending the contaminants into the drain. All this uses up a lot water obviously and strips the healthy minerals out of the water.
