Water Filter has a long history as a way to purify water, ranging from 2000 BC in ancient Egypt. Filtration has evolved from a simple Hippocratic sleeve of ancient Greece, made of fabric, the complex solid carbon block water filters and multimedia on the market. Filtering water is now the main method of purifying water, removing contaminants better than other techniques.
The process is:
Filtering process is a type of filter media, where the water flows. This filter media blocks the passage of contaminants through physical obstruction, chemical adsorption, or a combination of both processes. Development of filter media materials vary greatly, but the most effective media is made of carbon or carbon combined with other elements. Modern filtration technology allows water filters to remove pollutants and more through a process of chemical adsorption. In the adsorption process, contaminants are encouraged to change their relationship with water and chemical molecules adhere to the filter media. In general, the water passes through several stages of filtering to ensure that each filter will remove the actual number of pollutants. The water is usually passed through a water filter at relatively low speeds, to ensure sufficient contact time with filter. When water passes through the necessary stages of filtration, is seen as pure drinking water free of contamination.
