Active carbon filter works by carbon bed. The active carbon particles forming the carbon bed, have great amount of pores and large surface, with great absorbing power. Water flows through the carbon bed, with the organic matter absorbed effectively by the active carbon. The amorphous substance on the surface of the active carbon. The amorphous substance on the surface of the active carbon has oxygen-containing group, which effectively absorbs organic pollution material from the water flowing through the carbon bed. Active carbon filter is a normal water treatment equipment, as the pre-process of the water treatment to remove salt. It can ensure the service life of the later equipment , improving the outputting water quality, stop pollution, especially to stop the free state oxygen pollution of later anti-filtration film and ion exchanging resin.
