Is household water filter useful? What's the principle of household tap water filter? What's the principle?
Compound: when a process is difficult to remove harmful substances in the water, with two or more than two kinds of process is complex. Such as activated carbon adsorption, ultraviolet sterilization, activated carbon adsorption, reverse osmosis, activated carbon adsorption, micro filtration (ultra filtration), polypropylene fiber, active carbon, Tim micro filtration (ultra filtration).
Reverse osmosis: a separation technique, this method for pressure water through the synthesis of membrane, membrane allows only pure water through, and pollutants are excluded. R/O reverse osmosis technology adopted by the US government and NASA spent hundreds of millions of dollars, in order to solve the astronauts on the moon of the drinking water problem of high-tech achievements after years of efforts carefully developed. The cost is high, suitable for poor water quality in the area.
Activated carbon: more commonly used, the use of essential, coal, shell (nuclear) and other carbon containing substances by chemical or physical activation law
