We all know Activated carbon It is a good filtering and adsorption material in nature. Almost all water purifiers use activated carbon. Activated carbon is divided into granular, powder and fine Coconut shell activated carbon Three, the first two are cheap, but often filtered, the latter is more selective, 100% can be completely filtered, and the water purified by activated carbon can be directly drunk. Therefore, coconut shell activated carbon is recommended for the activated carbon used in the water purifier.

The activated carbon used in the filter element of household water purifier generally adopts coconut shell activated carbon, which can be made into granular, blocky, etc., and is often used as the post activated carbon. For water purifier Water purification activated carbon Coconut shell carbon, generally used as granular activated carbon for water purifiers, is required to be 6 mesh or 20 mesh. Generally speaking, the smaller the volume, the larger the overall surface area.

The cleaning of activated carbon is generally divided into acid cleaning and non acid cleaning. There are few domestic requirements for acid cleaning, and the international basic requirements for acid cleaning activated carbon. In China, it is good to have acid cleaning, and the amount of powder produced after acid cleaning is relatively small. But at present, many small factories rarely follow the requirements when filling cans, and often mix non acid cleaning, so we often encounter, The water powder or black water from the post activated carbon is very serious.
