Wood based activated carbon is produced from selected types of wood and sawdust. This type of carbon is produced by either steam or phosphoric acid activation. Most pores in wood based carbon are in the meso and macro pore region which is ideal for decolorization of liquids and water. Wood base carbon is primarily used in surface water and wastewater filters to remove organic impurities and to effectively remove larger molecular structures like MIB (2-Methylisoborneol) and Geosmin. Wood base phosphoric acid activation can yeild carbon with a very high surface area, ranging from 1500-2500 m 2 / g. The product is available in granular, pelletized, or powder forms.
