Wood-based activated carbon BAU-A is made out exclusively of birch wood charcoal by treating it with water steam at a temperature higher than 8000 C with its prior or following crushing and screening. Each manufactured batch of activated carbon is tested by Technology Department by indicators in accordance with GOST 6217-74, as well as by a number of additional indicators that are not reflected in GOST 6217-74, but important in determining quality of activated carbon used in distillery industry for sorting processing.
Wood-based activated carbons have a highly developed through-porous structure, which enhances the effect of sorting treatment by reducing channelling at long-term use. Besides wood-based activated carbon micropores are smaller in size, for example, compared with coconut activated carbon, that allows more efficient functioning at low concentrations of impurities.
This grade of activated carbon is used in processing of sorting at liquor-distillery plants.
