Wood-based activated carbon BAU-CP fraction 3-6 mm is made out exclusively of birch wood charcoal by treating with water steam at a temperature higher than 8000C with its prior or following crushing and screening. Each manufactured batch of activated carbon is tested by Technology Department by for activated carbon compliance with TU 20.14.72-005-06343907-2017, as well as by a number of additional indicators that are not included in this specification, but important in determining the quality of activated carbon used in distillery industry for sorting processing.
Wood-based activated carbons are characterized by a highly developed through-porous structure, which enhances effect of sorting treatment by reducing channelling at long-term use, and also wood activated carbon micropores are smaller in size, for example, compared with coconut activated carbon, which allows their more efficient functioning at low concentrations of impurities. Activated wood-based carbon BAU-CP 3-6 mm fraction is low in dust content and characterized by a high strength in operating process in column at alcohol-water mixture processing.
This grade of activated carbon is used in sorting processing in liquor-distillery production.
