Attempted biofiltration of reduced sulphur compounds from a pulp and paper mill in Northern Sweden
Abstract The objective of this study was to identify the reduced sulphur compounds (RSCs) present in waste gas from a specific deaerator at a pulp and paper mill in northern Sweden, and to investigate the feasibility of a multi‐stage biofilter to treat these compounds in an industrial setting. Two f...
