Oil separator and Structural soil (Swe: Skelettjord) implemented as new treatment facilities. Addition of biochar (Swe: biokol) to the biofilter box.

Oil separator and Structural soil have been implemented as new treatment facilities in StormTac Web.

Addition of biochar to the biofilter box results in added reduction efficiencies for e.g. biofilters, structural soil and macadam ditches.

These implementations are a result of literature studies.
