Abstract

The invention relates to a method for treatment of biomass comprising obtaining biomass having a dry solids content of at least 3 weight-%, mixing performic acid to the biomass, and allowing performic acid to react with the biomass. The invention relates also to an arrangement comprising a mixing apparatus, such as a mixing tank with a mixer, a screw mixer or a horizontal mixer, means for feeding biomass to the mixing apparatus, a preparation unit for performic acid, and means for feeding performic acid prepared in the preparation unit to the mixing apparatus.
