The addition stage is arranged to receive the de-watered biomass material, wherein the addition stage includes inlets for adding acid containing solution into the addition stage. A reactor stage arranged to receive the biomass material treated in the addition stage and to perform a pre-hydrolysis process to the biomass material. A filtrate feeding arrangement is arranged to feed liquid from the filtrate tank to the reactor stage.
