Abstract: The proposed invention relates to a method for fluid treatment of wood comprising the steps of placing the wood in an airtight tank, evacuating the airtight tank to establish a vacuum environment for the wood, applying a fluid to the wood. Additionally, the method may further comprise the subsequent step of pressurizing the airtight tank to establish a pressurized environment for the wood. The method may further comprise the subsequent step of subjecting the wood to a subsequent heating, and/or the prior step of subjecting the wood to a prior heating by electromagnetic radiation through one or more electrodes.

Abstract: A method for treating wood by a treatment liquid is put forward. The method comprising the steps of: providing a container to hold the wood and the treatment liquid, placing the wood m the container, providing a electrode in the container for subjecting the wood to radio-emission, and providing a specific volume of the treatment liquid Ln the container for at least partially covering the wood and to at feast partially covering the electrode below the surface of the treatment liquid. Further, the method comprises the steps of providing a first flow in the container of the treatment liquid towards and from the wood at feast partially covered by the treatment liquid for removing at least some of the treatment liquid at the wood, and subjecting the wood at teas! partially covered by the treatment liquid to an exposure by radio-emission from the electrode for Increasing the temperature of the wood.
