Plasma is generated in a gas phase in a processing tub to produce a reforming component, the produced reforming component is dissolved in a liquid and is dispersed in the liquid to produce a reforming liquid, the produced reforming liquid is discharged from the processing tub to be stored in the storage tub, and gas is supplied from a gas supplier into the reforming liquid in the storage tub. The supplied gas has a bubble shape, comes into contact with the reforming liquid stored in the storage tub, and is deodorized.

A compact cylindrical vacuum chamber made from a dielectric ceramic or glass wrapped with a cylindrical electrode connected to an RF source make a hollow cathode RF plasma source. The dielectric cylinder is used as the vacuum container with the conductive electrode outside the vacuum region to excite plasma inside. A gas is supplied by a gas source at low flow on one end of the cylinder and after being excited exhausts into a connected vacuum chamber carrying excited metastables and radicals. RF power is applied to the electrode to excite the plasma via the hollow cathode effect. This remote RF plasma source can be used to create ions, electrons, excited metastables, and atomic radicals for use downstream depending on choices of gas, pressure, flow rates, RF power and frequency, and extraction electrodes.
