ABSTRACT:
A flow passage into which water-to-be-treated flows is provided with, in order from an upstream side, a deaerator as a DO eliminating device having a power variable mechanism, an oxidation device for oxidizing TOC by irradiating ultraviolet-ray, an ion eliminating device for eliminating TOC ion generated at oxidation, and a particle eliminating device. Further provided thereat are a TOC density measuring device, a DO density measuring device and a data processing device. Before the water-to-be-treated is irradiated with ultraviolet-ray in the TOC eliminating device (oxidation device and ion eliminating device), the deaerator controls a DO density in the water-to-be-treated according to a TOC density. Thus, an oxidizer of the TOC is maintained and impurity is decreased.
