Specifically, the parallel-phase fluid section is arranged such that the second additive, such as hydrochloric acid, from the second additive injection section naturally diffuses in the solution from the reactor 21 by virtue of its own diffusion force. The parallel-phase fluid part may be a section of pipeline without any obstacles inside. In this way, the high-concentration stock solution of additives can be naturally diffused first and the concentration can be reduced, thereby preventing useless reactions.
