<p>PURPOSE:To enable the stable removal of corrosive free carbonic acid by enhancing the removal effect of carbonic acid and increasing dissolved oxygen and suppressing the irregularity of the removal effect, to reduce initial cost and running cost by achieving the compactification and structural simplification of apparatus equipment and to facilitate maintenance and control in conformity with the increase and decrease of the amt. and pressure of water to be treated. CONSTITUTION:Water W to be treated is dividedly sent to the pipelines 20, 21 of a water sending pipe 2 under pressure by the operation of a pump to be introduced into the base part 30 of a nozzle 3 as a high pressure and high speed water stream from two inlets 3A, 3B parallel to the tangential line of the base part 30 and the introduced high pressure and high speed water stream is injected from the outlet 3C of the nozzle 3 while swirling so as to have a high tangential speed component and converted into an annular cone shaped swirl 6 to be allowed to fall.</p> |
