PURPOSE:To permit dissolution of a large amt. of O2 in water by providing an air feeder having many small holes for blowing air to a downstream side of a water stream before a water stream generator, and communicating a compressed air source to said air feeder. CONSTITUTION:Water stream is generated by revolving a vane 3 of a water stream generator 1. Air is blown out from many small holes 8a of an air feeder 8 communicated to a compressed air source 9 to the water stream. The air is swallowed and mixed in the whirling water stream in the form of fine particles. A mixed stream AF is separated by the effect of waves JFW of the whirling water stream from the mixed stream AF of the air with the water, and the air in the separated AF is allowed to be entangled in the water. Thus, a large amt. of O2 is dissolved in the water. |
