A new air/oxygen bubbling unit for aerating water media in large-scale aquaculture experiments

The hose adaptor (Fig. 2, 1), a tube with serrations outside for holding the hose from the air|oxygen source, is attached to the main body of the bubbling unit by means of a tightening nut (2). The central adaptor (3), which is the main body of the unit, is a cylindrical hollow structure. One end of this adaptor is threaded and is fitted to the hose adaptor, and the other end, with a protruding M-12 threaded portion, is fixed to the grinding wheel (4)
