<p>The method involves generating water current in form of recirculation loop inside a tank (1) by localized insufflation of pressurized air in water (E). Top and bottom ramps (4, 2) comprising portions (21, 41) with openings (O) are used. A pipe (5) is used to connect the ramps. A supply tube and a box (3) supply and distribute pressurized air into the pipe. The box is placed opposite to and at remote from the base such that a portion of water entering into the bottom ramp is conveyed to top of the pipe by current generated by air and redistributed into the tank via the openings.</p> |
