<p>Polluted waste waters are introduced into a tank (1, 100) in which a number of cavitation oxygenizers (5, 6, 11) are installed close and parallel to the bottom of the tank and divided into three types, one (5) that expels re-circulated water and air, a second (6) that expels water, air and sludge and foam sucked in from the upper region of the tank, both these two types suited to causing turbulence (F1, F2-F3, F4) of the polluted water within the tank, and a third (11) suited to cause a further turbulent motion of the polluted water.</p> |
