<p>An apparatus for dispersing a gas in a liquid or slurry has a reaction vessel with an inner zone for the downward flow of liquid, an outer zone for the upper flow of liquid, a plurality of aerators in the outer zone and a propeller to induce downward flow in the inner zone and promote mixing and circulation of the liquid/slurry. The apparatus is particularly suitable for use in the bacterial decomposition of organic waste matter, for efficiently aerating large volumes of waste/water slurries.</p> |
