Abstract

A tube diffuser (10) includes an inner nonporous pipe (14) and an outer porous pipe (12). The inner nonporous pipe (14) is disposed within the outer porous pipe (12) to define a space 816) therebetween. The inner nonporous pipe (14) has at least one hole (28) through its wall to enable gas to pass from the interior into the space (16). The inner nonporous pipe (14) has a plug (30) between one of its two ends and the at least one hole (28), while the other end is connected to a source of gas, which passes from the interior of the inner nonporous pipe (14) through the at least one hole (28) into the space (16) between the two pipes, and finally through the outer porous pipe (12) as fine bubbles to aerate the liquid.
