<p>A tube diffuser for use in a fine bubble diffuser system to disperse fine bubbles of air or oxygen into a liquid for purposes of aeration, such as into a body of wastewater, includes an inner nonporous pipe and an outer porous pipe. The inner nonporous pipe is disposed within the outer porous tube to define a space between them. The inner nonporous pipe has at least one hole passing from its interior through its wall to enable air or oxygen to pass from the interior into the space between the inner nonporous pipe and the outer porous pipe. The inner nonporous pipe is plugged between one of its two ends and the at least one hole, while the other end is connected to a source of air or oxygen, which passes from the interior of the inner nonporous pipe through the at least one hole into the space between the two pipes, and finally through the outer porous pipe as fine bubbles to aerate the liquid.</p> |
