Mott spargers introduce gases into liquids through thousands of tiny pores, creating bubbles far smaller and more numerous than with drilled pipe and other sparging methods. The result is greater gas/liquid contact area, which reduces the time and volume required to dissolve gas into liquid.

With thousands of pores over the surface, large volumes of gas can be passed with very high specific area. For example, with equal volumes of gas, 1mm bubbles would have 6.35 times more gas/liquid contact surface area than 6.35mm (1/4") bubbles.
