Abstract: A gas sparger produces an intermittent flow of bubbles even if provided with a continuous gas flow. The sparger has a housing to collect a pocket of gas and a conduit to release some of the gas from the pocket when the pocket reaches a sufficient size. Optionally, a cover over an outlet from the conduit may break up or distribute the released gas. A large sparger for use with a commercial membrane module can comprise a plurality of smaller units.

Abstract: A gas delivery device includes a manifold and a plurality of channels. The manifold is adapted to be connected to a source of a pressurized gas. Each of the plurality of channels is in fluid communication with the manifold through a distinct associated port. Each of the plurality of channels has a generally open bottom.
