Directional microporous diffuser and directional sparging

摘要

A method for treating contaminants includes emitting plural streams of a fluid into a soil formation with the streams having different radii of influences in different directions. A directional microporous diffuser directionally emits microbubbles. Solenoid controlled valves control fluid or air distribution to inlets to provide directional control of bubble emanation.

主权项

1. A directional microporous diffuser comprising:
a first elongated member including at least one sidewall having a plurality of microscopic openings, said sidewall defining an interior hollow portion of said member; a second elongated member having a second sidewall having a plurality of microscopic openings, said second elongated member being disposed through the interior hollow portion of said first elongated member; two or more first partitioning members disposed inside and along a length of the first elongated member to provide a first plurality of isolated chambers; a second partitioning member disposed inside and along a length of the second elongated member to provide a second plurality of isolated chambers; an end cap to seal a first end of the directional microporous diffuser; and an inlet cap disposed at a second end of the directional microporous diffuser for receiving inlet fittings.
