Abstract

This invention relates to remediation systems, and more particularly to remediation systems for water, soil, and sediment bodies using thin-layer coated microbubbles.

Claims

1-45. -45. canceled.

46. An aerosol head comprising:

a reservoir of liquid;

a tube supply with compressed air;

a mixing chamber where the liquid is drawn into the flowing gas; and

a spray head which controls the particle size and distribution of the aerosols.

47. The aerosol head of claim 46, further comprising:

a reservoir of liquid and microfine particles mixture.

48. The aerosol head of claim 46, further comprising:

a siphon tube.

49. The aerosol head of claim 46, further comprising:

a compression fitting which directs the aerosol flow into the air/ozone gas stream.

50. The aerosol head of claim 46, further comprising:

a connecting tubing comprising;

PTFE tubing ⅜

″

to ½

″

in diameter and

polyvinyl chloride tubing ½

″

to 1″

in diameter with viton o-ring seals and threaded 5 ft. sections.

51. The aerosol head of claim 46, further comprising:

a receiving microporous diffuser having a 0.5-200 micron high-density polyethylene microporous material and a diameter of 2″

to ¾
