Abstract

1,111,354. Surface aeration, agitation and circulation of liquid. PUMPANLAGGNINGAR A.B. 24 June, 1966 [5 July, 1965], No. 28283/66. Heading B1C. A rotatable surface aerator for the activated sludge process comprises blades 4 (which may be generally radial and vertical) having an annular inverted frusto-conical shroud 3 from the inner periphery of which extends upwardly an air intake 6; a downwardly extending liquid intake 5 is attached to the inner edges of the blades. In operation the outer edge of the shroud 3 is immersed in the liquid and aerated liquid is ejected from beneath it.
