Abstract
Abstract The present disclosure is directed to the effective dispersion of a gaseous medium into a liquid medium, and in particular to a device which will serve this function. The device structurally is a thin channel chamber having an inlet and an outlet, at least one baffle located so as to separate the front and back walls of the chamber and of such height as to assure that its upper edge is below the outlet with its lower edge above the floor of the chamber, and at least one gas supply means located out of the vertical plane of the baffle, the height of the chamber as measured from the floor thereof to the outlet being significantly greater than the width of the chamber as measured by the distance between the front and back wall. The device finds particular application in the reduction of Biological Oxygen Demand and Total Organic Carbon in waste water streams.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
273 words
A mass transfer device comprising a thin channel member designed to receive, contain and discharge liquid, and having a forward wall disposed opposite a back wall, side walls and a floor which respectively contact and separate the forward and back walls, said chamber being provided with: i. an inlet means for providing liquid to the chamber; ii. an outlet means for providing for the discharge of the liquid and which establishes a normal liquid level in the chamber; iii. at least one substantially solid baffle disposed so as to separate and extend substantially parallel with at least one of the front and back walls, and contacting the side walls, the upper edge of the baffle being below said normal liquid level and the lower edge of the baffle being positioned so as to be located at some height above the floor level; and iv. at least one means for providing gas to the chamber and which means extends substantially the length of the chamber and is located out of the vertical plane of the baffle and on the side of the baffle which is farthest from the inlet means and at a position ranging from a height of one-half the distance of the lower edge of the baffle from the floor of the chamber to a height of about twice the distance of the lower edge of the baffle from the floor of the chamber; the chamber further characterized in that the arrangement of the respective walls are such as to provide the chamber with a height as measured from the floor to said outlet means, which is significantly greater than its width.
