Method for the Removal of at Least One Contaminant from an Aqueous Liquor or a Gas
17 Mar 22
A method for the removal of at least one contaminant from an aqueous liquor or a gas, comprising: preparing a solution or slurry of a solid alkali reagent by supplying a solid alkali reagent into a pre-wetting chamber via a feed pipe; supplying a liquid via two or more liquid sidestreams, each through a liquid inlet positioned on a side wall of the chamber to allow the liquid sidestreams to wash an internal wall of a frusto-conical section of the chamber and flow, preferably tangentially onto the internal wall in a downward spiraling manner thereby forming a vortex, towards a fluid outlet of the chamber and to further wet the solid alkali reagent with the supplied liquid thereby forming a pre-wetted reagent; and flowing a stream though a conduit, thereby creating a suction by the eductor to draw the pre-wetted reagent out of the chamber fluid outlet and mixing it with the stream to form a slurry or solution; and directing the slurry or solution exiting the eductor to an aqueous liquor or gas treatment unit, removing at least a portion of the contaminant from the aqueous liquor or gas in the treatment unit.
