Abstract
A method and related apparatus for monitoring and eliminating gas build-up in an anion exchange column comprised of an anion exchange material placed within a vessel and a liquid layer comprising water contaminated by at least antimony passing through said vessel, which method comprises maintaining said anion exchange material within said liquid layer by allowing gases produced by a reaction of said liquid layer with said anion exchange material to be released from said anion exchange vessel though a valve or other gas release mechanism.
Claims34
A method for removing antimony from waste water comprising the steps of:
- passing a contaminated liquid through an anion exchange media placed within an anion exchange column;
- monitoring said anion exchange column for gas build-up;
- and
- removing built-up gas from said anion exchange column.
An anion exchange column for removing antimony from waste water comprising:
- a vessel having a monitoring mechanism for monitoring a level of an interface between said waste water and gas-build up in said anion exchange column;
- an intake port for receiving waste water;
- an anion exchange material;
- and
- an output port.
An anion exchange column for removing antimony from waste water comprising:
- a vessel;
- an input port for receiving waste water;
- an anion exchange bed immersed with said waste water;
- and
- an output port for removing said waste water after processing,
- wherein said vessel is configured to hold a volume of waste water which is at least two times the volume of said anion exchange material in said vessel.
