Wastewater Mercury Removal?
Wastewater Mercury Removal?
(OP)
I am looking for a process to remove mercury chloride from wastewater streams generated from the treatment of flue gas at a coal fired plant.
Are there any known processes and should the mercury in this wasterwater stream even be an issue?
I don't have any concentration data and am looking at issues passed to me by management that may arise in the forseeable future.
Thanks for the help.

To remove mercury, sulfide precipitation is a reliable technology that is capable of meeting extremely low discharge requirements. Siemens has a FGD treatment scheme presented in the link below that utilizes sulfide precipitation.
There are other mercury technologies such as resins, carbon, etc. My understanding is that sulfide precipitation is probably the best technology.
Bench and pilot testing will be critical for the success of an application.

I agree with bimr that bench and pilot testing is critical for success in this type of application.

One of the problems with wastewater treatment is disposal of the residual materials. This is less of a problem with sulfides as the sulfides are relatively stable. Most of the metal ores found in nature are actually in the sulfide form.
