Iron Hydroxide Sludge

["Andrea K. Farrell" <afarrell@state.de.us>]

Hi all,

I am working with a company which produces ink.  They have a process 
byproduct which is an iron hydroxide sludge.  At this point, there isn't a 
way to reduce the byproduct, so I am curious if anyone knows any potential 
uses for the material. It contains:

Iron Hydroxide 80-90%
Dirt  0-1%
Sodium Chloride  9-15%
Water 10-20%

(I know, these don't quite add up, but they're what I've got)

Any thoughts would be appreciated.
