Stabilization and Solidification Flashcards
1
Q
Purpose
A
Treatment of industrial wastes to be able to send to a landfill
-ex cannot send liquids to landfill so you can solidify them
2
Q
Stabilization process
A
-converts hazardous waste so it does not easily migrate in the environment or toxicity is reduced
3
Q
Chemical stabilization
A
addition of chemical reagents to contaminated soil to limit waste solubility and mobility
4
Q
Macroencapsulation
A
physically entrapped in larger structural matrix
5
Q
Microencapsulation
A
entrapped within the crystalline structure of the solidified matrix
6
Q
Technologies
A
- Cement
- Lime
- Soluble silicates
- Modified clays
7
Q
Stabilization Testing
A
Must test to see if it is truly stabilized
-TCLP
8
Q
TCLP
A
-Under RCRA: toxicity characteristics leaching procedure
