Why Reactivation?
When your media needs to be changed out, there are multiple ways to handle the waste material. Landfilling and/or incineration are commonly used but are not environmentally friendly. Tetrasolv is committed to being “green” and highly recommend reducing emissions and reactivate spent carbon.
Reactivation Benefits
- Meets environmental need to minimize waste
- Reduces CO2 emissions
- Limits the use of the world’s resources
- Reduces the cost of activated carbon usage
What Is Reactivation?
Sometimes also called regeneration, reactivation is a thermal desorption process that volatilizes and removes the desorbed components from spent activated carbon, allowing it to be reused. The first step is Drying, where water and low boiling volatiles are removed. Then, Devolatization and Carbonization take place to remove higher boiling volatiles, causing the surface of the carbon to be carbonized. In the last half of the kiln, steam in introduced to Reactivate and open the pores on the carbon. The resulting reactivated carbon will have the majority of its original adsorptive capacity and can be used in most filtration applications.
