| Advantages
of CBR System |
 |
Adsorbs
organic contaminants, color, Adsorb VOC and odor |
|
Improves： |
| |
˙Effluent
bioassay (reduces/eliminates effluent toxicity)
˙Sludge
settling & thickening characteristics
˙Sludge
de-waterablity
˙Hydraulic

| PAC
vs GAC Size |
|
PAC
is micron size vs mm size for GAC |
|
PAC
has higher rate of adsorption |
|
PAC
has more available surface area than GAC |
|
PAC
can be regenerated as slurry (using Wet Air Oxidation),
GAC cannotPAC can be added to existing activated sludge
systems, GAC cannotPAC is about 1/2 the cost of GAC |
