Ambersorb® 563 Adsorbent
Roy F. Weston, Inc.
ABSTRACT
The Ambersorb® 563 is a regenerable adsorbent
that treats groundwater contaminated with hazardous organics. Ambersorb® 563
adsorbent has 5 to 10 times the capacity of granular activated carbon (GAC)
for low concentrations of volatile organic compounds (VOCs ) and can be regenerated
on site using steam. Condensed contaminants are recovered through phase separation.
Because Ambersorb® 563 adsorbent has a higher capacity for VOCs than GAC (at
low concentrations), the process can operate for significantly longer service
times before regeneration is required and can operate at higher flow rate loadings.
Ambersorb® 563 adsorbent are hard, nondusting, spherical beads with excellent
physical integrity, eliminating handling problems typically associated with
GAC. Ambersorb® 563 adsorbent is not prone to bacterial fouling and has extremely
low ash levels. It is applicable to any water stream containing contaminants
treated with GAC, such as 1,2-dichloroethane, 1,1,1-trichloroethane, tetrachloroethene,
vinyl chloride, xylene, toluene, and other VOCs. The technology was evaluated
at the Former Pease Air Force Base in New Hampshire. The groundwater was contaminated
with vinyle chloride, 1,1-dichloroethene, and trichloroethene. The effluent
from the Ambersorb® system consistently met drinking water standards.
