This lower concentration is readily degradable by a downstream vapor phase biofilter
(VPB) and the steady nature of the feed stream will prevent the biomass in the VPB from
enduring starvation conditions between SMZ regeneration cycles. Repetitive sorption
and desorption cycles that would be expected in the field were also investigated. It was
determined that although the GAC initially lost some VOC sorption capacity, the
adsorption and desorption profiles stabilized after approximately 6 cycles indicating that
a GAC bed should be suitable for continuous operation.
In preparation for the pilot field testing of the SMZ/VPB system, design, "in-
house" construction and testing of the field system were completed during this project
period. The design of the SMZ system for the pilot test was based on previous
investigations by the PI's in Wyoming, 2002 and on analyses of the produced water at the
field site in New Mexico. The field tests are scheduled for summer, 2005.
A cost survey, feasibility of application and cost analyses were completed to
investigate the long term effectiveness of the SMZ/VPB system as a method of treating
produced water for re-use. Several factors were investigated, including: current costs to
treat and dispose of produced water, end-use water quality requirements, and state and
federal permitting requirements.
