| Short description: |
The purpose of the demonstration was to evaluate a complete
perchlorate ion exchange process for groundwater that included a
unique, regenerable, perchlorate-selective ion exchange resin;
an efficient regeneration technique that greatly minimized waste
volume; methods for treating regeneration waste from this
process that would reduce cost by enabling discharge or reuse;
and to demonstrate a new perchlorate field monitor with ppb
detection. In order to validate the performance and economics of
the proposed processes compared to current perchlorate treatment
processes, the following objectives were proposed: Demonstrate
perchlorate removal in groundwater from >50 ppb to ¡Ü 5 ppb
with a regenerable, perchlorate-selective ion exchange process.
Demonstrate an efficient regeneration technique of the
perchlorate-selective ion exchange resin. Regenerant volume
should be < 0.1% of treated groundwater stream. Demonstrate
removal or destruction of perchlorate (¡Ü 5 ppb) in the
regenerant stream enabling discharge or reuse of the regenerant
stream. Demonstrate the performance of a perchlorate field
monitor capable of on-line, real-time perchlorate analysis with
a minimum detection limit of 1 ppb
