Integrated Air Sparge System at a Space Launch Center
MAE2 was selected as the most responsive bidder in a competitive bid process to build and start up an integrated Air Sparge system for a former maintenance building at a space launch center.
The system was designed to remediate a solvent plume around the former building site. There are 213 wells spread across the site in order to create high air flow and radius of influence across the plume. The system design includes programmable timers that allow the user to rotate air delivery through the different site areas as desired. There are 10 sparge zones on the site, and each can be programmed for specific on off times to optimize remediation.
The project includes remote operation and monitoring so that the performance can be viewed and adjusted as required. The completed system includes a 125 HP variable speed rotary screw compressor capable of providing up to 648 CFM. The compressor automatically adjusts to provide only the air demand needed at any given moment which saves electricity and prolongs the life of the equipment. The system controls display and log temperature, pressure and CFM flow for the compressor and well field areas. The set points and operation timers can be adjusted remotely by phone or computer to maintain optimum efficiency.
The system was installed in a utility trailer custom designed to handle the size and weight of the compressor. Custom duct-work for compressor the intake and exhaust and split unit air conditioners for climate control were designed to keep the interior of the trailer at the low temperature and low humidity that the compressor requires for proper operation.
The system effectiveness was evident as the influence on the water table and in the monitoring wells was immediate.
