PRM manufacturer’s air sparging systems for the remediation of soil or groundwater and these systems can be used for petroleum and chlorinated contamination. Air sparging technology injects pressurized air into the soil or ground water for contaminate volatilization, the process also promotes biodegradation. Air Sparging systems are often used in conjunction with SVE systems that create a negative pressure in the formation to draw the contaminated saturated air out of the formation for further treatment. When designing a dual system it is important to have the proper controls to allow the SEV and Air Sparge to properly interact. Air sparging is typically more effective in sandy-silty soils.       

Air sparge systems typically employ an air compressor, rotary vane or positive displacement blower to pressurize ambient air, a heat exchanger to reduce the temperature of the pressurized air stream, a manifold to distribute the pressurized air to the injection wells and the control panel. These systems can be skid mounted of incorporated into a trailer or building. Positive displacement blowers are typically selected for moderate to high flow rates and low to moderate pressures. Rotary vane compressors are generally selected for lower flow rates and moderate to low pressure. Rotary screw compressors are a better choice for higher flow and pressures.
Considerations in the design of an air sparge system include required air flow rate, air pressure, soil matrix, the number of injection wells and the well design. Consult with the PRM design team for assistance in choosing the proper equipment for your site application
