AirRaider: A Powerful Tool in the Fight Against Groundwater Contamination

In the field of environmental and water treatment, the term "AirRaider" often refers to a powerful technology used to combat groundwater contamination. This technology utilizes a system known as "pump and treat," designed to remove contaminants from the ground and treat them before releasing them back into the environment.

One prominent example of an AirRaider system is the MTBE pump and treat system by Product Level Control, Inc. This system focuses specifically on removing methyl tertiary butyl ether (MTBE), a common gasoline additive, from groundwater.

What is MTBE Contamination and Why is it a Concern?

MTBE, despite its widespread use in gasoline, is a significant environmental hazard. It easily dissolves in water and is highly mobile in the subsurface, making it a major threat to groundwater resources. Contamination can occur due to spills, leaks, and improper disposal of gasoline-related materials. MTBE is particularly concerning because it:

  • Is difficult to remove from water. Traditional treatment methods are often ineffective at removing MTBE.
  • Has a strong odor and taste. Even low concentrations can make drinking water unpleasant to consume.
  • Can pose potential health risks. While long-term health effects from low-level MTBE exposure are still under investigation, the chemical is classified as a possible human carcinogen.

The AirRaider MTBE Pump and Treat System: A Comprehensive Solution

Product Level Control, Inc.'s AirRaider system offers a comprehensive solution for MTBE groundwater contamination. The system employs a multi-step approach:

  1. Extraction: A series of wells are installed to extract contaminated groundwater from the subsurface.
  2. Air Stripping: The extracted water is then passed through an air stripping tower. This process utilizes a stream of air to remove the volatile MTBE from the water, effectively transferring the contaminant to the air stream.
  3. Air Treatment: The air stream containing the MTBE is then passed through a dedicated air treatment system. This system utilizes specialized adsorbent media to capture and remove the MTBE, preventing its release into the atmosphere.
  4. Treated Water Discharge: The treated water, now free from MTBE, is either discharged back into the environment or utilized for other purposes, depending on local regulations and water quality standards.

Benefits of the AirRaider System:

  • High Efficiency: The system is designed to effectively remove MTBE from contaminated groundwater, achieving significant reductions in contaminant levels.
  • Environmentally Friendly: The air treatment system prevents the release of MTBE into the atmosphere, minimizing further environmental impacts.
  • Reliable and Sustainable: The system is engineered for long-term operation, providing a sustainable solution for MTBE contamination.
  • Cost-Effective: The AirRaider system offers a cost-effective alternative to other MTBE removal technologies, particularly when dealing with large-scale contamination.

Conclusion:

The AirRaider MTBE pump and treat system by Product Level Control, Inc. represents a significant advancement in the field of groundwater remediation. It offers a powerful and comprehensive solution for removing MTBE from contaminated groundwater, protecting valuable water resources and minimizing environmental risks. As we continue to grapple with the challenges of groundwater contamination, innovative technologies like AirRaider will play a crucial role in ensuring the safety and sustainability of our water resources.
