Integrated Remediation Systems
Aerobic Bioremediation Systems
Aerobic Bioremediation Systems are designed to deliver high volumes of dissolved oxygen and hydrocarbon degrading bacteria and nutrients to treat hydrocarbon contaminated sites. The systems provide consistent recirculation of oxygen-rich, nutrient-rich water to provide the critical requirements needed for successful in situ bioremediation. This recirculation provides the appropriate oxygen and nutrient volumes required to degrade the contaminant mass and continuous movement of the amendments throughout the site to provide maximum contact with the contaminated soils. These units can be stand alone or fully integrated into an existing or new Multi Phase Extraction System or Pump and Treat System.
Vapor Liquid Separators
Regardless of the vacuum blower chosen, a vapor liquid separator should always be installed inline prior to the blower to capture extracted liquid and minimize on liquid carry over to the blower inlet.
Vapor Liquid Separators are sized based on air flow rates and retention time. At a minimum the VLS should include an inlet filter, ambient air dilution valve with control valve, discharge demister element, discharge pump with controls, and instrumentation – vacuum / pressure / temperature gauges.

Stackable Tray Air Strippers
The unique configuration consists of a series of integrally-molded shell/tray modules. The multiple sieve tray design uses forced-draft air bubble generation to provide rapid, effective VOC removal (up to 99%).
Every element of the heavy-duty HDPE construction has been engineered for durable, reliable performance with a multi-step positive seal against leakage.
Models are sized and priced to be the most economical choice for many low to moderate flow cleanup applications (up to 40 GPM-Poly Construction). Low capital expense and low O and M requirements make the difference.
Rotary Screw Compressors
Rotary Screw compressors are available with a large range of flows from 4-250 HP and air flow rates from 10 to 1500 cfm and larger. Most screw compressors have pressure ranges from 100-150 psi. Rotary screw compressors require frequent maintenance ranging from oil changes, filter changes and condensate management.
Rotary Claw Compressors
Rotary Claw compressors are available with flow rates from 65-350 cfm and pressures ranging from 15-30 psi. Claw compressors require little to no maintenance. Standard gear oil changes are 20,000 hours. Inlet filters may require more frequent changes based on the air quality of the environment in which installed.

Rotary Vane Compressors
Rotary Vane compressors are available from very low to moderate air flows typically 3-325 cfm with pressures from 15-25 psi. Rotary Vane compressors require changing of filters and vanes on a regular basis.
ChemOx, Peroxide and Surfactant Injection
Chemicals are often injected into the subsurface in order to oxidize (reduce) groundwater and soil contaminants. Surfactants force soil contamination to unbind from the soils which can greatly increase the volume of contaminants removed by your pumping system. MAE2 can help you select the chemicals, surfactants, nutrients and equipment for effective site injection events.
Bio Augmentation
Bio Augmentation (biologically enhanced recirculation) involves the injection and recirculation of bacteria, nutrients or substrates to create an active, balanced environment in the subsurface that biologically degrades and eliminates the contamination. MAE2 can help design fully automated and manual recirculation equipment for enhanced Bio remediation for gasoline and chlorinated solvent sites.
Metals Precipitation Systems
Dissolved and particulate metals in water streams can create maintenance headaches and downtime. Metals precipitation systems are designed to manage or prevent these costly problems. MAE2 can recommend chemical and mechanical options for removing metals from solution to meet discharge requirements or reduce fouling problems.
SVE Enhanced Pump and Treat Systems
Soil Vapor Extraction Enhanced Pump and Treat Systems technology is the use of vacuum systems and/or sparging systems along with downwell pumps to increase the removal rate for contaminated groundwater and soil vapor. The higher vacuum increases the groundwater gradient allowing downwell pumps to remove the groundwater at a higher pumping rate. MAE2’s design team can help you select the best equipment and treatment components for your site needs.
Typical SVE systems include TEFC or XP motor, moisture separator with high level switch, inlet filter and a pre wired, pretested, custom NEMA IV control panel. Also gauges, flow indicators, temperature indicators and transmitters that can be specified per your application.
All components can be fully integrated and pre wired on a steel skid with optional custom sound attenuating enclosure or integrated with new or existing Groundwater Systems.
