Long Term Rental System at a rural GA Gas Station
Rental Systems have often become a preferred option for fund reimbursed cleanup sites.
Renting a system offers flexibility to adapt to site or funding changes. This offers regulators more control over site operations and provides a more predictable reimbursement cost. Also, since rental systems are already assembled, the time from purchase order to start up is much quicker.
The consultant has worked with MAE2 to provide several rental systems for site remediation. The consultant recommended a multi-phase groundwater pump and treat remediation system that incorporated down well groundwater pumps and high vacuum DPE (Dual Phase Extraction) in order to remove the free product and lower the dissolved phase gasoline concentrations.
MAE2 provided a high vacuum rotary claw pump system and QED pneumatic auto pumps to dewater the wells and enhance the vacuum influence. The rotary claw vacuum pump was chosen to allow the system flexibility to operate at a wide range of vacuum levels. The flexibility allows the system to operate at low vacuum to help slurp the free product in the wells while pumping at a low rate to maximize the free product recovery. The vacuum can also be increased to maximize dewatering and dissolved phase recovery.
The 9 pneumatic auto pumps operate on demand with a 10 HP reciprocating air compressor providing the air supply needed for pumping. The Groundwater Treatment system consists of an air water separator, an oil water separator to remove free product and a poly stackable tray stripper to remove the dissolved phase gasoline and then pumped through bag filters plumbed in series and two high pressure steel carbon vessels for final treatment before discharge. The OWS pump and Air Stripper pump are centrifugal transfer pumps. An enclosed steel frame utility trailer maximizes flexibility and mobility.
The regulatory agency requires consistent run time for all approved systems. The system provides run time hours, vacuum trends, and water flow totals recorded through the PLC control panel. The cellular connection allows full system control and data through easy-to-use web browser access. The instant alarm notification and remote control allows the consultant to immediately respond to any changing site conditions and maximize system run time.

Leachate and Condensate Pumping Systems
If you need to dewater, move leachate, or pump contaminated groundwater, MAE2 has what you need. Choose from a wide range of electric and pneumatic pumps for any application.
Centrifugal Transfer Pump Systems
Centrifugal pump systems are used to transfer liquids from sumps, pits, tanks and transfer stations.
These pumps come in a variety of horsepower and typically require 208-230/460 3 phase power. These pumps can be designed for low flow low head or high flow high head scenarios. Typical flow rates are 5-200 GPM with TDH ranges from 5-200. MAE2 can integrate centrifugal pumps as prepackages systems using common skid base, inlet and outlet pipe and fittings, instrumentation and local or remote control packages.
Pneumatic Pumping Systems
Pneumatic Free Product Recovery and Total Fluids Pumping Systems
Pneumatic submersible pumps, a type of downwell pump, are used to extract contaminated groundwater, leachate and free phase LNAPL and DNAPL. Each pump system uses air to displace the liquid and are safe in explosive hazardous locations. Pneumatic pump systems provide low to moderate flow rates typically from .5-8 GPM. MAE2 can provide turnkey pneumatic systems coupled with compressor, solenoids, level control, product drums, oil water separators and treatment packages.
Pneumatic Pump Water Treatment System
Electric Submersible Pumps
Electric submersible pumps,a type of downwell pump, are used to extracted groundwater and can be designed for low and high flow scenarios.
MAE2 can provide turnkey submersible pump packages with down well tubing, electrical cable, well head assemblies, instrumentation, valving and variable frequency drive controls packages.

Electric Oxidizers
Electric oxidizer achieve destruction temperature using internal heaters to raise the temperature of catalyst blocks.
These units are compact and available with flow rates from 100-600 SCFM and require 208-230/460 V 3 phase power to operate. Standard features include stainless steel construction, process control valve, integrated control panels and exhaust stack extension. Extraction or process blowers can be added onto the skid and integrated to the inlet to provide a turnkey extraction destruction system. MAE2 can provide new, used or rental systems designed to meet your site specific needs.
Gas Fired Thermal and Catalytic Oxidizers
Gas fired oxidizers use propane or natural gas as a supplemental fuel source to achieve destruction temperatures.
These systems are available with flow rates from 100-2500 SCFM. Traditional thermal units destruct vapor via flame incinerations while catalytic units use a heated precious metal block. The systems can be design to be converted from Thermal to Catalytic mode and are easily retrofitted in the field. MAE2 can provide new, used or rental units designed for your specific site needs.
Ozone Injection Systems
Ozone is one of the most powerful oxidants available and is twenty times more soluble in water than oxygen. The byproduct created from the breakdown of hydrocarbons by ozone is oxygen which creates more DO in the groundwater. Much like other injection technologies the key to success is delivery of the proper concentration and contact with the contaminated soils. The Ozone Injection Systems generate ozone on site and allow for easy adjustment of the ozone concentration and total volume. The systems have multiple injection ports to make certain to achieve contact with the contaminated soils. The systems are designed so they can easily be integrated into an existing or new SVE system.
Anaerobic Dechlorination Systems
Anaerobic Dechlorination Systems are designed to deliver substrates and nutrients to create the ideal site conditions for complete dechlorination of TCE, PCE, DCE and VC. The systems provide recirculation of the amended water throughout the site for maximum contact with the contaminated soils. The continuous operation allows for the correct mass delivery, and distribution to prevent biofouling and allow for complete dechlorination without stalling.
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.
