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.

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.
