Air Strippers
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.
This Remediation System uses the following components and subsystems
Rotary Claw Vacuum Pump
Poly Stackable Tray Air Stripper
PLC Control panel
Oil Water Separator
Vapor Liquid Separator
Centrifugal Transfer Pump
Progressive Cavity Transfer Pump
Reciprocating Air Compressor
Down well Pneumatic Pumps
Diffused Aerator Air Strippers
Diffused Aerators can achieve 99% removal efficiency and use a serpentine pattern designed aerated chamber. A blower provides the required air through proprietary fine or coarse bubble diffusers. The water then cascades into the last quiescent chamber and out of the system. Air stripping of the contaminant is achieved in the aerated chambers without media or moving parts. It is a compact, low maintenance, and low cost alternative to filters, packed towers, and mechanical aerators for the fast and efficient removal of dissolved gases and volatile organic.

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.
Removable Tray Air Strippers
Removable tray air strippers are the only high-performance strippers with lightweight stainless steel body and front-slide out trays. They provide many advantages such as one-person cleaning, front serviceability and forced-draft air bubble technology. With flow rates range from 25-1000 GPM the removable tray low profile design allows them to be installed in mobile trailer, buildings and steel base skids.
Air Strippers
Air Strippers are used to remove volatile organic compounds (VOC) from groundwater and process water with removal efficiencies up to 99%. These air strippers are engineered to serve in small water treatment projects or larger, process-type projects involving multiple treatment stages. They can act as a pre-treatment stage for other process elements, such as large aerobic bio-treatment units, removing VOCs at much lower airflow rates to reduce the costs of off-gas treatment.
