System for Ground Water Remediation at a Power Generation Plant
MAE2 was asked to provide a system based upon detailed written specifications for a Multi Phase Extraction and Groundwater Treatment system. The system is located at a power generation facility.
The detailed specification required that the system be constructed to meet explosion proof NEC Class 1 Division 1 standards. The entire system had to be inspected approved and labeled by MET Labs. The system uses a Busch high vacuum rotary claw pump to extract impacted groundwater and vapors.
The groundwater is collected in a marine grade aluminum vapor liquid separator and a progressive cavity pump moves the liquids to an oil water separator. Any free product is removed and then a centrifugal pump moves the liquid through liquid phase carbon to treat the dissolved phase gasoline. The system is assembled in an 8’ X 20’ once through land sea container that has been customized with framed interior walls, R13 insulation and a 3200W heater.
Finally, the system will provide 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
PLC Control panel
Bag Filter
Carbon Filtration
Oil Water Separator
Vapor Liquid Separator
Centrifugal Transfer Pump
Progressive Cavity Transfer Pump
Biosparge and SVE Systems Combined to Maximize Site Remediation
MAE2 was approached by a consultant to build a system to remediate Chlorinated Solvents in ground water.
Individual Biosparge and SVE Treatment systems were selected to take advantage of the increased efficiency created by combining technologies.
The site is a manufacturing facility that had a release of chlorinated solvents that impacted the soils and groundwater around the facility, including a creek bed. Bio sparging was chosen to provide a steady volume of oxygen into the soils to support the biodegradation of solvents by the indigenous microbe population. Introducing air flow to the subsurface also helps volatilize the contaminants to increase the efficiency of the Soil Vapor Extraction
The SVE Treatment system was designed to extract vapors that were found in the soils near the manufacturing facility. Six wells vacuum wells were installed and screened at different depths in order to influence the entire plume. The Bio sparge injection wells were designed to inject air into 3-4 well zones and an additional aeration well located in the creek bed.
The SVE System included a 10 HP C10 Rotary Claw Vacuum Blower, capable of 255 ACFM @ 15” Hg, an 80G, marine grade aluminum, vapor liquid separator, and a PLC control panel with wireless telemetry. The remote telemetry can be used to monitor the system remotely and send alarm notifications. The system was installed inside a cargo trailer that fit the consultant’s needs and price points.
The Bio Sparge system included a 10 HP Rotary Screw Compressor capable of 35 CFM @ 150 psi. The compressor automatically cycles between different sparge zones via a user programmable PLC controller. The system was enclosed in a 8’ x 10’ steel frame building with custom duct work, 1’’ foam insulation in the walls and ceilings, and temperature monitoring. The controls for the bio sparge system can be remotely accessed via a wireless modem to assess alarms, site performance, or to monitor and adjust the sparge zone timing.
This Air Sparge System uses the following components and subsystems
Relay Based Control panel
Rotary Claw Vacuum Pump
Integrated Air Sparge System at a Space Launch Center
MAE2 was selected as the most responsive bidder in a competitive bid process to build and start up an integrated Air Sparge system for a former maintenance building at a space launch center.
The system was designed to remediate a solvent plume around the former building site. There are 213 wells spread across the site in order to create high air flow and radius of influence across the plume. The system design includes programmable timers that allow the user to rotate air delivery through the different site areas as desired. There are 10 sparge zones on the site, and each can be programmed for specific on off times to optimize remediation.
The project includes remote operation and monitoring so that the performance can be viewed and adjusted as required. The completed system includes a 125 HP variable speed rotary screw compressor capable of providing up to 648 CFM. The compressor automatically adjusts to provide only the air demand needed at any given moment which saves electricity and prolongs the life of the equipment. The system controls display and log temperature, pressure and CFM flow for the compressor and well field areas. The set points and operation timers can be adjusted remotely by phone or computer to maintain optimum efficiency.
The system was installed in a utility trailer custom designed to handle the size and weight of the compressor. Custom duct-work for compressor the intake and exhaust and split unit air conditioners for climate control were designed to keep the interior of the trailer at the low temperature and low humidity that the compressor requires for proper operation.
The system effectiveness was evident as the influence on the water table and in the monitoring wells was immediate.
This Air Sparge System uses the following components and subsystems
Corrective Action Plan for Former Gas Station Site Remediation
MAE2 was approached by a consultant that had performed a Corrective Action Plan and recommended a multi-phase extraction system to perform remediation at a former gas station site.
In order to keep the budget costs low the consultant looked for a high quality, dependable refurbished system. The consultant wanted a reliable system refurbished with attention to detail and consistent long term product support.
MAE2 bought a used system that had successfully completed remediation and site closure from a consultant in GA. MAE2 brought the system back to our facility and completed a custom refurbishment. MAE2 converted the groundwater pumping/SVE system into a multi-phase high vacuum system. We removed the Positive Displacement Vacuum Blower, Reciprocating Compressor and air and water manifold piping. We installed a Rotary Claw Vacuum Pump and Liquid Carbon Vessels. The system components were completely tested and a full O & M and cleaning was conducted to make the system site ready.
The system is a Dual Phase Extraction and Groundwater Treatment system designed for 20 GPM water flow and 325 ACFM vapor flow at 25” HG. There is a 10 point extraction manifold that pulls both water and vapor from the extraction wells using a 15HP rotary claw vacuum pump. The extracted groundwater is collected in the marine grade aluminum 120 G Vapor/Liquid separator and then pumped to an Oil Water Separator (OWS) using a progressive cavity transfer pump.
Any free fuel that is extracted is collected in the OWS and gravity drains into a product holding tank. The water is pumped from the OWS through a bag filter, to remove suspended solids, and then to a Poly Stackable Tray Air Stripper. After the air stripper the water is pumped through two bag filters in series, to remove any remaining suspended solids and two High Pressure Steel Carbon vessels for final treatment before discharge. The OWS pump and Air Stripper pump are centrifugal transfer pumps. The system is controlled by a custom PLC control panel that allows for remote access and control using web based telemetry.
The reuse of an existing system that is custom refurbished provides a proven cost effective solution and reduces capital costs and delivery time.
Components used in this system
Pilot Test and Startup Support.
MAE2 was contacted by a consultant that needed equipment and support for a high vacuum pilot test.
The contractor wanted to run a pilot test to try to get influence in an area of the site the was dominated by above ground storage tanks and railroad tracks. The soils at the site were very tight, requiring a unit that could operate at vacuum levels 15″ HG and higher. They contacted MAE2 for the pilot test unit and additional on-site support and training.
MAE2 provided a Multi-Phase Vacuum System with a Liquid Ring Vacuum Pump. The Liquid Ring Pump is the best option for vacuum applications that require vacuum levels exceeding 24″ HG. Liquids removed during the pilot test collected in the Vapor Liquid Separator and then were pumped to an on site frack tank. The system was connected to a mobile generator to provide electrical power.
MAE2 provided an on-site technician to help with the set up of the system and generator and training on system operation. The system was connected to a horizontal well that was located under the train tracks and tank farm. The pilot test went well and it proved that high vacuum extraction created the desired air flow and influence.
The following system components were used in the pilot system.
Liquid Ring Vacuum Pump
Vapor Liquid Separator
Progressive Cavity Transfer Pump
PLC Control Panel
Refurbished Dual Phase Extraction and Groundwater Treatment System with Thermal Oxidizer
MAE2 was approached by a consultant that had performed a Corrective Action Plan and recommended a multi-phase extraction system to perform remediation at a gas station site.
The consultant also required a thermal oxidizer to treat the vapors removed from the site. In order to keep the budget costs low the consultant looked for a high quality, dependable refurbished system, along with a rental oxidizer.
The consultant knew from experience that they could rely on MAE2 for quality workmanship and long-term product support.
An existing Dual Phase Extraction system refurbished for this project
MAE2 took an existing Dual Phase Extraction system from our fleet and made minor modifications. The control panel was updated with a new touch screen control panel and remote telemetry system. The system components were completely tested, and a full O & M and cleaning was conducted to make the system site ready.
Existing DPE internal view
The system is a Dual Phase Extraction and Groundwater Treatment system designed for 20 GPM water flow and 330 ACFM vapor flow at 25” HG. There is a 12 point extraction manifold that pulls both water and vapor from the extraction wells using two 10 HP rotary claw vacuum pumps mounted in parallel. The extracted groundwater is collected in the 120 G Vapor/Liquid separator and then pumped to an Oil Water Separator (OWS) using a progressive cavity transfer pump.
Any free fuel that is extracted is collected in the OWS and gravity drains into a product holding tank. The water is pumped from the OWS through a bag filter, to remove suspended solids, and then to a Poly Stackable Tray Air Stripper. After the air stripper the water is pumped through two bag filters in series, to remove any remaining suspended solids and two medium pressure steel carbon vessels for final treatment before discharge. The OWS pump and Air Stripper pump are centrifugal transfer pumps. The system is controlled by a custom PLC control panel that allows for remote access and control using web based telemetry.
Dual Phase Extraction system components
The vapors pulled from the ground contain higher concentrations of hydrocarbon than allowed without treatment. MAE2 provided a rental Gas Fired Thermal Oxidizer to destroy 99+% of the hydrocarbons. The oxidizer uses the hydrocarbons pulled from the ground to fuel the thermal oxidizer, efficiently destroying them.
