System Components
Mobile Injection Trailer
Mobile Injection Trailers are ideal for sites with low concentrations, residual “hot spots”, or site specific goals like product removal. The injection trailers can be custom built to meet your needs. A typical mobile trailer will include a generator for power supply, electric extraction pumps, water tank, mixing tank, discharge tank, discharge pump, bag filtration, carbon treatment, and extraction and injection manifolds. This design is great for the application of chemical oxidants (hydrogen peroxide, permanganate, etc.), surfactant recirculation, and biological amendments.
Injection Platforms
The introduction of biological amendments, oxygen, chemical oxidants, nutrients, and surfactants can be very effective in reducing or degrading contaminants in soil and groundwater. The key to success for any of these approaches is contact with the contaminated soils. Continuous Injection and Recirculation can overcome the inefficiency associated with typical “slug” injection approaches. MAE2 has several injection platforms designed to achieve the contact and treatment your site requires.

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.

Liquid Ring Pump Systems
LRPs should be coupled with an inlet particulate filter-Integral seal oil reservoir with low oil level switch, coalescing air-oil separator element, pressure gauge, and sight glass air cooled seal oil heat exchanger with temperature control valve, high temperature switch and vacuum relief valve.
Rotary Claw Blowers
Rotary Claw Blower systems can operate in full range of vacuum with minimal maintenance issues. Rotary claws come in a wide range of horse power and can be plumbed in parallel to achieve higher airflow rates. The claw blowers should be coupled with an auto oiler to prevent lobes from seizing during long term shut down.
Vapor liquid separators should be installed prior to the rotary claw pump to prevent moisture carry over and transfer collected liquids to discharge point.

Soil Vapor Extraction Systems
Soil Vapor Extraction (SVE) Systems are designed to induce vacuum and air flow to the subsurface to enhance removal of contaminants in the soil.
SVE Systems typically operate in ranged of 50” water column vacuum up to 15” Hg vacuum. A wide variety of blowers can be used based on the required vacuum and flow. Typical industry standards include regenerative blowers for low vacuum and low to moderate flow rates and positive displacement blowers for higher vacuums and higher flow rates. These types of blowers can be coupled with a variable frequency drive that allows the operator to adjust the rotational speed to match the site specific requirements.
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.
Options
- Skid mounted, open trailer, enclosed trailer, custom enclosure or custom building
- Centrifugal / progressive cavity automatic pump out with level controls in clear sight tube
- SVE Blower lobe auto oiler
- Filter Vessels
- Liquid Phase and Vapor Phase Carbon Vessels

Oxidizers
MAE2 offers Thermal and Catalytic Oxidizers to treat off gas of groundwater and vapor extraction systems along with plant process air.
These modular units are fully skid mounted with gas train, safety valves, process and dilution blowers and Nema 3R UL listed controls. Each system can be purchased as standalone units or integrated with extraction blowers and quench scrubbers.
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.
