Short Term Rental System for a Groundwater Re-circulation Event at a City Gas Station

MAE2 installed a flexible pump and treat system for groundwater remediation, from our fleet of available rental systems.

MAE2 worked with a consultant who needed a pump and treat system to extract groundwater from two wells and then re-inject the treated water. The project scope called for a 1-week site event and a flexible, and readily available system was required.

MAE2 provided an existing trailer mounted system from our fleet and modified it to meet the site specific needs of the short term event. MAE2 fabricated a custom reinjection manifold to make it easy to control the flow into the injection wells. The system components were completely tested before shipping to make certain the system was ready to run on site with no downtime.custom reinjection manifold

The system is a Pump and Treat and Groundwater Treatment system designed for up to 30 GPM water flow. MAE2 provided 2 QED AP4+ Pneumatic Groundwater Pumps complete with downwell air, water discharge and exhaust hoses and well caps.

The system had a Reciprocating Air Compressor connected to an air supply manifold that included pressure and flow controls. Air hose was used to connect the trailer air supply manifold with the downwell pneumatic pumps. The water discharge from the pumps connected to the multi point extraction manifold. The manifold piped the extracted groundwater to an Oil Water Separator to remove any free product gasoline. Any free fuel that is collected gravity drains into a product holding tank. A centrifugal transfer pump sends the water to a Poly Stackable Tray Air Stripper. The Air Stripper removes any dissolved phase gasoline from the water. The water is then pumped through a bag filters in parallel and two high pressure steel carbon vessels for final treatment before discharge.

The pump control allows control of the pressure and flow and the custom fabricated injection manifold allows the user to fine tune the injection volume for each well. The system is controlled by a custom PLC control panel that allows for remote access and control using web-based telemetry.

This Environmental Remediation System uses the following components and subsystems

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.
