Heating Oil Removal System for an Apartment Building

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 goal is to remove heating oil from the groundwater, removing any long-term liability concerns for the apartment complex owners

MAE2 built the system using a custom modified cargo container. The enclosure consisted of two rooms. The first room contained the control panel and the air supply compressor. The second room included the water treatment system and was built to meet the requirements for Class 1 Div 2 hazardous environments. Both rooms included lights, ventilation fans and heat. The system components were completely tested before shipping to make certain the system was ready to run on site with no downtime.

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.

Pump and Treat and Groundwater Treatment system

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 heating oil. Any free fuel that is collected gravity drains into a 250 gallon product holding tank. A centrifugal transfer pump sends the water to two parallel high pressure fiberglass carbon vessels for treatment before discharge. The water passes through a flow totalizer to record total gallons treated prior to discharge to sanitary sewer. The system is controlled by a custom relay control panel that includes an externally mounted flashing alarm light.
