QED Passive Skimmers
Passive Skimmers have been designed for product-only (LNAPL) recovery applications in sites where active pumping systems are not applicable due to existing conditions or extreme low permeable formations. The floating intake head follows the groundwater fluctuations in the recovery well, allowing only the free-floating phase (LNAPL) to be captured without taking water and stored in the built-in reservoir for further manual transfer to a tank.
