Passive Skimmer

Recover the free-phase hydrocarbon (LNAPL) without pumps.

Passive Skimmer Specifications

Choosing the Right Passive Skimmer
Specific Gravity and Viscosity are two of the most important properties of the hydrocarbons (LNAPL) as far as their mobility in the subsurface. At the same time that these parameters affect the migration of the plume, they also play a very important role in the selection of the right skimmer for the cleanup application.
