Passive Free Phase Remediation Equipment

Passive skimming equipment accumulates free product over time, they do not pump product to the surface. They use floating intake filters that allows only free liquid phase product to enter or absorbent material in cage bailers. The product is removed after the skimmers are brought up to the surface. The goal satisfied by skimming systems is the collection of free product with little or no recovery of water. They also feature low cost and simple operation and maintenance.

Geotech offers two basic forms of passive skimmers:


 

Geotech Passive Recovery Canister (PRC)

2" PRCs4" PRC
2" PRCs with & without protective screen 4" PRC
(cutaway view)

The Geotech PRC (Product Recovery Canister) is a passive skimmer with a floating intake that separates and recovers light hydrocarbons from ground water. The Geotech PRC collects floating product down to a sheen then is emptied through a discharge valve at the bottom of the canister after being raised to the surface.

Viscosity Test Kit

Geotech Hydrocarbon Viscosity Test Kit

The Hydrocarbon Viscosity Test Kit is used to determine hydrocarbon viscosity vs. applicability of the oleophilic/hydrophobic screen technology. It is especially useful when the Geotech Product Recovery System is going to be used to collect varying hydrocarbons.

The test kit comes with a glass container and lid, floatable test screens of 100 and 60 mesh, sample container, and a syringe for injecting the sample. This screen technology is used on Geotech's product line of assorted intake cartridges and Skimmer assemblies.
