Floating inlet automatically adjusts to water table changes.

Application:

• Passive LNAPL recovery
• Use when minimal product is present or slow recovery rates are expected
• 2" and larger wells
• May be upgraded to an active system by adding the F.A.P. Plus™ Pump

Description

• Skimmer
• Canister Well Clincher with 30 ft cord

Skimmer
The Passive Skimmer utilizes the F.A.P. Plus™ skimmer to provide a 36 in floating intake for the recovery of free phase products such as gasoline, diesel and jet fuel. It is used when minimal product is present or slow recovery rates are expected. For passive recovery of products with higher than 80 SSU, the 4 in high viscosity skimmer (TR-25410) is used. This system provides a floating intake of 30 inches.

Product Recovery Canister
The clear PVC collection canister uses a quick connect fitting to attach it to the skimmer and provides venting through the skimmer support hollow rod. The bottom of the canister incorporates a petcock for easy draining. The petcock assembly can be removed allowing an extension canister to be threaded into the existing canister to increase the volume of free product that can be recovered. Additional weights are included with each canister and must be used for proper installation.

Well Clincher and Cord
The Well Clincher and 30 ft Nylon® suspension cord are used to support the passive skimmer in the recovery well. The clincher incorporates an eye hook to attach the suspension cord. Correct measurement of the product water interface is necessary to properly position the passive skimmer.

Tech Tip. The critical measurement for proper recovery is from the bottom of the well to the product water interface. Custom canisters are available for shallow well applications.

Absorbent material for immediate response or minimal product.

Application:

Passive LNAPL recovery

SoakEase™ is a product-selective absorbent sock inside a stainless steel canister. It is used as a passive collection system for free phase product such as jet fuel, gasoline or diesel fuel from 1 in (2.4cm) and larger recovery wells, monitoring wells and recovery trenches.

Description

SoakEase™ is 36 in (0.9 m) long and is available in three sizes to accommodate specific site requirements

1 in. absorbs 0.18 quart (0.47 L) of product per sock
2 in. absorbs 1 quart (0.95 L) of product per sock
4 in. absorbs 3 quarts (2.8 L) of product per sock

The SoakEase™ can be used as a bailer for periodic product removal or as a dedicated system for a more continuous method of recovery. Prior to dedicating the SoakEase,™ it is recommended that excess free product be removed by bailing with the SoakEase™.

To use SoakEase™ as a bailer, an absorbent sock is placed in the stainless steel canister, a cord is attached to the support loop and then lowered through the product layer. The full length of the sock should come into contact with the product for greater recovery. Immediately the SoakEase™ will begin absorbing product at a rate of approximately 0.1 gallon (0.38 L) per second, depending on the product viscosity. After some time, the SoakEase™ should be raised from the well, the sock removed from the canister and disposed of in accordance with regulations.

To use the SoakEase™ as a dedicated system, it is necessary to determine the amount of product present using an oil/water interface indicator as well as the water table fluctuation. When these have been determined, the SoakEase™ may be installed to accommodate level changes of up to 36 in (0.9 m).

Tech Tip: The product absorption rate is determined by the viscosity of the product and can vary depending on site conditions. The SoakEase™ is designed to be used with hydrocarbon-based products. The user must determine the necessary replacement schedule by gauging site conditions. The socks can be squeezed out and reused. Approximately 80% of the original absorption can be recovered.
