iSOC™

iSOC™, or in situ Submerged Oxygen Curtain, is based on iTi’s proprietary Gas inFusion™ technology. Its inherently large surface area allows for intimate contact between oxygen and groundwater, resulting in ultra efficient mass transfer.

Although used to enhance natural bioremediation of hydrocarbons in groundwater with oxygen, iSOC™ can also be used to infuse any gas into groundwater, including gases used to enhance natural degradation of chlorinated solvents.

The iSOC™ unit is made of stainless steel and is 1.62 inches in diameter and about 15 inches in length. The sizing is to allow the iSOC™ to be placed inside 2 inch diameter groundwater monitoring wells.

The top of the unit is equipped with a ‘push-loc’ fitting to accommodate the ¼ inch diameter Polyflow tubing used to connect the unit to a source of pressurized oxygen, usually a liquid oxygen cylinder. Although the tubing and fitting will support a considerable tensile strength, a ‘lifting eye’ is also installed on the top of the unit for attaching a lifting/security wire.

The bottom section of the iSOC™ unit drains and collects any water which may occur in the infusion section due to improper operating conditions. The drain fitting on the bottom allows this water to be drained and the unit to be ‘blown’ clear.
