Active High Rate Dissolved Gas Substrate Delivery
•gPRO^® High Pressure (HP) and gPRO^® Low Pressure (LP) systems rapidly infuse gases up to saturation in high flow water systems
•gPRO^® HP for ex situ infusion at or above
ambient pressure
•gPRO^® LP for ex situ or in situ applications at ambient pressure

How does gPRO^® LP Work?
•Thousands of microporous hollow fibers filled with holes
•Provides enormous surface area for mass transfer (7000 sq ft per cu ft)
•Water is saturated with dissolved Hydrogen (H2)
•High levels of dissolved H2migrate to surrounding biomass
•Microbial population increases and degrade targeted compounds

What is gPRO^® LP
•A superior gas delivery system based on inVentures’Gas inFusion Technology
•Mass transfer device delivers high amounts of dissolved hydrogen to treatment zone
•gPRO^® LP system is submerged directly into the body of water
•System powered by compressed gas in cylinder

SupersaturatedWater Injection (SWI)
•LNAPL and DNAPL recovery enhancement system for trapped and immobile NAPL mass
•Uses carbon dioxide to strip volatile NAPL component for capture in the unsaturated zone
•Mobilizes liquid NAPL trapped in aquifer matrix for recovery
