Animation illustrates enhanced plume contamination recovery through the injection, and recovery, of Ivey-Sol® into, and from, the subsurface. Ivey-Sol® injections interact with subsurface contaminants, decreasing absorption and adsorption factors thereby increasing contaminant mobilization and dissolution, leading to enhanced plume mass recovery. Enhanced recovery reduces remediation time for site closure over typical pump-and-treat systems.

Time 0:00-0:18 highlights the placement of a primary recovery well (bright green) at the plume center (green) and injection wells (red) at the periphery. The recovery well initiates pumping, drawing down the groundwater table and recovering partial contaminate mass dissolution.

Time 0:18-0:37 highlights the Ivey-Sol® injection diffusion (red) into the contaminant mass (green) forming a heterogeneous mixture (orange) as mobilization leads to enhanced mass recovery.

Time 0:37-0:45 highlights the reduced contaminant mass, enhanced plume dissolution & desorption (orange), as pumping at the recovery well ceases and the groundwater table returns to static levels.

Enhanced recovery reduces remediation time for site closure over typical pump-and-treat systems.

Time 0:00-0:10 highlights the location of an injection well field, a recovery well field, a capture zone and plume limits.

Time 0:10-0:25 highlights the upgradient Ivey-Sol® injection (red-orange) into the downgradient contaminant mass (green) forming a heterogeneous contaminant mixture (orange). The capture zone outlines the extent of the groundwater drawdown and inflow of the heterogeneous contaminant mixture into the recovery wells.

Time 0:25-0:45 highlights the reduction of Total Petroleum Hydrocabons (TPH) in the contaminant mass (orange). Concentration contours (green, yellow, red) illustrate TPH reduction from high to low, during contaminant mass recovery from the periphery to the center of the plume mass.

Time 0:00-0:16 highlights placement of dual injection and recovery wells based on the injection and diffusion radius of Ivey-sol® within the plume limits. Well placement is further determined by site soil types (clay, silt or sand) and overlap of diffusion haloes.

Time 0:16-0:36 highlights the Ivey-Sol® injection (red), subsequent groundwater mounding, and radial diffusion halo within the vertical contaminant plume mass (green).

Time 0:36-0:45 highlights recovery of heterogeneous Ivey-Sol® and contaminant mixture (orange) in the subsurface through pumping of recovery wells (dually used as injection wells).

Animation illustrates injection of Ivey-sol® particles through an injection gallery into the subsurface. Ivey-sol interacts with contaminants, increasing mobility through dissolution and desorption from the soil matrix. The mixture of contaminant and Ivey-sol product enters a controlled water table gradient, passed a monitoring well used to observe water quality, and into a recovery well.

At 0:25 we zoom into the soil matrix to observe how Ivey-sol particles attach to contaminant mass, desorbing from the soil matrix, allowing enhanced dissolution and mobility into the water table aquifer, to be captured through groundwater pumping of the recovery well.

Animated flow diagram illustrating the use of Ivey-sol surfactant in ex-situ soil washing system.

Hydrocyclones are used to separate sand particles from sludges, and are integral to soil washing processes.

This Test render depicts the use of a hydrocyclone to separate denser large particles to lighter smaller particles.

The smaller particles escape through the over pressure area in the vortex of the centrifugal forces; the underpressure drops the larger particles through the bottom.

A simulation of a buried contamination source consisting of barrels  containing Dense Non-Aqueous Phase Liquids (DNAPL) and Light Non-Aqueous  Phase Liquids (LNAPL).    The simulation is a pseudo-physical simulation.  Contaminant particles  follow either gradients provided by the groundwater surface (LNAPL) or  gravity and groundwater gradients (DNAPL).  DNAPL particles on contact  with an Aquitard tend to follow the slope of the aquitard and may move  contrary to the groundwater flow direction.  The simulation does not  fully conceptualize dispersion or other limiting forces to contaminant  transfer.  The simulation was prepared by Eric Xanderson (Eric@lorefolk.com) and  constructed primarily in Blender (http://Blender.org).
