LactOil®

• 98% fermentable blend containing both quick release ethyl lactate and slow-release long-chain oleaginous materials.

• Designed for sites where a slow-release substrate is needed (i.e. sites with high mobilization/injection costs), DNAPL source treatment, PRBs, cutoff walls.

NOT JUST ANOTHER EMULSIFIED VEGETABLE OIL

Usage Estimation

Application Corner

Our approach to substrate dosing is based on site conditions. JRW Bioremediation L.L.C. provides substrates and nutrients for anaerobic bioremediation. The substrates provided include highly soluble materials such as WILCLEAR® sodium and potassium lactate, SoluLac® ethyl lactate, and Wilke Whey® whey powder and slowly soluble substrates including LactOil® soy microemulsion, and ChitoRem® chitin complex.

Fun Facts
Fun Facts - JRW Bioremediation, LLC

In the saturated zone, microemulsion particles will act as colloids. A variety of natural colloids exists, including clays, oxides, minerals, bacteria, and organics, with the concentration ranging from 108 to 1017 particles/L. Factors that affect the distribution of colloids include advection, diffusion, dispersion, and sorption. Straining of particles occurs when the pore throats are too small to allow the particle passage, which can reduce permeability (Bradford, S. et al. 2002. Physical factors affecting the transport and fate of colloids in saturated porous media. Water Resources Research, Vol. 38, no.12, 1327.)

High Fermentable Content

  • High organic content (over 95%) provides up to 30% more fermentables than standard emulsified vegetable oils.

Easy Material Handling

  • Low viscosity; readily mixes with water; no high shear mixing needed
  • Low injection pressure.
  • Longer shelf life

Increased Subsurface Distribution

  • Thermodynamically stable
  • Small particle size

Handling

  • Store unopened under dry conditions at temperatures between 50°F and 85°F.
  • Diluted product should be used within 3 days to avoid microbial growth and activity which may cause gas buildups in containers and visible growth which may foul equipment.
  • Following injection of material, wells should be flushed with clean water to prevent microbial growth.
