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

Recurring questions we get

F.A.Q

Enhanced reductive dechlorination is based on attaining and maintaining control of an aquifer for a period of time sufficient to degrade all constituents of concern and their daughter products. Attaining and maintaining control of an aquifer is highly dependent on the hydrogeology and geochemistry of the site along with the microbial populations present. Since the hydrogeology and geochemistry is different for every site, a blanket cost can not be given for any specific site. In general, enhanced reductive dechlorination will cost less than $10 per cubic yard of media treated on most non-DNAPL sites. This compares with about $60 per cubic yard for excavation (without disposal) and about $90 per cubic yard for chemical oxidation.

In some cases, MCLs can be attained with enhanced reductive dechlorination. Much more frequently, reductions in contaminant mass of one to two orders of magnitude are common.

Because freight is costed from a warehouse to a delivery point, freight costs are quoted separately. Unless otherwise stated, due to the volatility of the fuels market, freight costs are generally valid for 30 days. Consideration should be given to the receiving facility’s capacity to off load a truck. In situations where the product is delivered to a facility without the capacity to off-load a delivery vehicle, arrangements can be made (for an additional charge) for delivery on a vehicle with a lift gate and pallet jack.

Reinjection schedules should be based on the geochemistry of an aquifer and not on a calendar schedule. In many cases, multiple injections can be spaced further apart over time.

Since the main goal of adding a substrate to an aquifer is to attain and maintain anaerobic conditions for an extended period of time, because of the limited flows clay sites should be ideal for enhanced reductive dechlorination. In practice, clay sites with adequately spaced injection points usually show very rapid response to substrate addition.

Injection spacing should be sufficient to promote robust reductive dechlorination throughout the treatment zone for a time sufficient to attain complete reductive dechlorination. Injection spacing is dependent upon the dissolution rate of the substrate, the dosage, aquifer velocity, and competing electron acceptor and contaminant flux.
