It is well known that a consortium of microbes is needed for complete degradation of PCE or TCE to ethene. Because each of these microbes may have its own nutrient requirements, a single limiting nutrient may not be applicable to heterogeneous groundwater populations. A blend of nutrients is therefore preferred

Effective Economical
Increase your donor efficiency and kinetics

BENEFITS

EFFECTIVE

  • Increases the efficiency of electron donors.
  • Increases the rate of dechlorination to ethene.
  • Stimulates microbial growth and promotes the production of propionate over acetate.

ECONOMICAL

  • At a usage rate of 3% the fermentable fraction of your electron donor, adding Accelerite® costs pennies on the pound per total electron donor utilized.

USES

DONOR ENHANCED:

  • Lactates
  • Emulsified Vegetable Oils
  • Volatile fatty acid blends
  • Solids such as chitin and whey powders

 

CONTAMINANTS TREATED:

  • Chlorinated solvents
  • Perchlorate
  • RDX
  • Reduction of metals

 

 

   
MICROCOSM STUDY RESULTS  
Typical biomass response to substrate input without Accelerite® - one magnitude of increase seen after 90 days. Biomass response with Accelerite®, 2 orders of magnitude increase is seen after only 12 days.
Estimated efficiency increased over 5 times with addition of Accelerite® (estimated efficiency calculated as umoles electron donor used for dechlorination divided by the as umoles of electron donor added).  
   
TYPICAL PROPERTIES
  • Contains growth factors, vitamin B12, and other micronutrients.
  • moisture (wt/wt): < 75%
  • Protein (wt/wt): > 7%
  • Fat (wt/wt): > 0.5%
  • Ash (wt/wt): > 0.5%
  • Dispersible in water
  • Color: dark brown

 

HANDLING
  • Store unopened under dry conditions at temperatures between 35°F and 85°F.
  • Shelf life of unopened product is 1 year
  • 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.
  • Equipment decontamination should follow site specific requirements. In most situations, any product residual should be flushed into the aquifer and then chased with clean water.
