A form of WILCLEAR® sodium lactate has been used for years as a food preservative. If you ate pre-prepared meat or mass produced bakery goods for lunch or dinner today, those foods most likely were treated with sodium lactate to give them a longer shelf life.

PROVEN • FAST • EFFECTIVE
RAPIDLY ESTABLISH REDUCING CONDITIONS

BENEFITS

PROVEN

  • Lactate is a proven technology and one of the most efficient electron donors available.

FAST
  • Lactate rapidly establishes anaerobic conditions needed for dechlorination.

EFFECTIVE

  • Lactate provides the perfect concentration of hydrogen needed for rapid dechlorination.
USES

CONTAMINANTS TREATED:

  • Chlorinated solvents
  • Perchlorate
  • RDX
  • Reduction of metals
TREATMENT CONFIGURATIONS:
  • Source area treatment
  • Biobarrier treatment
  • Plume-wide treatment
DELIVERY METHODS:
  • Permanent injection wells
  • Direct push methods

 

   
MICROCOSM STUDY RESULTS  
Microcosm studies comparing WILCLEAR® to other soluble donors show that while all four donors stimulate complete dechlorination of PCE to ethene, WILCLEAR® and ethanol have the fastest dechlorination kinetics.

  • Water (wt/wt): 40 ± 1.2%
  • pH: 7.5 ± 1.0
  • Specific gravity: 1.2 - 1.3
  • Soluble in water
  • Color: Clear to light straw
  • Viscosity: 100 cP at 68°F

 

HANDLING
  • Store unopened under dry conditions at temperatures between 35°F and 85°F.
  • Shelf life of unopened product is 2 years
  • Opened product should be used within 30 days
  • Diluted product should be used within 5 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.
