Wilclear® Lactate Concentrate

1 of 1 products in this brand
Wilclear® Sodium Lactate 60% Solution is a food grade 60% sodium or potassium lactate solution that has been deployed at U.S. Department of Energy sites and military installations, Superfund sites, mining sites, Brownfields, industrial sites, private chemical plants, and dry cleaners across North America and Europe. To date, WILCLEAR® has been used on over 250 projects in nearly every state in the US, including Hawaii and Alaska. Wilclear® is a readily soluble food grade 60% sodium or potassium lactate solution. It is great for sites where rapidly established anaerobic conditions are needed, nitrate reduction, and perchlorate degradation.

    Benefits of Wilclear®
    • Provides carbon for rapid establishment of anaerobic conditions needed for reduction of nitrate, hexavalent chromium, perchlorate, and RDX.
    • Miscibility in water and low viscosity allow for advective transport with groundwater; enhancing subsurface distribution and minimizing the number of injection points.
    • Effective for both dissolved phase and DNAPL source area treatment.
    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.

    Technical Details & Test Data

    Rapid Dechlorination Kinetics

    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.

    Greater Donor Efficiency

    Efficiency (amount of contaminant remediated per unit donor added) should be considered when determining donor cost performance. Of the three donors that show both complete dechlorination and reasonable remediation rates, lactate has the best efficiency.

    Storage & Handling

    Shelf Life
    2 Years (Unopened)
    Storage and Shelf Life
    • Store unopened under dry conditions at temperatures between 35°F and 85°F.
    • The shelf life of the unopened products is 2 years
    • The opened product should be used within 30 days
    • Diluted products 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.
