Terra Systems QRS - Sodium and Potassium Lactate Quick Release Substrates

Proprietary nutrients and Vitamin B12 can be added to sodium or potassium during the manufacturing process and has been statistically demonstrated to support biodegradation of chlorinated solvents with soluble substrates like lactate and emulsified vegetable oil. (He et al 2007 and Harkness et al 2012).

• 60% QRS^™-SL sodium lactate is an inexpensive, soluble, food grade substrate for the biodegradation of chlorinated solvents such as tetrachloroethene (PCE) and trichloroethene (TCE)
• 60% QRS^™-SL Plus sodium lactate contains our Proprietary NutriPlus™ nutrient (Harkness et al 2012) and Vitamin B₁₂ package (He et al 2007), which supports enhanced in-situ bioremediation and increases dechlorination kinetics and donor efficiency.
• 60% QRS^™-PL potassium lactate is an inexpensive, soluble, food grade substrate for the biodegradation of chlorinated solvents such as tetrachloroethene (PCE) and trichloroethene (TCE). It is often used in areas of Florida and California, which have restrictions on the amount of sodium (such as sodium lactate) that can be injected.
