Dehalococcoides ethenogenes strain 195 uses only H2 as an electron donor and chlorinated compounds as electron acceptors to support growth. In culture, it also requires acetate, vitamin B12, and extracts of mixed microbial cultures as nutrients (Seshadri et al. 2005 Genome Sequence of the PCE-Dechlorinating Bacterium Dehalococcoides ethenogenes, Science, vol 307, pg. 105-108).

FAST • EFFECTIVE • ECONOMICAL
SAY GOODBYE TO YOUR CHLORINATED CONTAMINANTS

BENEFITS FAST Lactate provides carbon for rapid establishment of anaerobic conditions EFFECTIVE Volatile fatty acids provide a range of material to promote growth of an assortment of dechlorinating microbial populations. Accelerite nutrient blend provides growth factors to increase dechlorination kinetics and donor efficiency. ECONOMICAL	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
Wilclear Plus® demonstrated faster dechlorination kinetics than other substrates. At 25 days, the Wilclear Plus® microcosm converted more than 99% of PCE to ethene.
TYPICAL PROPERTIES Sodium lactate (wt/wt): 29-35% Sodium propionate (wt/wt): 0-8% Sodium acetate (wt/wt): 0-8% Sodium butyrate (wt/wt): 0-8% Carbohydrates/metabolites (wt/wt): 21-25% pH: 7 ± 1.0 Specific gravity: 1.2 - 1.3 Soluble in water Color: light to dark brown Viscosity: 500-1000 cP at 68°F (may become more viscose in cold temperatures). The design of pumping and metering systems will need to take this viscosity into account If equipment restraints require a less viscose material, Wilclear® 60% sodium lactate and Accelerite® nutrient blend can be provided separately and mixed onsite.   HANDLING Store unopened under dry conditions at temperatures between 35°F and 85°F. Shelf life of unopened product is 1 year Opened product should be used within 7 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.   PACKAGING 5-gallon pails 55lbs 2-3 weeks lead time required past receipt of a PO 55-gallon polyethylene drums 600lbs 2-3 weeks lead time required past receipt of PO 265-gallon IBC totes 2750 lbs Special order - 4 weeks lead time required past receipt of PO Tankers Special order - please contact us for specifics
