SRS® Emulsified Vegetable Oil Substrates
SRS® substrates provide a long-lasting carbon source that creates reducing conditions and supports microbial degradation of chlorinated solvents. Designed for flexibility and performance, these emulsified vegetable oil formulations help drive consistent, long-term anaerobic treatment across a wide range of site conditions.
Product Offerings
| Products | Description | Available In | Technical Data Sheet | Safety Data Sheet |
|---|---|---|---|---|
| SRS®–SD | Patented, injection-ready small-droplet emulsified vegetable oil (EVO) substrate containing 60% U.S.-grown soybean oil, 5.5% quick-release substrate, proprietary nutrients, and Vitamin B12 for anaerobic reductive dechlorination. | 264-gal tote 55-gal drum |
