EOS - Model QR - Quick Release Soluble Substrate
From Emulsified and Water-Mixable Oils
EOSQR is a quick release soluble substrate for rapid fermentation and short-lived electron donor addition. EOSQR is designed to pre-condition the aquifer creating a highly reducing redox state and initiate enhanced anaerobic dechlorination of contaminated groundwater. EOSQR serves as an excellent pre-treatment prior to an emulsified oil substrate (EOS) injection.
Details:
Water soluble organic substrate to pre-condition the groundwater before emulsified oil injection or as a short-term stand alone treatment of chlorinated solvents
Product Advantages
- Compatible with EOS oils, CoBupHMg, and BAC-9
- Sodium free
- “Jump starts” bacterial growth
- Soluble in water
- 99% food-grade fermentable carbon
- 2x hydrogen release compared to sodium lactate
EOSQR Benefits:
- A food grade substrate without sodium; ideal for salt-sensitive aquifers
- Rapidly-biodegradable substrate to “jump start” bacterial growth
- Soluble in water for excellent transport in the subsurface
- Provides more electron equivalence per pound than sodium lactate
