In Situ Biological Technology

Specific substrates for specific applications

Make the right calculation : inject the right mass of substrate

• Contamination – nature & concentration
• Background geochemistry - natural matter

Injection phase in the field :

• Very little equipment is required (injection)
• 2 design of injection grid : “cascade” and “barrière”

Monitoring phase : required to achieve the clean-up values

Biodegradable contaminants using aerobic  or anaerobic pathway

• chlorinated solvents,
• hydrocarbons, BTEX
• nitrate, perchlorate...

Scope of application

• Only for plume (dissolved)
• Bio-Barrier design : stop contamination progress
• Polishing phase technology : residual source treatment

Easy to implement in the field

Competitive technology

• Rapid installation phase
• No Operation & Maintenance costs

Long-term remediation process might happen (> 1 year)

INJECTION IMPLEMENTATION is the crucial step requiring a lot of experience.
