Grey water generated from biofuel conversion processes can pose a burden to downstream processing. Options for grey water treatment and management may affect the operational cost of the plant and environment impacts.

Argonne’s research in this area encompasses:

• Wastewater treatment options for grey water generated from a biorefinery with fast pyrolysis and hydrotreating
• Wastewater treatment options for grey water generated from a biorefinery bio-hydrocarbon via ethanol catalytic process
