- •
Anaerobic systems provide for higher Cr(VI) removal rates compared to aerobic systems.
- •
Complete microbial Cr(VI) reduction is achieved under anaerobic conditions.
- •
Easily degradable substrates support higher Cr(VI) removal rates than complex ones.
- •
Cr(VI) removal rates follow the Arrhenius equation for temperatures between 12 °C–33 °C.
- •
Sand filtration as a polishing step provides for complete Cr removal from groundwater.
