- •
Speciation and bioavailability of Fe during organic shock loads was studied.
- •
Effects of Fe2+ on the degradation of VFAs during organic shock loads was examined.
- •
The implications of Fe accumulation in the seed sludge was demonstrated.
- •
Fe existing as sulphide salts appeared to be bioavailable to the methanogens.
- •
Fe addition during organic shock loads enabled rapid removal of acetate in SAMBR.
