Abstract :
The sludge dissolution kinetics and corrosion of materials were quantitatively evaluated when iron oxide removal solvents containing EDTA were applied at temperatures ranging from 93 to 150 °C. Periodic ventilation and excessive EDTA concentration were evaluated as alternatives to enhance the sludge dissolution kinetics. Magnetite dissolution was drastically accelerated as the temperature was raised up to 150 °C, while the amount of corrosion was well controlled within an allowable limit.
