Field study III: evidence gained from site studies for the performance of ferrate(VI) in water and wastewater treatment

Research output: Chapter in Book/Report/Conference proceedingChapter (peer-reviewed)

Abstract

The work presented in this chapter was to validate whether ferrate(VI) can be used as an alternative to the existing coagulant (e.g., ferric chloride) for both drinking water and domestic sewage treatment via a series of pilot-plant trials. For drinking water treatment, a ferrate(VI) dose of 0.1 mg/L can achieve 93% and 97% particle removal (in terms of particle counting) after the filtration for the raw water and for the ozonized water, respectively, which is satisfactory to the treated water quality demand for the particle removal. Moreover, ferrate(VI) can remove 10% metformin, benzotriazole and acesulfame from raw water, but FeCl3 with ozonation cannot. When treating domestic sewage at pilot-scale trials, ferrate(VI) demonstrated encouraging performance as well; at a very low dose range, 0.1–0.2 mg Fe(VI)/L, ferrate(VI) achieved better performance in comparison with high-dosed ferric sulfate. This will reduce chemical demand and sludge production, and, therefore, it results in a low operating cost and substantial cost saving in treating sewage.
