“…Moreover, the disinfection towards E. coli was also comparatively better than hypochlorite. In a line the comparative performance of ferrate(VI) with ferric sulfate and aluminum sulfate are carried and reported that ferrate possessed better treatment chemical (cf Table 8) [91]. Fig.…”

“…A previous study had demonstrated that even for the similar dose of ferrate(VI) and ferric(III), the sludge production from ferrate(VI) was less than that from ferric(III) (Jiang et al, 2006b). This is an extra benefit for the use of ferrate(VI) in full scale wastewater treatment in terms of reducing the cost for sludge handling.…”

This paper aims to study a relative new technology, the online generation and application of ferrate(VI), for sewage treatment, from pilot to full scale trials at Hailsham North Wastewater Treatment Plant of Southern Water Ltd of UK. The work presented in this paper has significant impact on the use of ferrate(VI) in water and waste water treatment practice; the online production and application of ferrate(VI) resolves problems of the instability and needs no transportation. The current efficiency of ferrate(VI) generation was up to 70% through the developed system, which is relatively high. For achieving the same phosphorus removal target from the crude sewage, the ferrate dose required was in a very lower range, 0.01 -0.2 mg Fe 6+ /L in comparison with high doses of ferric sulphate; these will reduce the chemical demand and sludge production and therefore result in a low operating cost and generate substantial cost saving in treating sewage.

“…Ferrate salts are very strong chemical oxidants. As they are being reduced, they produce ferric hydroxide which additionally serves as a coagulant agent [17], [18]. Two main compounds usually used are sodium ferrate (Na 2 FeO 4 ) and potassium ferrate (K 2 FeO 4 ).…”

Abstract-The goal of this experiment is to evaluate the effectiveness of different leachate pre-treatment options in terms of COD and ammonia removal. This research focused on the evaluation of physical-chemical methods for pre-treatment of leachate that would be effective and rapid in order to satisfy the requirements of the sewer discharge by-laws. The four pre-treatment options evaluated were: air stripping, chemical coagulation, electro-coagulation and advanced oxidation with sodium ferrate. Chemical coagulation reported the best COD removal rate at 43%, compared to 18% for both air stripping and electro-coagulation, and 20% for oxidation with sodium ferrate. On the other hand, air stripping was far superior to the other treatment options in terms of ammonia removal with 86%. Oxidation with sodium ferrate reached only 16%, while chemical coagulation and electro-coagulation removed less than 10%. When combined, air stripping and chemical coagulation removed up to 50% COD and 85% ammonia.
