Coagulation, oxidation and disinfection are common treatments in drinking water
production. The ferrate ion (FeO42-) combines oxidation and coagulation. In this paper
the removal of turbidity, total organic carbon (TOC), E. coli and color by ferrate dosing to six Dutch water
types is described. Also the improvement of UV-transmission was investigated. Jar
tests showed poor coagulation under the chosen conditions, but a reasonable amount
of UV absorbing and color components could be removed. Furthermore a 3-log
inactivation of E. Coli could be achieved. Due to its oxidizing properties, application
of ferrate results in AOC formation. Includes 8 references, tables, figures.
