An European project has been completed by a consortium of eight university and industrial partners with the following objectives: 1. Produce large lots of potassium ferrate to supply applications research; the pilot plant used a mixing technology of powders described earlier. 2. Develop a new fluid bed technology easier and safer to scale–up to large capacity. 3. Develop a process using cheaper raw materials like caustic soda and chlorine or hypochlorite. 4. Carry a large range investigation of applications in drinking water, in municipal wastewater treatment, in industrial wastewater and in other fields where a strong oxidant can be used. 5. Collect also all relevant information on the competition of chemicals or systems actually used in water treatment. This paper describes the significant progress made in the synthesis of solid sodium and potassium ferrate(VI).
