history

The reasons for the establishment of the plant were the connection to the Rheinisch-Westfälisches Elektrizitätswerk AG in Knapsack (Hürth) and the flood-free access to the Rhine . Construction of the plant began in 1913 and was completed in 1914. This included the Kleinbahn Siegburg – Zündorf , which was built to connect the plant to the transport system. The first forty-cell electrolysis was carried out on April 7, 1914 .

Initially, using the Wildermann method, potassium chloride and sodium chloride were electrolytically decomposed. The procedure was replaced by the Siemens Billiter procedure . In 1923, 56 Siemens Billiter cells were used for production.

In 1925 this was used to produce aluminum oxide . By melting bauxite in an electric arc furnace, it was obtained as an artificial abrasive. Seven electric arc furnaces were built by 1943.

Both the First and the Second World War and the currency reforms brought severe setbacks for the plant, but in 1960 around 1200 workers were employed at the Feldmühle plant.
