Zusammenfassung:PCT No. PCT/AT93/00110 Sec. 371 Date Feb. 25, 1994 Sec. 102(e) Date Feb. 25, 1994 PCT Filed Jun. 30, 1993 PCT Pub. No. WO94/00388 PCT Pub. Date Jan. 6, 1994.According to a process for lowering the phosphorus content of waste water, the waste water flows in a purification circuit through individual conditioning basins, such as a preliminary sedimentation basin, an activation basin, final sedimentation basin or the like. In order to reduce the phosphorus content in a rational, ecological and efficient manner, the waste water is subjected to an electrolysis in one of the conditioning basins, preferably in the activation basin, by means of metal electrodes and of an electric direct voltage.
