Hydro Ingenieure - Vision to clear solutions

Interplant wastewater treatment Laufen Austria AG

Tasks definition

Due to capacity extension of the ceramic production section, wastewater effluent limits were exceeded. An interplant wastewater treatment was necessary.

The natural raw material „Kaoline“(porcelain clay) contains chemically bound lead compounds which had to be removed from the wastewater. Especially in wastewater from glaze area there are extremely small particles, which were additionally loaded.

Moreover, it was complicated by the fact that the wastewater was partially diluted by the rainwater.

Solution

For the treatment of such kind of wastewater only two methods were possible: Filtration or treatment in a retention tank with manual precipitation and flocculation.

  • HYDRO Ingenieure for first analysed all different operation wastewaters and executed aiming laboratory tests.
  • Based on the results of analysis and tests, continuous process with reaction tanks and sedimentation tanks was developed.  It works fully automatic and efficiently.
