Title: WASTEWATER-PROCESSING METHOD
Abstract:
The invention relates to a wastewater-processing method for precipitating Ni and Al out of two different flows. Ni is precipitated out of an inorganic first wastewater flow, which also contains Al, in order to produce an Ni-free inorganic first wastewater flow. The Ni-free inorganic first wastewater flow is then led into an Al-containing organic second wastewater flow in order to produce a third wastewater flow. Al is then precipitated in the third wastewater flow.
