Removal of Ni and Cr from the contaminated water, about 5-10 m³/h
The company Sasol Solvents Germany GmbH with the plant in Moers operates a production facility in which the Ni-/Cr containing water is obtained. The elements Ni and Cr are removed from this water.
Concept:
In one of the production plants, the larger quantity of selective exchange resin accumulates which is at present supplied at the time of disposal. This resin still has a residual capacity of 50% and now used for Ni-/Cr- elements. For this purpose, 2 ion exchange tanks should be installed, which are operated in series. The first container is used as a working exchanger, the second container as a "police exchanger". After exhaustion of the working exchanger they are "regenerated" and the police exchanger is converted to a new working exchanger which is operated alone for the duration of the regeneration. After regeneration, the fresh regenerated police exchanger is switched on again in series of work exchanger.
Regeneration:
As it is "resin waste", this is removed as per the load from the ion exchanger and is then filled with fresh "resin waste" (50% of remaining capacity).
