LAB, Waste Water Treatment
Water Treatment units are offered to treat bleeds from GraniLAB™ scrubbers.
All the residues undergo intense acid leaching in the scrubber acid loop.
The heavy metals which can be mobilized are stabilized and the deconcentration bleed is the filtered in an acid medium, in order to recover a stabilized residue.
The filtrate is then heated to precipitate the heavy metals and filtered to obtain a cake. Clear water is finally treated in sand and carbon filters to eliminate final traces of some heavy metals.
