Metallurgy


This filtration is used to separate different metals. To this end, One of the metals gets dissolved and can then be removed during the filtration with the filtrate, while the other metal, that is not dissolved, remains in the filter cake. To remove the residues of the dissolved metal from the filter cake, this is washed after filtration, blown dry and be squeezed.


Metallurgical industries have challenging process water conditions and the streams tend to be large containing fine particles. These kinds of waters are difficult to treat with traditional methods such as settling, because the fine particles do not settle by gravity efficiently. Therefore a method for high-rate filtration and a small footprint is crucial for increasing the water re-circulation rate at a plant, as well as the benefits of having clear water for process.
