Removal of divalent metal mixtures from water by yeast using crossflow microfiltration
Özet
The removal of heavy metal ions, Ni2+, CU2+ and Pb2+ using yeast cells as carriers in a crossflow microfiltration Is studied. The metal ion rejection decreases if yeast cell concentration is greater than similar to 2 g/l as a result as cell aggregation. The binding affinity of the metals to yeast cell is Pb2+ > Cu2+ > Ni2+ which is also reflected in the metal ion rejection under identical process conditions. Due to the formation of yeast cell flocks in the presence of Pb2+, permeate flux is also higher for this metal. The presence of NaCl decreases both rejection and permeate flux for Ni2+ and Cu2+ but not for Pb2+. When binary or ternary metal mixtures are used, the rejections of the individual metals is reduced except that of Pb2+. The pseudo-gel concentration is unaffected by the presence of metal ions.
