Abstract

This paper deals with the removal of heavy metals and nitrate from waste waters by fixed-bed biological reactors. It was found that fixed-bed bioreactors, using immobilized P. aeruginosa cells, are suitable for the simultaneous or separate removal of nitrates and heavy metals from very diluted solutions. The availability of a large amount of plastic waste makes it attractive as a cheap carrier for waste removal. The choice of plastic depends on the intended application: for denitrification PVC is adequate (maximum viability of cells but less stability), for Pu removal PP is better (maximum stability, lessened viability). The plastic based bioreactors are highly competitive with others both in performance and in economy.
