Lead removal from wastewater by cementation utilising a fixed bed of iron spheres.
A lead-ion cementation system was investigated using an iron sphere-packed bed. The extent of lead removal and excess iron consumption in similar conditions to those of lead-bearing wastewater was determined experimentally. Determinations were made for packed spheres of several diameters, beds of different lengths, and different flow conditions. The experimental data were compared by means of rate coefficients and were correlated with empirical equations. The efficiency of lead removal was tested using wastewater from the manufacture of storage batteries.
