Sažetak
In former Sisak Steelworks steel pipes were galvanized by hot-dip galvanizing procedure through immersing in molten zinc. Until year 2000, 900.000 tonnes of galvanized pipes were produced. In one phase of the process, preparation of pipes by chemical treatment, around 70.000 m3 of neutralization sludge were generated and disposed of in the landfill site. The physical-chemical properties of sludge were determined using X-ray diffraction technique (XRD), scanning electron microscopy (SEM) equipped with the EDS detector and Brunauer- Emmett-Teller method. Preliminary results indicate that the investigated industrial waste sludge is a non-hazardous with relatively high surface area and can be used for removal of heavy metal ions (CrTOT, Ni2+, Cu2+ and Zn2+) from wastewater.
