摘要：

Biosorption of zinc by sludge micro-organisms obtained from different steps of a conventional SWT plant has been studied. The best types of activated sludge for the process were found to be thickened, anaerobic and dewatered sludge giving up to 90-98% of metal elimination when working at initial zinc concentration lower than 50 mg/l. A relationship between pH and conditional stability constant has been found.
