A new treatment of wash water for oil fired power plants is proposed which shows a number of advantages with respect to those used at present. The water is preliminarily satured with SO2 and then heavy metals contained (namely: vanadium, iron and nickel) are separated by percolation through a strong cation exchanger in the Na form. The eluted water can be recycled for new washings or air bubbled for discharge. During regeneration of the exchanger (with 3M NaCl solution) vanadium and nickel are separately removed in concentrated form, which may favour recovery in a commercially valuable form. The above treatment fails with water coming from sea water washings.

Abstract
A new treatment of wash water for oil fired power plants is proposed which shows a number of advantages with respect to those used at present. The water is preliminarily satured with SO2 and then heavy metals contained (namely: vanadium, iron and nickel) are separated by percolation through a strong cation exchanger in the Na form. The eluted water can be recycled for new washings or air bubbled for discharge. During regeneration of the exchanger (with 3M NaCl solution) vanadium and nickel are separately removed in concentrated form, which may favour recovery in a commercially valuable form. The above treatment fails with water coming from sea water washings.Pubblicazioni consigliate
