Authors: Lavinia Lupa, A. Iovi, P. Negrea, Adina Negrea, Ileana Radu


Abstract:

In this paper we made studies regarding the heavymetals removal from residual waters resulted from thermal zinc coating. In the view of the optimum conditions establishment of heavymetals removal from the residual waters we used different neutralisation agents (sodium hydroxide solution 30%, sodium carbonates 10%, calcium oxide, mixture of sodium hydroxide and sodium carbonates, and sodium hydroxide with aeration).


Keywords: waste waters, heavy metal removal, neutralisation
