Simultaneous treatment of phenolic and chromic waste waters

Abstract

"Sartid 1913" d.d. Beli limovi - Šabac operates Tin Plate Manufacturing Plant within which Waste Water Treatment Plant has been designed for treating waste waters coming from the Plating process consists of the following sections. 1. Alkali Section where both concentrated and dilated waste waters occur; 2. Pickling Section where both concentrated and diluted sour waters occur; 3. Electrolytic Tin Plating Section containing phenol waters; 4. Passivation Section where both concentrated and diluted chromic waters occur. Waters from Section 7 and 2 are treated by neutralization, waters from Section 3 are treated by oxidation with Fenton reagent, and waters from Section 4 are treated by reduction process. The process of waste water treatment is continuous. Keywords: Phenolic waste water Chromic waste water Tinplate Fenton reagent trans, trans - Muconic acid .
