STUDY ON THE USED OF CHLORINR COMPOUNDS TO COD REMOVAL IN WASTEWATER OF IMC PHARMACEUTICAL FACTORY IN QUANG MINH INDUSTRIAL ZONE – ME LINH – HA NOI

Abstract

Study treatment is performed with wastewater from IMC Pharmaceutical Factory, located in Quang Minh industrial zone - Me Linh – Ha noi, mainly products of the plant are food supplements, traditional medicines. In the process of production, the plant has discharged a large amount of wastewater containing active pharmaceutical ingredients (APIs). Most of APIs are non-biodegradable and The main component made up the characteristic pollution is COD and color high. The Chlorine compounds is used to removal COD and color in pharmaceutical wastewater, include chemistry Cl₂, ClO₂ and FeCl₃. The study results showed that the high removal efficiency of COD and color,  removal efficiency of COD and color were 79.5% and 95.6% respectively at the point of  FeCl₃ = 0.4 g/L, Cl₂ = 0.083 g/L, ClO₂ = 0.158 g/L.
