Application of magnetic filter method to separate heavy metals from industrial wastewater

Abstract

In this study, the authors have assessed the ability to adsorb heavy metals such as Cd, Cr and Pb by the magnetic particles as PG-M. The study has focused on investigating the influence of such factors as pH, adsorption time and dose of PG-M, determining the optimum values for the construction and operation of magnetic filter model for treating heavy metals in water. The research results have shown that magnetic particles have very good capability of adsorbing heavy metals; using the PG-M particle as adsorbent material in the magnetic filter model provides a high processing performance. The study has constructed the model of magnetic filtration using adsorbent particles as PG-M to seperate heavy metals from wastewater in Danang Mechanical Plating JSC - Hoa Khanh industrial zone with high performance.
