Industrial Wastewater Analysis and Treatment for Direct Crop Irrigation
Loading...
Description
Industrial wastewater from metal finishing and the production of electrical and electronic components (40CFR 433, 469) consists of water discharged from facilities that perform several metal finishing operations such as, electroplating, electroless plating, anodizing, coating, chromating, phosphating, coloring, chemical etching, milling as well as the manufacturing of printed circuit boards, semiconductors, electronic crystals, cathode ray tube and luminescent materials. These discharged waters are known to contain toxic metals and other contaminants which are by products of finishing and manufacturing processes and are harmful to the environment. This wastewater requires significant treatment in order to reuse for direct crop irrigation. The main pollutants in this water are high pH, CD, CN, Cr, Cu, Fl, Pb, Sb, Ni, Ag, Zn, and a myriad of organic pollutants. The recommended treatment of this water consists of screening, coagulation/flocculation, sedimentation, filtration, and disinfection along with other methods based on the exact pollutants present. Our team has the privilege of being comprised of students from the University of San Diego as well as the Azrieli College of Engineering in Jerusalem. This work describes the analysis of an Industrial wastewater sample analysis and proposes a suitable treatment process for use as direct crop irrigation.
