Saving And Minimization Of Contaminants By Recovering Cations And Anions And Water Recycling

摘要

The European Community have directives such as RoHS (Rectriction of Hazardous Substances); WEEE (Waste, Electrical And Electronic Equipment); and ELV (End of Life Vehicle).Minimization for contaminants for applying in chemical and electrolytic treatments and oil and grease separation in degreasing processes: Interchange columns for retarded retention of ionic cations and metallic anions. Hydrofugues miscivility separation of water no contaminated by volatile organic compounds (VOC's). Membrane-filtering by permeate or nanofiltering device to retain cations and anions from a tertiary process to obtain better quality water and refused water to be reused for washing or secondary tasks. Recover of rinsing water from nickel, hard chrome and decorative chrome processes.
