Total removal of heavy metal from mixed plating rinse wastewater ABSTRACT A mixed plating rinse wastewater containing zinc, hexavalent chromium, trivalent chromium, and cyanide with total dissolved solids
A mixed plating rinse wastewater containing zinc, hexavalent chromium, trivalent chromium, and cyanide with total dissolved solids of 424 mg/1 was treated by a model consisting of a sand filter and ion exchange columns. A strongly acidic cation resin in hydrogen form and a strongly basic anion resin in hydroxide form were used in the columns as cationic and anionic exchangers, respectively. The...
متن کاملkinetic and thermodynamic studies of zinc removal from a metal-plating wastewater using firouzkouh zeolite
introduction with the rapid development of industries such as metal plating facilities, mining, fertilizer producing industries, tanneries and paper industries heavy metals enriched wastewaters are directly or indirectly discharged into the environment. zinc is a trace element that is essential for human health. it is important for the physiological functions of living tissues and regulates man...
متن کاملPlating Wastewater Systems Management
astewaters from all processes w are collected by gravity flow into acid-alkali (rinses), chromate, cyanide, spenttstripping acids, and cleaner sumps. The acid concentrates and cleaner concentrates are gradually fed into chromate and acid-alkali (rinse) sumps, respectively. Cyanide destruction is achieved by oxidation with sodium hypochlorite whereas hexavalent chrome is reduced to trivalent chr...
متن کاملApplication of Clinotptilolite in Removal Ofnickel (II) in Plating Wastewater
The ability of Clinoptilolite powder to adsorb Ni (II) ions from wastewater which was taken from a nickel plating factory was investigated through batch experiments. The Ni (II) adsorption was found to be dependent on mass of adsorbent, contact time, pH value of solution and the speed of agitation. The experimental isotherms data were fitted into Langmuir and Freundlich models. The monolayer ad...
متن کاملZinc, nickel, and cobalt ions removal from aqueous solution and plating plant wastewater by modified Aspergillus flavus biomass: A dataset
The biomass of Aspergillus flavus was modified by calcium chloride to achieve a bioadsorbent for treating nickel, cobalt, and zinc ions from aqueous solutions. The information of pH, bioadsorbent dose, contact time, and temperature effect on the removal efficiency are presented. The data of Freundlich and Langmuir isotherm and pseudo-first-order and pseudo-second-order kinetic models are also d...
