The plating industry is one of the main toxic chemicals consumers, which uses various chemicals, including solvents, acids, bases, cleansers, sophisticated organic ingredients, and metal salts of cadmium, nickel and chromium. Due to the growing production of industrial waste in spite of actions related to these wastes’ management, no comprehensive pattern was introduced at different levels. Thi...

Membrane electrolysis (ME) is the only commercial technology using ion-exchange membranes for chromic acid recycling and recovery. On one hand, the technology has a number of promising advantages, but on the other hand, it has not yet gained common acceptance probably due to a lack of operation stability and efficiency. Published results of the research can be divided into three categories: lab...

Effluent from electroplating industry involved in copper plating and other metal polishing work contain various heavy metal(Cu, Fe, Ni, Pb, Mn and Zn) which have severe adverse effect on health . The present work analyzes heavy metal present in plating shops for a period of one year. Highest copper metal concentration (27.60mg/L) was observed during post monsoon at site AB-5, least copper metal...

aims: chromium is one of the most important metallic pollutants in plating industry wastewater. this toxic metal is a serious threat to human health and to the environment due to its cumulative effects and non-degradability. this research intended to study the effects of ph, contact time, and voltage on the degree of chromium removal from wastewater of plating industry by using the electrocoagu...

Capillary zone electrophoresis was used in the analysis of anions and cations in electroless plating bath samples. Examples described in this application note include the analysis of inorganic and organic anions in nickel-plating baths, cations in nickel-iron-cobalt-plating baths and metal-EDTA complexes in plating bath waste. Sample preparation was minimal, consisting merely of diluting the sa...

aims: textile industries are among the manufactures which produce the highly polluted waste water. the purpose of this research was to evaluate the effect of vermifiltration on cod and color removal from textile waste water. materials & methods: this experimental research was performed march to august 2014 in one of the textile factories of kashan region, iran. the glass cubic kits with- withou...

This report presents the results of PRCs waste audit study for the metal finishing industry. The study was conducted to identify opportunities for waste reduction available to the metal finishing industry and to develop a generic audit protocol that can be used by metal finishers to assess their own waste reduction opportunities. The study emphasized technologies available to smalland medium-si...
