Polluting metal-organic compounds which are bad for the environment may form if untreated electroplating effluent is released. Numerous methods, including adsorption, chemical precipitation, electrocoagulation, membrane filtration, coagulation and flocculation, ion exchange, improved oxidation process, and bio-recovery, have been documented for treating electroplating wastewater. These techniques offer the ability to extract organic contaminants and separate various harmful elements. When compared to single-treatment systems, the combined use of many techniques has demonstrated improved efficiency in the removal of extensive range of pollutants. Finding the technique that offers the best treatment performance at the lowest cost is the primary problem. An overview of electroplating wastewater treatment technologies is given in this chapter, along with a description of their benefits and limitations. Analysis has been done on the effectiveness of various systems, the types of pollutants eliminated, and a comparison between these systems. It is challenging to determine which treatment technology is the most effective when comparing them because all of the techniques are effective in eliminating some contaminants that the other techniques are unable to recover. Consequently, the treatment’s goal and the contaminants it is intended to address must be taken into consideration while choosing the appropriate treatment technique. In addition, an analysis of the literature has been conducted to assess the costs of various technologies in order to provide a quick overview of the variations in costs.
