3356m3\/d<\/li>\n<li>Membrane area: 34848m2<\/li>\n<\/ul>\n<h2>Project background<\/h2>\n<p>Electroplating wastewater has high salinity and a large volume and contains heavy metal ions and complexes, making it a typical difficult-to-treat industrial wastewater.<\/p>\n<p>The industrial park requires increasing the water reuse rate while controlling the volume of discharged concentrate and the amount of hazardous waste generated.<\/p>\n<p>The project uses electrodialysis (ED) as the core unit for desalination and concentration, creating conditions for subsequent reuse and reduction processes.<\/p>\n<h2>Process route<\/h2>\n<ul>\n<li>Conventional electrodialysis (ED) is the main process, with a large number of membrane stacks configured in parallel according to the treatment capacity.<\/li>\n<li>Under the electric field, salts migrate to the concentrate compartment, and the product water from the diluate compartment is returned to production or the circulating system as reuse water.<\/li>\n<li>The pretreatment stage controls hardness, heavy metals, and organic matter to reduce the risk of membrane fouling and scaling.<\/li>\n<li>The concentrate enters subsequent evaporation or advanced treatment units, forming a closed process loop of reuse and reduction.<\/li>\n<\/ul>\n<h2>Configuration scale<\/h2>\n<ul>\n<li>Treatment capacity: 3356
