    eavy metals in effluent are serious problem of concern during treatment process to be efficient. Electroplating wastewater contains heavy metals such as nickel, chromium, zinc and iron after discharged from treatment unit. These heavy metals above limits can cause adverse effect on the humans and Size: KB. Removal of heavy metals from industrial wastewater is of primary importance because they are not only causing contamination of water bodies and are also toxic to many life forms. Industrial processes generate wastewater containing heavy metal contaminants. Since most of heavy metals are non degradable into nontoxic end products, theirFile Size: KB.
