Abstract

Heavy metals are one of the most serious environmental pollutants in water; they caused serious damage to animals and human lives. The electroplating industry generates a high portion of the effluents, which are highly toxic and can be considered a dangerous material pollutant. The current investigation contracts to remove Cu (II) from electroplating industrial wastewater as well as eliminate environmental impact of that effluent. The wastewater was characterized by low pH (3.2), high chemical oxygen demand (COD, 650), ammonia (4.72), total suspended solids (TSS, 312), TKN (13), TDS (3500) and Cu (1200). As a result, the layout and functionality of treatment plants require careful handling of the wastewater generated by the electroplating industry. Traditional treatment processes for that waste remain ineffective in meeting the necessary boundaries of the national regulatory standard. Meanwhile, such wastewater contains resistant and toxic compounds that require extensive work. The present work used Fenton's reactions and/or meso-active carbon for the treatment of the final electroplating effluent and removal of Cu as a substitute for traditional treatment procedures. The prepared Meso active carbon was characterized by different techniques as XRD, BET-surface area and FT-IR. The obtained results reveal that, cu removal present 97%, BOD 98%, COD 82%, TSS 78%, TDS 54%, TS 40%, TKN 87%, ammonia 97%. The results indicated the good quality of the treated effluent with Permissible values for wastewater and can be reused for irrigation wood trees.
