Eco-technological Treatment of Hattar Industrial Wastewater in Constructed Wetland through Different Arrangement of Anaerobic Conditions

Hattar Industrial Estate discharged effluent without any treatment into Jarikas drain. Present study was an endeavor to evaluated the contaminant in Hattar Industrial wastewater by appraising the physico-chemical and heavy metal analysis which showed that pH, COD, Cu, Ni, As and Fe were above the standards for industrial liquor discharge. Treatment through natural processes like anaerobic digestion and constructed wetland more appealing option for in the context. Different arrangement in the units affect the treatment efficiency and quality of effluent. Current study evaluated the different arrangements of natural processes, in T1 ABR Post-treated in Constructed Wetland whereas; T2 ABR Pretreated in Constructed Wetland. Compared the effluent of both the treatments with permissible limits for irrigation and observed that most of the water quality parameters were under the permissible limits in T2 as compared to T1. Also higher percentage removal conducted in T2 as rivaled with T1.
