The objectives of the present study were to improve the quality of drainage water for reuse through the reduction of COD, BOD, TSS, TN, TP, and ammonia, also the removal of odor and detoxification of toxic compounds. The designed system for the treatment of drainage wastewater collected from Bahr El-Baqar drains was performed. The bioactive bacterial strains were applied in this system and followed by the electrocoagulation process. The phyico-chemical and biological parameters were estimated for raw and treated drainage wastewater and compare the quality of treated drainage water according to law 1948. The results acquired pointed out the level of physicochemical items, and the numbers of bacterial indicators in Bahr El-Baqar drainage wastewater have been decreased after biological augmentation treatment after 6, 12 and 24 h. As well, The pH was around 7.2 and 7.4 after biological treatment (table 3). Total suspended solid (TSS) declined from 124 mg/L in Bahr El-Baqar drainage water to 88 mg/L, 75.6 mg/L, 63.2 mg/L after 6, 12 and 24 h contact time, Also, TDS declined from 2410 mg/L in Bahr El-Baqar drainage water to 1710 mg/L, 1470 mg/L, and 1229 mg/L after 6, 12 and 24 h contact time, respectively. The current research concluded that the quality of drainage water was improved after the combined process (biologically and electrocoagulation treatment). The present research, therefore, considered that these technologies are economical and eco-friendly approach to be used in drainage water treatment.
