The article delves into certain assessments of industrial wastewater treatment techniques, which utilize aerobic, anaerobic, or a combination of the two. The essay attempts to thoroughly analyse the motives, instruments, and findings of academics as well as researchers. The management of chemical industrial effluent from a structure, as well as the construction of a chemical plant next to a rubber shoe factory, is investigated. The wastewater from the different plants is discharged into the municipal sewage system. The sewage released from the buildings, and also the construction chemical plant, is considerably contaminated with organic chemicals, as per the data. The mean biological oxygen demand (BOD) was 149.8mgO2/l and the chemical oxygen demand (COD) was 2911.8mgO2/l, accordingly. Phenol values of up to 0.28 mg/litter were found. Chemical treatment with ferric chloride and lime was effective, and the effluent had a characteristic that was within Egyptian permitted limits. At the other facility, domestic wastewater is mixed with industrial wastewater to decrease the load, i.e., organic. The BOD and COD values after mixing were 2614.8 and 5238.8 mgO2/litter, respectively. The average phenol concentration is 0.48 mg/litter. As a consequence, the chemicals industrial wastewater's properties determine whatever treatment approach to employ. The engineering development of each treatments structure is predicated on laboratory results.
