Abstract

The main objective of this research work was to evaluate the performance evaluation (removal efficiency) of the Suez Bay industrial wastewater treatment plant (SBIWTP) at the Ataqa region with respect to the removal of chemical and microbial pollutants to meet the prerequisite of Egyptian suggestions Law number 4 of 1994. Effluent water and sewage sludge from SBIWTP are suggested for agricultural usage. Therefore, the effluent waters have been evaluated for irrigation purposes relying on FAO regulations as well as the risk of heavy and trace elements was estimated in sewage sludge on the environment. Eighteen samples were gathered from influent and effluent waters during the 9 months of 2018. Samples were analyzed in terms of chemical, physical, and microbial parameters. Sewage sludge from SBIWTP was analyzed in accordance with the extraction method proposed by the Community Bureau of Reference (BCR). The most significant findings in this study, the influent wastewater discharged to the plant was highly contaminated with color, TSS, turbidity, NH3, COD, BOD, oil & grease, phenol, nitrate and phosphate levels. The efficiency of removal was estimated during 9 months to be 75%, 87%, 67%, 93%, 89%, 92%, 14%, 66%, 76%, and 74%, respectively. Relying on Egyptian Law, SBIWTP confirmed good performance for all contaminated parameters except for color. Concerning to FAO guidelines, it noticed that the effluent water can be used with slight to moderate restriction for eating non-cooked medium tolerant plants in coarse soils with good permeability. The trace and heavy elements in sewage sludge demonstrated safe to low risk on the environment. Further examinations ought to be carried out especially to study the reuse of Suez Bay industrial wastewater treatment plant (SBIWTP) effluent and sludge‎‎‎‎‎.
