DESIGN CRITERIA FOR WASTEWATER OF RESIDENTIAL COMMUNITY: CASE STUDY FROM JORDAN

Full text

Wastewater characterization is vital for design, operation, collection, treatment, disposal and reuse purposes. It is necessary to assess the strength of wastewater management systems in terms of sustainability. In Jordan, there are no official values of hydraulic and organic loads generated per capita. This study aims to establish design criteria for wastewater of residential community in Jordan. Fuhais wastewater treatment plant was selected as a case study. Annual, monthly, daily and hourly flow variations of wastewater to the plant were studied. Characteristics of the influent and effluent wastewater were determined. The efficiency of the plant was evaluated. Per capita hydraulic load, and the contaminants load were found. One hundred and twenty samples were taken from the inlet and outlet of the plant and analyzed for BOD, COD, TSS, TDS, NH4, TN, pH and P parameters. The results indicated that the average influent concentration of BOD, COD, TSS, TDS, NH4, and P were 598, 1090, 570, 875, and 52.4, 18.7 mg/L respectively. The plant has an excellent efficiency regarding the removal of BOD5, COD, and TSS while it has lower efficiency regarding N and P removal. The average hydraulic load was 97.4 l/c.d. The average contaminants loads were: 58.4, 106.9, 55.8, 7.2, and 1.82 g/c.d for BOD5, COD, TSS, TN and P respectively. There is a significant variation between the values of these parameters compared to those values in other countries.
