چکیده:

In the future, NO in this time, upgrading of existing wastewater treatment plants (WWTP) will become the more challenging task than erection of wholly new plants, as most of the plants (e.g. necessary in Iran) do exist already. Since some time, MBR technology has been taken into consideration and has been realized as an alternative for WWTP upgrading. This paper gives an overview about some relevant preconditions, basic upgrading concepts south wastewater treatment plants, Isfahan (SWWTPI), with using MBR technology. With using a pilot-scale plant (volume of the bioreactor: 3m3) and raw domestic wastewater. Operation was continued for 120 days. The obtained results were summarized in the following three points. (1) Membrane was able to be continued for the first 90 days without membrane washing and was still stable after the washing. (2) Average removal ratios of BOD, COD, SS, turbidity and total phosphorous were 99, 98.3, 100, 98.4 and 84% respectively. (3) Experiments on simulated inflow fluctuation showed that the system could cope with a short-term fluctuation of inflow without deteriorating membrane performances significantly
