The Possibility of Nitrogen Removal using the USBF System and the Determination of Its Optimal Detention Time

Morteza Shakeri,; Hossein Ganjidoust; Bita Ayati

Volume 9, Issue 3 , April 2012

  The purpose of this study was to determine the efficiency of the USBFprocess for biological nitrogen removal and achieving the optimal hydraulic retention time according to the maximum nitrogen removal in the system. The synthetic wastewater which was used in this research, was a compound of glucose ...  Read More

Survey on Soft-Wares and Introducing Emission Model for SO2 & H2S in the Ground Level

Nadia Sharifzadeh; Bita Ayati; Hossein Ganjidoust

Volume 8, Issue 4 , July 2011

  Companies need to design engineering software to obtain emission limits before construction and commissioning the plants to control air pollutants. During the design of plants, all emissions should be studied and measured. Since some emissions are lighter or higher than air, there are different methods ...  Read More

Effects of Natural Absorbents on Copper and Lead Removal

Hamid Raftari; Hamid Moazami; Hossein Ganjidoust; Bita Ayati

Volume 8, Issue 3 , April 2011

  Lead and copper are heavy metals that are applied in different industries. Their standard limits in drinking water are 0.05 and 1.3 mg/L, respectively. Since natural absorbents are inexpensive and may be achieved without any cost and they are usually found in abundance in nature, absorption of solute ...  Read More

Investigation of Surfactant Removal Using Moving Bed Biofilm Reactor (MBBR)

Rohaolah Noori; Bita Ayati; Hossein Ganjidoust

Volume 5, Issue 4 , July 2008

  Moving Bed Biofilm Reactor has been taken less attention in treatment of surfactants. In this research with consideration of its advantages and suitable efficiency in industrial wastewater treatment, three 5L-reactors at different retention times were used to investigate the removal efficiency of sodium ...  Read More
