Removal Efficiency of Nitrogen, Phosphorus and Heavy Metal by Intermittent Cycle Extended Aeration System from Municipal Wastewater (Yazd-ICEAS)
Introduction: Sequential batch reactor (SBR) is one of the modified biological treatment systems which is able to remove BOD5, Nitrogen, and phosphorus from wastewater. The object of this study is to determine the removal efficiency of nitrogen, phosphorus, and heavy metals from municipal wastewater by the advanced SBR system. Materials and Methods: This descriptive-analytical and cross-sectio...
متن کاملNitrogen removal in a Sequencing Batch Biofilm Reactor: effect of carbon availability and intermittent aeration
This study aimed to investigate the effects of carbon availability and intermittent aeration on nitrogen removal in a Sequencing Batch Biofilm Reactor (SBBR). The percentage of nitrogen removal in the SBBRs operating with dump fill and slow fill with optimum intermittent aeration was quite similar, 75.7% and 69.2%, respectively, indicating that intermittent aeration allowed a considerable energ...

متن کاملNitrogen Removal and N20 Emission in a Full-Scale Domestic Wastewater Treatment Plant with Intermittent Aeration
Nitrous oxide (NzO) is emitted from wastewater treatment processes. It is known as a greenhouse gas that contributes to global warming (over 200 times more per molecule than carbon dioxide) and to the destruction of the ozone layer. It is therefore of great importance to develop technology that can suppress N20 emission. The effects of an anoxic period on NzO emission and nitrogen removal were ...
متن کاملThe Effect of Flux type and Oxygen Blowing on Simultaneous Removal of Phosphorus and Sulfur from Molten Iron
This research was conducted to study the effect of lime based Flux with the composition of CaO-20%CaF2-8%FeO on simultaneous removal of phosphorus and Sulfur from hot metal. The effects of Na2O and oxygen blowing were also studied. The experiments were performed using an induction furnace and hot metal produced in Isfahan Steel Company in the temperature range 1350-1450 ºC...
