I want to design a reactor for my research, but first of all i want to know all the aspects related to my research, so can any one explain how we can couple sulfur with nitrate in wastewater treatment plant so that we can easily remove nitrate from waste water...
1. select type of tolerant plants to remove most types of pollutant
2. if you want to use anther types of organisms such as bacteria or algae you need mixed media with two or more species to cooperated these species.
3. you can use algae with bacteria specially some species use nitrate or sulfur in there metabolism.
A good starting point will be working with a plug flow system using Pre-Denitrification with recirculation of Nitrate from the downstream Nitriication. This can be done as MBBR, IFAS or activated sludge. The critical issue will be to have enough NO3-N produced to assure that H2S is oxidized before entering the Nitrification. You could read i.e.:
A novel sulfate reduction, autotrophic denitrification, nitrification integrated (SANI) process for saline wastewater treatment.
Thank you sir @ Kim Helleshoej Soerensen for your valuable suggestions, in fact i was also planned to work on SANI process, but my supervisor did not allow me to work on this. He said that i should work Bacterial aspects to remove sulfur and nitrate from wastewater. so if you have any idea about how SOB or AOB h elps in removing sulfur and nitrate from wastewater, you can share with me.
