Biodiversity and quantification of functional bacteria in completely autotrophic nitrogen-removal over nitrite (CANON) process.
The research was conducted to investigate the microbial diversity and population with the different concentration of NH(4)(+)-N in a biofilm reactor filled with volcanic filter for completely autotrophic nitrogen-removal over nitrite (CANON) process. The reactor had an excellent performance with the decreasing of NH(4)(+)-N concentration from 400 to 200 mg L(-1) while NH(4)(+)-N removal loading...
متن کاملPerformance of a completely autotrophic nitrogen removal over nitrite process for treating wastewater with different substrates at ambient temperature.
The stability and parameters of a bio-ceramic filter for completely autotrophic nitrogen removal were investigated. The completely autotrophic nitrogen removal over nitrite (CANON) reactor was fed with different concentrations of ammonia (400, 300, and 200 mg N/L) but constant influent ammonia load. The results showed that the CANON system can achieve good treatment performance at ambient tempe...
متن کاملSequentially aerated membrane biofilm reactors for autotrophic nitrogen removal: microbial community composition and dynamics
Membrane-aerated biofilm reactors performing autotrophic nitrogen removal can be successfully applied to treat concentrated nitrogen streams. However, their process performance is seriously hampered by the growth of nitrite oxidizing bacteria (NOB). In this work we document how sequential aeration can bring the rapid and long-term suppression of NOB and the onset of the activity of anaerobic am...
متن کاملAtrazine removal from aqueous solutions using submerged biological aerated filter
Atrazine is widely used in the agriculture as an herbicide. Due to its high mobility, Atrazine leaks into the groundwaters, surface waters, and drinking water wells. Many physical and chemical methods have been suggested for removing Atrazine from aquatic environments. However, these methods are very costly, have many performance problems, produce a lot of toxic intermediates which are very har...
متن کاملdegradation of amoxicillin by bacterial consortium in a submerged biological aerated filter: volumetric removal modeling
background: amoxicillin is widely used as an antibiotic in the modern medicine. due to its chemical structure, polarity, activity level, antibiotic specifications, and environmental sustainability, amoxicillin leaks into the groundwater, surface waters, and drinking water wells. many physical and chemical methods have been suggested for removing amoxicillin from aquatic environments. however, t...
