Fundamentals of the Biological Processes for Nitrogen Removal
2017In this chapter the fundamental aspects involved in biological treatment processes applied for the removal of nitrogen from wastewaters are described. A comprehensive review of the literature is provided including kinetic, microbiological and biochemical aspects of nitrification, denitrification and anammox, as well as key operational parameters ...

Biological nitrogen removal from wastewater
1994A review of the research on the kinetics of nitrification and denitrification is presented including an explanation of reaction engineering models. The results of laboratory scale experiments with high rate nitrification processes are discussed using kinetic results for oxygen limitation as well as for substrate limitation and inhibition.

Biological Removal of Carbon, Nitrogen, and Phosphorus in a Sequencing Batch Reactor
Journal of Environmental Science and Health, Part A, 2003In this research the process performance of enhanced biological phosphorus removal was investigated in a sequencing batch reactor (SBR) having a new operational mode. The SBR system used in this study had simultaneous feeding and decanting conditions. The laboratory scale reactor (10 L) was operated for 392 days.

[Biological nitrogen removal with excess nitrogen uptake by microorganisms].
Huan jing ke xue= Huanjing kexue, 2010The performance of nitrogen removal with sequencing batch reactors were investigated in different pH conditions using simulated municipal wastewater. The experimental results showed that ammonium and nitrate as well as nitrite in R2 (pH controlled at 8.0 +/- 0.2) were 0-1 mg x L(-1) and 8-10 mg x L(-1) respectively, while ammonium and nitrate as well ...

New Processes for Biological Nitrogen Removal
2017The conventional biological nitrogen removal process combining the nitrification and denitrification steps is widely implemented worldwide for the treatment of wastewaters with low to moderate nitrogen concentrations. For highly nitrogen-concentrated streams, the conventional process become limited, mainly due to sizing and operation issues.

Biological Sulfur and Nitrogen Removal from Wastewater
Advanced Materials Research, 2012Based on the summary of biotechnology principles and common processes for the separated desulfurization and denitrogenation in organic wastewater treatment, two novel biotechnologies for simultaneous sulfur and nitrogen removal, which developed from sulfide-dependent denitrification (denitrification with sulfide as electron donor) and sulfate-dependent

Effects of Cd(II) on wastewater biological nitrogen and phosphorus removal
Chemosphere, 2014Short-term and long-term effects of Cd(II) on wastewater biological nitrogen and phosphorus removal were investigated with respect to microorganism abundances, enzyme activities, and polyhydroxyalkanoates (PHAs) and glycogen transformations. Though no obvious effects on wastewater biological nutrient removal were observed after short-term exposure, the
