biological treatment of ammonia in wastewaters

Biological Treatment Of Ammonia In Wastewaters

Ammonia can be separated from wastewater in various ways, which can be classified as either physical, chemical or biological. Physical methods includes: adsorption, vacuum distillation, air stripping, and membrane separation. Chemical methods includes ion exchange and biological approaches biologically oxidize the ammonia to nitrate and nitrite.

Another type of biological treatment is sequencing batch reactors (SBRs) that involve multi-step biological processes to treat high nitrogen wastewaters. More traditional biological treatment methods, such as activated sludge, can be used for wastewater with a low ammonia concentration (<30 to 40 mg/L ammonia). Discharge to POTW.

Biological Removal of Nitrogen from Wastewater | SpringerLink

Abstract. The removal of ammonia from wastewater has become a worldwide emerging concern because ammonia is toxic to aquatic species and causes eutrophication in natural water environments (Tchobanoglous et al. 2003).Nitrogen compounds in wastewater can only be effectively removed by biological approaches (EPA 1993; Zhu et al. 2007a,b).Based on the microbial nitrogen cycle and the metabolism

review: anaerobic ammonium oxidation for treatment

Review: Anaerobic ammonium oxidation for treatment

INTRODUCTION. Ammonia in wastewaters if discharged inappropriately has adverse environmental effects to aquatic systems. It is toxic to living organisms and causes eutrophication in water bodies (Wu et al., 2008).Thus, both physico-chemical and biological technologies have been applied in elimination of ammonium from wastewaters for a long period (Bonmat铆 and Flotats, 2002; Sugiyama et al

Application of zeolites for biological treatment processes

Zeolite utilization in aerobic processes for organic removal from wastewaters. The use of zeolites in biological wastewater treatments has been also extended to aerobic processes. In this case, zeolite is used to help to improve the nitrogen removal and the settling properties of sludge, as well as the phosphorous removal through P-accumulating

Biological treatment in wastewater treatment plants (WWTPs) is a source of nitrogen oxides (N2O, NO and NO2) emitted to the atmosphere. Aerobic ammonia-oxidising bacteria (AOB) have been suggested to be the main source of these emissions.

MX345406B - Optimized nutrient removal from wastewater

Methods and systems are provided for reducing ammonia partially by a denitrification process. A stream containing ammonia is contacted with oxygen to form a first product stream in low dissolved oxygen conditions. The ratio of oxygen to nitrogen is about 2.28 g O2/g N-NH3 (2.28 grams of oxygen per gram of nitrogen in ammonia) or less. The first product stream is then exposed to organic matter
