Activation energy can be calculated from the equation (3) and was used as an identification of temperature influence on Anammox as well as other biological processes. According to Equation 1 and Equation 2, in order to treat ammonia rich effluents with the anammox process, half of the incoming nitrogen needs to be oxidized to nitrite. The latter process is called nitritation (Equation 3), and it is performed by the ammonia oxidizing bacteria (AOB). Kuenenia stuttgartiensis’ can be examined by simulating microbial growth of these two anammox bacteria using the Monod equation. As shown in Fig. 2, ‘Ca.

In this study, the abundance and biodiversity of anammox bacteria were investigated in both saline and freshwater full-scale sewage treatment plants (STPs). In the following equation, the relevant parameters were cited from an Anammox reaction equation , and the MNPR (mLN 2-N/L·d) was associated with active biomass (): where is the decay coefficient (d −1), is the maximum growth rate (d −1), is the concentration of Anammox organisms (mgCOD L −1), is the Anammox growth yield (mg COD mg NH 4-N −1), and is the maximum specific nitrogen gas production … 2008-05-01 2015-07-15 equation in which a reaction rate exhibits an exponential increase with temperature. For this study, a cardinal temperature equation with inflection25) for growth of anammox bacteria was incorporated into a mathematical model24) for the anammox process. The modified model was used for predicting nitrogen removal and bacterial Anammox bacteria use nitrite as an electron acceptor to oxidize ammonium into nitrogen, and nitrate is formed in the process of the reaction . According to the stoichiometric formula, 0.26 mol nitrate is produced when 1 mol ammonium and 1.32 mol nitrite are consumed in the process of anammox .

anammox bacteria use nitrite as an electron acceptor instead of nitrate in the anammox reaction. In 1998, Strous et al.  used a mass balance approach to calcula te the Anammox is an autotrophic nitrogen removal process that produces nitrogen gas from nitrite and ammonium without the need for organic carbon sources (Equation ) (Strous et al.

Revised equations for calculating the anammox and denitrification rates and the N 2 production rate in the presence of DNRA Introducing DNRA to an environment with both anammox and denitrification contribution to the N 2 production, may lead to substantial overestimation of denitrification and underestimation of anammox as a factor of F A (Fig. 1 ). Anaerobic ammonium oxidation (anammox) is a recently discovered microbial pathway and a cost-effective way to remove ammonium from wastewater. Anammox bacteria have been described as obligate chemolithoautotrophs.

(1) From these plots, apparent activation energies of anammox bacteria were calculated using the Arrhenius equation for each temperature range. The apparent activation energy in the temperature range from 22 to 28 °C was calculated as 93 kJ mol −1 , and that in the range from 28 to 37 °C was calculated as 33 kJ mol −1 ( Table 1 ). Anaerobic ammonium oxidation (ANAMMOX) is a well-known microbial process that can remove ammonium and nitrite simultaneously (Mulder et al., 1995; Strous et al., 1998). Equation (1) shows the overall pathway for the removal of these contaminants by ANAMMOX bacteria under anaerobic conditions (Sliekers et al., 2002). Application of INTRODUCTIONAnaerobic ammonium oxidation (Anammox) is carried out by different bacteria related to Planctomycetes, according to the following stoichiometric equation: 1NH + 4 + 1.32NO − 2 + 0.066HCO − 3 + 0.13H + → +1.02N 2 + 0.26NO − 3 + 0.066CH 2 O 0.5 N 0.15 + 2.03H 2 O( 1 )The decay coefficient is one of the main variables in the mathematical modeling that is applied to biological wastewater processes.
