Partial denitrification coupled with immobilization of anammox in a continuous upflow reactor

Abstract

Based a continuous upflow reactor stably operating, immobilized anammox coupling with partial denitrification (DEAMOX), was successfully achieved after 94 days operation with a 63.5% accumulation rate of NO2−–N and a 98.4% removal rate of NO3−–N.

Application of natural biodegradable fiber as biofilm medium and carbon source in DEnitrifying AMmonium OXidation (DEAMOX) process for nitrogen removal from wastewater

“…2. NO3to NO2transformation rate (partial-denitrification activity) This result confirming the finding of studies reported the effects of adding polycaprolactone (PCL), as a solid carbon source, for the removal of the NO3 --N produced during anammox process [38].…”

Investigation of growth kinetics and partial denitrification performance in strain Acinetobacter johnsonii under different environmental conditions

“…However, Wang et al . [43] demonstrated that the increase in pH value led to the decrease in the accumulation of nitrite. In the present study, the strain ZY04 could be normally grown in the pH range of 6–10.…”

“…Previous works [8,25,42] have found that an increasing pH promotes the accumulation of nitrite. However, Wang et al [43] demonstrated that the increase in pH value led to the decrease in the accumulation of nitrite. In the present study, the strain ZY04 could be normally grown in the pH range of 6-10.…”

Effects of Ca2+ Concentration on Anaerobic Ammonium Oxidation Reactor Microbial Community Structure

“…Moreover, Ca 2+ precipitated on the particles reduced the effective mass transfer of the sludge [14]. These and other studies underline the importance of understanding cell immobilization in anammox processes, including granulation and biofilm, to improve the treatment performance of the reactor without changing the original microbial community structure [15][16][17][18][19][20][21].…”
