Corrigendum to “Start-Up Characteristics of a Granule-Based Anammox UASB Reactor Seeded with Anaerobic Granular Sludge”
The granulation of anammox sludge plays an important role in the high nitrogen removal performance of the anammox reactor. In this study, anaerobic granular sludge was selected as the seeding sludge to start up anammox reactor in order to directly obtain anammox granules. Results showed that the anammox UASB reactor was successfully started up by inoculating anaerobic granular sludge, with subs...
متن کاملStart-up of Anaerobic Ammonium Oxidation (Anammox) from Conventional Return Activated Sludge in Up-flow Anaerobic Sludge Blanket (UASB) Reactor for Autotrophic Nitrogen Removal from Wastewater
A bench-scale up-flow anaerobic sludge blanket (UASB) reactor was applied to start-up the anaerobic ammonium oxidation (Anammox) process from conventional return activated sludge. The reactor was operated for approximately 170 days and was fed synthetic wastewater containing mainly nitrite ) (NO2 − and ammonium ) (NH 4 + as main substrates. After 106 days of operation, the first evidence of Ana...
متن کاملStart-Up Of An Upflow Anaerobic Sludge Blanket Reactor Treating Low-Strength Wastewater Inoculated With Non-Granular Sludge
The upflow anaerobic sludge blanket (UASB) process is known to be energy conservative biotechnology. Its low cost and low skill requirement render it to be a viable technology for reducing organic pollution loads. However, this system is facing a challenge in the treatment of low-strength wastewater especially inoculated with non-granular sludge. This work was performed to emphasis an in-depth ...
متن کاملAnaerobic Digestion of Pulping Wastewater Using Up-flow Anaerobic Sludge Blanket (UASB) Reactor at Mesophilic Condition
Corresponding Author: Randa M. Osman Chemical Engineering and Pilot Plant Department, National Research Centre, Cairo, Egypt Email: [email protected] Abstract: The waste considered for this study was the effluent of the pulping process produced during the manufacture of pulp and paper in the Rakta integrated pulp and paper mill in Alexandria. The pulping process in Rakta mill is condu...
متن کاملDiversity of ammonium-oxidizing bacteria in a granular sludge anaerobic ammonium-oxidizing (anammox) reactor.
The ammonium-oxidizing microbial community was investigated in a granular sludge anaerobic ammonium-oxidizing (anammox) reactor that was operated for about 1 year with high anaerobic ammonium oxidation activity (up to 0.8 kg NH(4)(+)-N m(-3) day(-1)). A Planctomycetales-specific 16S rRNA gene library was constructed to analyse the diversity of the anaerobic ammonium-oxidizing bacteria (AnAOB). ...
