Hydroxyapatite Formation in a Single-Stage Anammox-Based Batch Treatment System: Reactor Performance, Phosphorus Recovery, and Microbial Community

Kinetic Characteristics and Microbial Community Analysis by Fish in Anammox Lab-scale Sequencing Batch Reactor

Metagenome of the Microbial Community of Anammox Granules in a Nitritation/Anammox Wastewater Treatment System

We sequenced the metagenome of a granular sludge in a nitritation/anammox bioreactor used for the treatment of ammonium-rich wastewater. Proteobacteria, Planctomycetes, Bacteroidetes, Chloroflexi, Ignavibacteriae, and Acidobacteria were the predominant phyla in the studied bioreactor. Binning of contigs yielded a near-complete genome of the dominant anammox bacterium assigned to the candidate g...

Fast start-up, performance and microbial community in a pilot-scale anammox reactor seeded with exotic mature granules.

The possibility to introduce the exotic anammox sludge to seed the pilot-scale anammox granular reactor and its fast start-up for treating high nitrogen concentration wastewater were evaluated in this study. The reactor was started up successfully in two weeks; in addition, high nitrogen removal was achieved for a long period. Stoichiometry molar ratios of nitrite conversion and nitrate product...

Evaluation of sequencing batch reactor performance for petrochemical wastewater treatment

Sequencing batch reactor (SBR) technology has found many applications in industrial wastewater treatment in recent years. The aim of this study was to determine the optimal time for a cycle of the sequencing batch reactor (SBR) and evaluate the performance of a SBR for petrochemical wastewater treatment in that cycle time. The reactor was operated with a suspended biomass configuration under ae...

A Control System for A Pilot Batch Polymerization Reactor

In this article several control schemes for a pilot scale polymerization reactor are proposed and one of them is selected as the most suitable design. The performances of proposed schemes have been compared through computer simulations. The controllers are PID and Chosen reaction is polymerization of methyl methacrylate which is highly exothermic.
