Cycle-time determination and process control of sequencing batch membrane bioreactors
In this paper a method to determine the cycle time for sequencing batch membrane bioreactors (SBMBRs) is introduced. One of the advantages of SBMBRs is the simplicity of adapting them to varying wastewater composition. The benefit of this flexibility can only be fully utilised if the cycle times are optimised for the specific inlet load conditions. This requires either proactive and ongoing ...

Influence of dissolved oxygen concentration on the start-up of the anammox-based process: ELAN®
The anammox-based process ELAN® was started-up in two different sequencing batch reactor (SBR) pilot plant reactors treating municipal anaerobic digester supernatant. The main difference in the operation of both reactors was the dissolved oxygen (DO) concentration in the bulk liquid. SBR-1 was started at a DO value of 0.4 mg O2/L whereas SBR-2 was started at DO values of 3.0 mg O2/L. ...

Foam control in a food processing wastewater SBR treatment unit case study
Cost-Effective Biological Foam Control Using Microcat DF Defoamer The sequencing batch reactor activated sludge plant (SBR) operating on a potato processing wastewater is experiencing a severe foaming episode. The foam can reach three inches in depth reducing the efficiency of the surface aerators and causing odors. The treatment system consists of primary filtration and an SBR aeration ...

Rapid quantification of polyhydroxyalkanoates (PHA) concentration in activated sludge with the fluorescent dye Nile blue A
The present study was conducted (1) to develop a rapid quantification method of polyhydroxyalkanoates (PHA) concentration in activated sludge by Nile blue A staining and fluorescence measurement and (2) to perform on-line monitoring of PHA concentrations in activated sludge. Activated sludge samples collected from laboratory scale sequencing batch reactors and full-scale wastewater treatment ...
