The integrated fixed-film activated sludge membrane bioreactor (IFAS-MBR): comparison with a regular MBR for nutrient removal

The integrated fixed-film activated sludge membrane bioreactor (IFAS-MBR): comparison with a regular MBR for nutrient removal

The IFAS-MBR process is less well explored than the MBBR-MBR configuration. It is of interest to establish the performance of the IFAS-MBR when challenged with a variable influent C/N ratio, since this affects both nutrient removal and the emission of N2O – a highly active greenhouse gas (GHG).

How much does an MBR cost? The relative cost of an MBR vs an SBR

How much does an MBR cost? The relative cost of an MBR vs an SBR

Operational experience at La Center WWTP in Washington, USA indicates that the cost of MBR technology may be lower than that of a conventional biological treatment process, despite the higher energy demand. La Center is a small city in Clark County, Washington, USA, with a population of 3,100. The wastewater treatment works at the town was originally constructed in 1967

Immersed anaerobic MBRs: are they viable?

Immersed anaerobic MBRs: are they viable?

There has been a recent surge of interest in anaerobic MBRs. The technology provides the potential for removing COD with a net energy benefit from the methane generated, albeit without nutrient removal. Interest within academia is evidenced by the publication of five independent reviews of the subject in various learned journals in 2012 alone.
