Operation of a full-scale pumped flow biofilm reactor (PFBR) under two aeration regimes
A novel technology suitable for centralised and decentralised wastewater treatment has been developed, extensively tested at laboratory-scale, and trialled at a number of sites for populations ranging from 15 to 400 population equivalents (PE). The two-reactor-tank pumped flow biofilm reactor (PFBR) is characterised by: (i) its simple construction; (ii) its ease of operation and maintenance; ...

Comparative analysis of DNA-based microbial community composition and substrate utilisation patterns of activated sludge microorganisms from wastewater treatment plants operated under different conditions
In this study, the microbial community structure and carbon source utilisation profile of activated sludge samples collected from full-scale municipal wastewater treatment plants (WWTPs) operated under different conditions were characterised and compared, respectively, using terminal-restriction fragment length polymorphism (T-RFLP) analysis and Biolog assay. Samples were collected from each ...

Full scale municipal implementations of the Agar IFAS process for municipal wastewater treatment
Wastewater treatment plant retrofits worldwide are motivated by two main developments: a. Changes in effluent quality regulations, either to more stringent BOD/TSS requirements, or to include nutrient (N and P) removal b. Increase in flows to existing plants, due to either population growth or to expansion of sewerage systems One process capable of giving a cost-effective solution for these ...
