Effect of Fe3+ on the nutrient removal performance and microbial community in a biofilm system. [PDF]
Front Microbiol, 2023 In this study, the influence of Fe3+ on N removal, microbial assembly, and species interactions in a biofilm system was determined. The results showed that maximum efficiencies of ammonia nitrogen (NH4+-N), total nitrogen (TN), phosphorus (P), and chemical oxygen demand (COD) removal were achieved using 10 mg/L Fe3+, reaching values of 100, 78.85, 100,

Genome-Resolved Metagenomics of a Photosynthetic Bioreactor Performing Biological Nutrient Removal
Microbiology Resource Announcements, 2021 Enhanced biological phosphorus removal (EBPR) is an economically and environmentally significant wastewater treatment process for removing excess phosphorus by harnessing the metabolic physiologies of enriched microbial communities. We present a genome-resolved metagenomic data set consisting of 86 metagenome-assembled genome sequences from a ...

The effect of PO43--P concentration on sludge settleability and nutrients removal performance
Water Science and Technology, 2022 Abstract In order to explore the effect of influent -P concentration on the relationship of phosphorus remove performance and sludge settleability, three sequencing batch reactors (SBRs) operated as anaerobic/aerobic mode were used to treat wastewater with different -P concentrations (same COD), and the organic loading rate (OLR) was ...

Water Science and Technology, 2001 Stringent effluent quality guidelines are progressively implemented in coastal and sensitive areas in Australia. Biological Nutrient Removal (BNR) plants are becoming a standard often including a tertiary treatment for disinfection. The BNR plant in Noosa - Queensland is designed to produce a treated effluent with less than 5 mg/l of BOD5, 5 mg/l of ...

Influence of vegetation type and temperature on the performance of constructed wetlands for nutrient removal [PDF]
Water Science and Technology, 2017 Abstract In this study, the influence of vegetation type and environmental temperature on performance of constructed wetlands (CWs) was investigated. Results of vegetation types indicated that the removal of most nutrients in polyculture was greater than those in monoculture and unplanted control. The greatest removal percentages of NH4+-
