Cost and Performance Comparison of a Membrane Bioreactor (MBR) Plant and a Bardenpho Plant for Wastewater Treatment

, 2013
Rotorua District Council constructed a membrane bioreactor (MBR) system to work in parallel with the existing Bardenpho system, to improve the overall capacity and removal efficiency of the wastewater treatment plant.

Performance of hybrid constructed wetland for piggery wastewater treatment [PDF]

, 2013
The environmental impact of the livestock sector in North-East Italy directly affects water (nitrates accumulation and eutrophication). Through the “Nitrate Directive” (91/676/EEC), the EU aims to reduce water pollution caused or induced by nitrates from

Evaluation of the Performance of Vetiveria zizanioides in Removing Nutrients from Wastewater

آب و فاضلاب, 2015
The aim of this study was to evaluate the growth of Vetiveria zizanioides under hydroponic conditions and its efficiency in removing nitrogen and phosphorus compounds from wastewaters. For this purpose, a pilot plant was constructed with a net volume of 60 liters which was intermittently fed for three months with the effluent from a domestic wastewater

Effect of particle size distribution in wastewater on the performance of nutrient removal process

Desalination and Water Treatment, 2012
Abstract The present investigation aims to explore the effect of particle size distribution in wastewater on the performance of sorption denitrification phosphorus removal process (S-DN-P process). The wastewater was obtained from the Wassmansdorf sewage plant in Berlin, which was denoted as the wastewater (WW).

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Initial performance and scalability assessment of a pilot-scale reverse osmosis system for nutrient recovery from source-separated urine

Frontiers in Environmental Science
Human urine is a nutrient-rich resource containing nitrogen, phosphorus, and potassium, yet it continues to be treated as waste. Reverse osmosis (RO) offers a scalable, energy-efficient method for concentrating these nutrients into a liquid fertilizer ...

An analysis of the performance of constructed wetlands in the treatment of domestic wastewater in the Western Cape, South Africa

, 2013
Constructed wetlands (CWs) are being introduced in many parts of the world to treat wastewater. CWs offer several advantages over conventional treatment, most notably to save costs and energy. By contrast there are several limitations associated with the

Cyclic azapeptide CD36 ligand attenuates cardiac injury and reduces long‐chain fatty acid accumulation after myocardial ischemia–reperfusion in mice

FEBS Open Bio, EarlyView.
In a murine model of myocardial ischemia and reperfusion (MI/R), the CD36 azapeptide ligand MPE‐298 reduces cardiac injury and transiently lowers left ventricular long‐chain fatty acids (LCFAs) accumulation 3 h after reperfusion, accompanied by a decrease of oxidative stress and inflammation‐associated genes' expression in the heart and adipose tissue.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Performance Assessment of a UASB Reactor Coupled with Polymeric Filter Media for Nutrient Removal

International Journal on Environmental Sciences
Abstract The aim of this study was to investigate the performance of the UASB reactor coupled with polymeric filter media as a post-treatment unit. The UASB reactor achieved the steady-state condition after 100 days of operation. The COD removal efficiency was 85.54 ± 6.53%, and biogas production (methane 75.5 ± 10.25 and carbon dioxide 25 ± 10.
