From Wastewater Treatment to Sweet Pineapples

by Sulzer Ltd  (Nov. 5, 2014)

In wastewater treatment, ammonia that is removed from sewage used to be discharged directly to the atmosphere. Nowadays, studies have identified that ammonia emissions are of major concern to air quality. This has led to a new way of thinking. Sulzer offers modern closed-air-loop systems for wastewater treatment that transform ammonia into a ...

Stability of alumina, ceria, and silica nanoparticles in municipal wastewater

by IWA Publishing  (Nov. 18, 2014)

Inorganic oxide nanoparticles (NPs) are used in semiconductor manufacturing operations such as wafer chemical–mechanical planarization (CMP). Understanding the stability of NPs in municipal wastewater is essential for the evaluation of the fate of NPs released to municipal wastewater treatment plants (WWTPs). This study aimed to evaluate ...

Implications of nutrient removal and biomass production by native and augmented algal populations at a municipal wastewater treatment plant

by IWA Publishing  (Oct. 20, 2014)

Algal monocultures (Chlorella sorokiniana and Botryococcus braunii) and algal communities native to clarifiers of a wastewater treatment plant were batch cultivated in (1) clarified effluent following a biochemical oxygen demand (BOD) removal reactor post-BOD removal clarified effluent (PBCE), (2) clarified effluent following a nitrification ...

Urban wastewater effluent increases antibiotic resistance gene concentrations in a receiving northern european river

by John Wiley & Sons, Ltd.  (Oct. 20, 2014)

Antibiotic resistant bacteria are an emerging global problem which threatens to undermine important advances in modern medicine. The environment is likely to play an important role in dissemination of antibiotic resistance genes (ARGs) among both environmental and pathogenic bacteria. Wastewater treatment plants (WWTPs) accumulate both chemical ...

Synthetic organic polymer fouling in municipal wastewater reuse reverse osmosis

by IWA Publishing  (Sep. 5, 2014)

A full scale waste water reuse plant suffered from irreversible fouling of the reverse osmosis (RO) membranes. The major suspect of fouling is cationic organic polymers applied in the wastewater sludge treatment. Thus, the purpose of this research is to study the effect of six cationic polymers, applied in the plant, on RO membrane performance. ...

The use of antibacterial activity of ZnO nanoparticles in the treatment of municipal wastewater

by IWA Publishing  (Sep. 17, 2014)

Nanotechnology holds great potential in advanced water and wastewater treatment to improve treatment efficiency. Zinc oxide nanoparticles (ZnO NPs) have received considerable attention due to their unique antibacterial activities toward various microorganisms that are commonly found in the environment. In the present study, ZnO NPs were ...
