Operating costs for reducing total emission loads of key pollutants in municipal wastewater treatment plants in China
Total emission load reduction of COD, NH4-N, TN, and TP is the key measure in controlling water pollution and eutrophication. Municipal wastewater treatment plants (MWWTPs) are major contributors in lowering energy consumption and reducing pollutant discharge. The flow-based operating costs have not been directly established to relate to costs of pollutant reduction based on an investigation of ...

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 ...

Trace organics removal using three membrane bioreactor configurations: MBR, IFAS-MBR and MBMBR
Seventeen pharmaceutically active compounds and 22 other trace organic pollutants were analysed regularly in the influent and permeate from a semi-real plant treating municipal wastewater. The plant was operated during 29 months with different configurations which basically differed in the type of biomass present in the system. These processes were the integrated fixed-film activated sludge ...

Thermodynamic analysis and assessment of a municipal wastewater treatment system: a field study on sewage treatment
This paper is a field study on thermodynamic analysis and assessment of an actual municipal wastewater treatment facility. The system operation is described and a methodological approach based on the energy and exergy analyses is provided to assess the performance of a complex wastewater treatment system. Since the specific exergy value of the sludge is increased through treatment process, a new ...

Investment and operating costs of municipal wastewater treatment plants in China
The municipal wastewater treatment will continue to be intensified in China due to the economic development and the poor water quality. Within four years, the number of wastewater treatment plants has doubled. Before 2000, mostly plants without nitrogen and phosphorous removal were built. Since Chinese laws require strict effluent qualities, many plants were built with ...

LIMS Key to Quality Data Management in Water Industry
WEFTEC has just wrapped up its 2012 conference – the largest meeting of its kind in North America. The Water Environment Federations’ annual meeting has again delivered comprehensive water quality education and training to thousands of water quality professionals. The leading discussions at WEFTEC this year were centered around emerging research and innovations in the industry. ...

Separating micro pollutants by an innovative membrane process.
Combined adsorption of micro pollutants on activated carbon and membrane filtration of MICRODYN-NADIR has proven an alternative to the established activated carbon/precipitation/sand filtration process. Contamination of the environment by micro pollutants has clearly been proved by now. Due to the high concentration of microorganisms and the contamination by antibiotics coming from animal ...

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 ...

Ultrasound technology in water treatment: Algae control and reduction of biofilm formation
Recent research projects have underlined the potential of ultrasound as a chemical free treatment in water-related applications. This article reviews the use of ultrasound produced by the LG Sonic technology, with a focus on wastewater, irrigation and aquaculture applications. Sound Sound can be described as mechanical energy transmitted by pressure waves in a material medium. Thus, sound ...

The Power of Reclaimed Water
Power generation need not be another source of strain on diminishing freshwater resources. Well-established water reclamation technologies are enabling producers to conserve resources and money. Meeting the needs of a planetary population expected to surpass eight billion people by 2025 is requiring more output from fewer resources. In the case of dwindling supplies of freshwater, the strain ...
