Partial discharge (PD) detection is an important means in the condition-based maintenance of high voltage apparatus including crosslinked polyethylene (XLPE) power cables. In this contribution, we introduce the recent work in Shanghai municipal electric power company on the condition-based maintenance of XLPE power cables. As to how to carry out the PD detection in different circumstances, thre...

The application of anion exchange resins (AERs) has been limited by the critical problem of resin fouling, which increases the volume of the desorption concentrate and decreases treatment efficiency. To date, resin fouling has not been well studied and is poorly understood compared to membrane fouling. To reflect the resin fouling level, a resin fouling index (RFI) was established in this work ...

The non-methane organic compounds (NMOCs) released from municipal solid waste (MSW) landfills impose significant impact on the environment and human health. It is necessary to investigate the fugitive emission of NMOCs from MSW landfills for helping control NMOC emissions and reduce the environmental impacts. This study was focused on the concentration distribution of NMOCs on the operating and...

Hydrocarbons emissions were measured from an aeration tank of a municipal wastewater treatment pilot plant. The collected off-gas samples were characterised for C2–C7 hydrocarbons using GC-FID analytical technique while the total volatile organic compounds (TVOC) were measured using a continuous hydrocarbon gas analyser. Approximately, the estimated emission rates for 1 m3 of wastewater from th...

The study aimed to analyze potential environmental burdens of different waste-to-energy technologies through LCA model. LCA model is developed by SimaPro software by considering Ecoindicator 99 method. Landfill, Incineration, Pyrolysis-Gasification and Anaerobic Digestion are analyzed by considering emission to the atmosphere per unit electricity generation. Results show that, Landfill and Inci...

Los Angeles County's submarine discharge of municipal wastewater off the Palos Verdes Peninsula is the single largest man-related source of trace metals to the marine ecosystem off southern California. The 1974 annual mass emission rates of chromium, copper, and zinc via this discharge were approximately 400, 300, and 850 metric tons, respectively (roughly ten times the corresponding inputs mea...

The aim of this work was to characterize the initial organic content of a selected municipal solid waste incineration (MSWI) bottom ash. This was realized by elemental carbon analysis using pyroanalysis of untreated samples. In addition, MSWI bottom ash extracts obtained by supercritical fluid extraction (SFE) or hot solvent extraction (Soxtec), were analyzed using gas chromatography (GC) coupl...

This study focuses on noise pollution in the Botanical Garden in Curitiba, Paraná, Brazil. Equivalent noise levels (Leq) were measured at 21 points throughout the park, and interviews were conducted with park visitors. Some 47.6% of the measurement sites presented Leq levels over 65dB(A), considered by preventive medicine as the maximum tolerable exposure level without risk of health impairment...

The internal circulating fluidized bed (ICFB) system is characterized with fast combustion, low emission, uniformity of bed temperature and controllability of combustion process. It is a kind of novel clean combustion system, especially for the low-grade fuels, such as municipal solid waste (MSW). The experimental systems of ICFB with and without combustion were designed and set up in this pape...
