In case of an accidental release of indoor airborne pollutants, it is critical to know information of the pollutant sources. Current inverse modeling concentrates on identifying a single pollutant source or multiple pollutant sources in simplified puff or constant release forms. This investigation proposes an inverse model to precisely identify the multiple pollutant source number, locations an...

In order to alleviate problems such as large fluctuations in grid load caused by the high proportion of renewable energy, circulating fluidized bed (CFB) power plants undertake task rated regulation. This study discussed combustion characteristics a 100 KW CFB boiler during operation process varying loads and analyzes characteristics, regulation rate emissions variation law high- low-rated inte...

The growing consumption of poultry meat has spurred the development meat-processing plants and an associated rise in wastewater generation. Anaerobic digestion is one preferred processes for treating such waste. current push towards biogas upgrading out-of-plant use necessitates new, competitive ways heating digesters. One alternative to electromagnetic microwave radiation (EMR). aim study was ...

A three-dimensional meteorological model and a Lagrangian particle dispersion model are used to study the e€ects of a uniform large-scale wind on the dispersion of a non-reactive pollutant in a coastal region with complex terrain. Simulations are carried out both with and without a background wind. A comparison between model results and measured data (wind and pollutant concentrations) indicate...

This study investigated whether a simple model could scale across watersheds and effectively predict runoff-driven nutrient loading as compared to with more complex process representation. A lumped model, the Spreadsheet Tool for Estimating Pollutant Load (STEPL), was adapted use gridded data (STEPLgrid) applied 112 coastal Atlantic, Gulf, Pacific coasts of contiguous United States (U.S.) estim...

Some relationships between economic development and pollutant discharge have been found to be represented by inverted U-shaped curves, namely the environmental Kuznets curve (EKC), while S-shaped and N-shaped curves have also been found. There are several hard and soft measures to improve water quality in the rivers in Southeast Queensland. Socio-economic conditions related to river water envir...
