SCR and FGD are making a significant contribution to the control of NOx and SO2 emissions from coal-fired generating units. These technologies are expected to contribute to further reductions in pollutant emissions in response to proposed emission reduction rules. The ability of these technologies to make significant contributions to pollution reduction in a cost-effective manner depends, in pa...

Effects of climatic changes, progressing urbanization and improved environmental controls on the simulated urban stormwater quality in a Northern Sweden community were studied. Future scenarios accounting for those changes were developed and their effects simulated with the Storm Water Management Model (SWMM). It was observed that the simulated stormwater quality was highly sensitive to the sce...

Lanzhou is one of the major industrial cities in northwest China, the capital of Gansu Province, and located at a northwest-to-southeast oriented valley basin with elevation about 1500-1600-m. Due to topographic and meteorological characteristics, Lanzhou is one of the most polluted cities in China. Meteorological conditions (low winds, stable stratification especially inversion), pollutant sou...

For the performance evaluation of coal enterprises energy conservation and reduction of pollutant emission, a new attitude index group decision-making method is proposed based on trapezoidal fuzzy numbers. Under the condition in which the information of attributes weights and decision maker weights is entirely, the attitude index is introduced firstly. By solving the fuzzy object programming fo...

in this work, ferric coagulation and acid cracking as olive mill wastewater (omw) pretreatments during photocatalysis process were compared in batch recirculation reactor. as ferric ions influence, ferric coagulation has preference over acid cracking. ferric ions influence on intensification of penolic components absorption on tio2 surfacein initial and oxidize organic pollutant during photocat...
