Legionella are widely distributed in natural and man-made environments. In these environments, legionella can utilize metabolic products excreted by blue-green algae and other general bacteria, on the other hand they can multiply intracellularly within amoebaebody. The major infection route of legionella is via 1-5 |Lim diameter aerosols which contain the legionella and reach humanalveolar sept...

Thermal power plant is one of the eight high water consumption industries in China, and circulating cooling largest project. Under increasingly severe situation resources measures must be taken to reduce evaporation loss, wind blowing loss pollution discharge natural ventilation tower. Based on comprehensive summary water-saving technology tower, we compared advantages disadvantages various tec...

Industrial circulating cooling water contains a large amount of low-quality energy, which is lost to the environment through towers. It great significance and potential recover waste heat improve energy-saving effects economic efficiency. However, effect common harvesting energy saving devices not significant. Heat pumps have been shown be effective in improving conversion systems, although the...
