Biofilms in the Removal of VOCs and Foul Odors
نویسنده
چکیده
Volatile Organic Compounds (VOCs) are widely used in many industries such as printing, petrochemicals, plastics, refrigerant, electronics, and paint manufacturing. (Babu and Raghuvanshi, 2004). However, large quantities of VOCs are released into the air, soil and groundwater because of occasional accidents and the absence of proper treatment technologies. Most VOCs are toxic and carcinogenic substances. Loss of these substances to the ambient air may have an adverse impact on air quality and thus endanger public health. Therefore, it is very important to develop effective means of removing these compounds to preserve human health and the environment.

متن کاملOzonation of Odorous Compounds in Gases Emitted from Rubber Processing Industries
This study aimed at the removal of odorous compounds in gases emitted from rubber processing industries. Simulated odorous gas for test was prepared by mixing fresh air and an odorous gas drawn from an oven in which a sample of rubber powder was kept either at 160°C (for a thermal plastic rubber) or 200°C (for a thermal setting rubber). The prepared odorous gas was then premixed with a definite...
