Introduction

Fluoranthene is a polycyclic aromatic hydrocarbon (PAH) with molecular formula C 16 H 10. Its name derives from the fluorescence that presents the UV light. Like the other HAP is produced during combustion of some organic products. In this context, water is both a right and a responsibility, and has economic value, social and environmental. Every citizen, every company has to realize that the quality fresh water is a natural resource, dwindling surface and underground, necessary not only for economic development, but essential to support any form of life in nature. There is doubt that the industry is the engine of economic growth and, therefore, key social progress. However, too often the need to maximize excludes production process of planning the third leg of progress, environmental protection. Appropriate treatment of industrial wastewater and its subsequent reuse for multiple uses contributes to sustainable water consumption and regeneration environmental public water and sea and its ecosystems. Not to mention the water quality is a critical raw material for the industry (Vaughn, 2009, p. 23-27).

Discussion

The most common treatment that can be proposed is an aerobic system called the activated sludge process. This waste water treatment process is based on the recirculation of a biomass composed of microorganisms that are able to absorb and adsorb the organic matter carried in the wastewater. (Droste, 1997, 156-162) Anaerobic digestion is similar to landfill disposal but differs in two ways. First, it controls the process, which means all the gas produced during degradation is used. Second, the process is complete within a few weeks. Anaerobic digestion is conducted in an enclosed and closely controlled reactor. The different types of anaerobic digestion systems are leach-bed process, multistage wet digestion, dry continuous digestion, dry batch digestion and wet continuous digestion (Cech, 2005, 56-61). Fluoranthene is a polycyclic aromatic hydrocarbon structurally derived from naphthalene bound to benzene by two single bonds forming therewith a pentagonal ring. It is therefore a non-HAP said alternating isomer structural pyrene, who itself is an alternating PAH (Tchobanoglous, et al., 2003, p. 87-95).

Environmental Exposure and Fate

Fluoranthene is produced by incomplete burning of organic compounds. In general, fluoranthene's occur in exhaust from gasoline and diesel engines, smoke from open burning, industrial smoke emissions, coal tar and pitch, coke oven emissions, asphalt, creosote, mineral oil, soot, tobacco and its smoke, and charcoal broiled foods. Benzo(a)anthracene is found in exhaust fumes, tobacco smoke, general soot and smoke, coal tar and pitch, amino acid, fatty acid, waxes, solvents, mineral oil, and creosote. Benzo(b)fluoranthene is also in exhaust, tobacco and its smoke, tar, soot, and amino and fatty acid pyrolysis. Benzo(j)fluoranthene is in exhaust, tobacco smoke, crude and used motor oil, and coal ...
