The potential adverse effects of concentrated animal feeding operations (CAFO) on the environment are a growing concern. The air quality issues of most concern to CAFO vary but generally include ammonia, hydrogen sulfide, particulate matter, volatile organic compounds, greenhouse gases, and odors. Air pollutants may be regulated by federal and state laws or by nuisance complaints. The United St...

background heat, chemical and organic pollution are three types of environmental pollution, caused by refinery and petrochemical industries. problems caused by hear and chemical pollutants are currently resolved to some extent but organic pollution such as poly aromatic hydrocarbons (pahs) are still considered as important problems of industry and environment. objectives a laboratory study was ...

Nowadays, environmental pollution is constantly increasing, and depollution the most important challenge of 21st century. This paper a review organic pollutants in wastewater that can be removed by photocatalysis process. Also are presented specialized studies demonstrate removal from experimental conditions necessary to obtain high treatment efficiencies. The classes hydrocarbons, halo compoun...

As a general rule, emission factors and emission inventories are fundamental tools for air quality management. Emission estimates are important for developing emission control strategies, determining applicability of permitting and control programs, evaluating the feasibility and the effects of appropriate mitigation strategies, and a number of other related applications by different users, inc...

Wastewaters from various process industries, namely food and agricultural, sugar mill, brewery, milk, vegetable fruit, meat fisheries processing industries their wastewater effluents contain nutrients, organic matter, inorganic, heavy metals, suspended solids, pathogens. The discharges of non-treated enter the nearby aquatic ecosystem (e.g., lakes, rivers) are a significant concern due to prese...
