Volatile Organic Compounds Removal Methods: A Review
Volatile Organic Compounds (VOCs) are among the most toxic chemicals which are detrimental to humans and environment. There is a significant need of fully satisfactory method for removal of VOCs. There are several methods including physical, chemical and biological treatments available to remove VOCs by either recovery or destruction. The aim of the present study is to summarize the available m...
متن کاملHydrogen sulfide and organic compounds removal in municipal wastewater using ferrate (VI) and ultraviolet radiation
Background: In this study, ferrate (VI) and ultraviolet (UV) radiation were employed to remove hydrogen sulfide from municipal wastewater resulting in a reduction in chemical oxygen demand (COD). Although ferrate (VI) and UV have been used individually for the removal of a few pollutants from urban and industrial wastewater, there exists no study to investigate the effectiveness of si...
متن کاملCatalytic Removal of Volatile Organic Compounds
The degradation of air quality by the release of volatile organic compounds (VOCs) into the air particularly harms human health and our environment. Regulation of outdoor VOC emissions is required to prevent the formation of ground-level ozone, which is principally responsible for photochemical smog. Indoor emissions of VOCs have been the subject of recent consideration for many governments aro...
متن کاملRemoval of Indoor Volatile Organic Compounds
Volatile organic compounds (VOCs) and formaldehyde are ubiquitous in indoor environment. 16 Inhalation of VOCs can cause irritations, difficulty breathing, and nausea, and damage the central 17 nervous system as well as other organs. Formaldehyde is even a carcinogen. Removal of VOCs and 18 formaldehyde is thus critical to control indoor air quality (IAQ). Photocatalytic oxidation has been 19 d...
متن کاملRemoval of hydrophobic Volatile Organic Compounds
23 Since usual processes involve water as absorbent, they appear not always really efficient for the treatment of 24 hydrophobic VOC. Recently, absorption and biodegradation coupling in a two-phase partitioning bioreactor (TPPB) 25 proved to be a promising technology for hydrophobic compound treatment. The choice of the organic phase, the non26 aqueous phase liquid (NAPL) is based on various pa...
