There are many chemical compounds currently in use across the globe. Different compounds have different qualities and the term volatility is often associated with the carbon based compounds called organic compounds, and a lot of organic compounds are volatile. These compounds include  hydro compounds, halo compounds, acids, alcohols, and esters. Mainly smaller compounds are volatile. However, nature also contains several inorganic molecules that are volatile. Emission of VOC in furniture and paint coating In the furniture industry, many organic compounds are utilised as solvents for polishing, painting,  in glues, etc. Besides that, solvent application is also utilised in paint and coating works and automotive paint booths in various workshops. But these solvents should be volatile. Otherwise, it will take a long time to dry. While manufacturing those products, sometimes some of the harmful volatile materials are also used to decrease production costs. This can cause suffocation along

  To estimate the odour control unit capacity of wastewater treatment facility, two factors are taken into consideration: ●        The air volume of the process tanks causes odour. ●        Air exchange factors Suppose you estimate the air volume of process tanks. In that case, you should keep in mind that in the case of a fixed water level tank, the freeboard air volume is considered, and in an unsettled water level, the air volume is considered from the lower level of water.  While designing the odour control system capacity, it is vital to consider the air exchange factors. It has a great effect on both size and effectiveness of odour elimination. Nowadays, municipalities have prepared guidance on those air exchange factors while determining the capacities of the odour control system. The air exchange factors for inlet works are deliberated in the range 12-15 of air volume, and for sludge treatment facilities, it is 6-12 air volume. It all depends on the aerated tanks, ro
