    4. Physico-chemical efficacy and olfactometric performance on single compounds

    4.1 Non-exhaustive list of commercial products tested

    Table 4 lists products marketed as odor masking or neutralizing agents. The recommended dilutions of these products in water vary from 0.1% to 5% on average; nevertheless, the flow rates of liquid sprayed or misted are high, so consumption is substantial and operating costs relatively high. In addition, some suppliers recommend an optimum droplet diameter for good performance. This generally corresponds to drops obtained by misting or atomizing the liquid (of the order of ten micrometers). Finally, while some products target specific odor compounds, others are marketed as multi-purpose odor eliminators (e.g. household waste odors, or odors from landfill sites), and it is...
