Deep social awareness, especially in highly developed countries, imposes pressure on entrepreneurs and service providers, forcing them to undertake effective actions to minimize the effects of their activities also in terms of the emission of malodorous substances. The article presents information on the absorption processes harnessed in the deodorization of gases from wastewater management and the characteristics of these gases. Avoiding emissions is not always possible, hence there is a need to conduct an inventory of such gases and use deodorization methods. The specificity of gases from wastewater management and their prevalence urge the search for cheap and easy-to-use deodorization methods. It is obvious that the selection of deodorization technology is driven by many factors and should be preceded by a thorough analysis of the possibilities and limitations of various solutions. The aim of this article is, therefore, to present the characteristics of gases from wastewater management and to discuss various technologies based on absorption processes as a technology for deodorizing such gases in order to help potential investors choose an emission-reducing method suitable for particular conditions.•Malodorous substances in wastewater management.•Deodorization using water and chemical absorption.•Deodorization using biological purification.
Keywords: Deodorization; Deodorization technology; Malodorous gases emission limitation; Malodorous substances removal; Scrubber; Sewage treatment.
