Abstract

   The generation of odours in a WWTP is usually caused by the presence of hydrogen sulphide (H2S). This gas, moreover, is responsible for the deterioration of the facilities’ materials and involves a health hazard for plant operators. Currently there are several alternatives that allow decreasing the impact of odours associated with H2S. This paper presents some techniques focused on management of odours in WWTPs as a result of the experience of DAM as WWTP Manager.

   Experiences include the removal of hydrogen sulphide (H2S) in collectors or the deodorization of a WWTP by the injection of confined air in the anoxic biological reactor of the sludge line. Studies at pilot scale for the application of a TECNIUM’s biofilter percolator or the photo-ionization for the treatment of air streams, and ozone plus ultrasound for the treatment of liquid streams have been also included.
