Work in WWTP’s and in a number of industrial halls and production plants represents a potential hazard, in the occurrence of problems having to do with foul odours. In the past, annoying odours from biological processes were eliminated with the use of biological filters. However, these filters did not manifest high operational reliability, were voluminous, and required considerable operating costs. Today, reliable physical-chemical technologies are available that use the ionization of photocatalytic oxidation in the treatment of these waste gases.
FThe physical-chemical methods are very effective and suitable for eliminating unpleasant odours, such as H2S, NH3, (CH3)2S and VOC.
