The physico-chemical methods are highly efficient and suitable for removal of objectionable odours of gases, such as H2S, NH3, (CH3)2S or VOC (volatile organic compounds).
Works conducted in wastewater treatment plants and in many industrial buildings and facilities bring about a risk of problems connected with objectionable odours. In past, cumbersome odours from biological processes were liquidated by the use of biological filters. How-ever, operations of such bulky filters are not reliable and they are expensive. At present, there are in place reliable physico-chemical processes using ionisation or photocatalytic re-actions for treatment of tail gases.
