Abstract
A continuous process for the microbiological conversion and removal of malodorous sulphur-containing organic and inorganic compounds from a gaseous stream, comprising the steps of providing a column filled with packing material. Passing a biologically active liquid stream containing nutrients and a consortia of bacteria including microorganisms of the Thiobacillaceae family through the column whereby the bacteria are immobilized onto all available surface area of the packing material. Maintaining the temperature conditions within the column between about 5.degree. C. to about 47.degree. C. and the pH conditions between about 5 to about 9. Concurrently passing a gaseous stream containing the malodorous sulphur-containing organic and inorganic compounds through the column at a liquid gas ratio of about 3:7 for a sufficient period of time to allow the bacteria to convert greater than about 97% of the sulphur compounds within the gaseous stream into a useful form of elemental sulphur.
