| Summary: | The basic patterns and mechanisms of adsorption immobilization of sulfide-oxidizing bacteria in the mass of mineral support medium made of phosphogypsum were determined for gas purification system. The advantage of the adsorption method on the granulated support medium of phosphogypsum is that it allows to bind the bacteria in the granules with the bioactive layer formation. Granules based on phosphogypsum are characterized by permeability to Thiobacillus sp. and contain useful minerals for bacteria growth such as calcium, magnesium, phosphorus, etc. Bacterial matrix is closely associated with the support medium matrix. Therefore, its use helps minimize the removal of the sulfide-oxidizing bacteria active mass from biofilter during the process of washing and bio-sulfur removing from the surface granules of phosphogypsum. |
