Purpose of the development: Sewage treatment plants metalworking, surface water and acid mine drainage.

Recommended application field: Wastewater treatment plant.

Advantages over analogues: The new technology is based on the natural ability of sulfate-reducing bacteria (extracellular deposition mechanism) to recover metal sulfates to nearly insoluble sulfides easily removed.

The development stage readiness: tested in laboratory condition

Technical and economic effect: CRP could produce large amounts of hydrogen sulfide, which reacts readily with cations of heavy metals dissolved in the aqueous solution to form soluble sulfides. Bacteriological recovery of sulfates can be used in the treatment of wastewater generated in the production of metal, surface water and acid mine drainage, which is quite a serious problem during mining operations.

Description of the development:
()
The technology developed by the Slovak Research Institute, based on the natural ability of sulfate-reducing bacteria (extracellular deposition mechanism) to restore the metal sulfates to practically insoluble sulfides easily removed. Elemental sulfur - another product of the recovery process. Heavy metals - environmental contaminants, mainly of anthropogenic origin. Their main source - industrial waste water. Sulfate-reducing bacteria (SRB) - the microorganisms to be used for biotechnological processes, are a group of hemoorganotrofnyh, anaerobic gram-negative bacteria, the large morphological and physiological diversity. Despite the considerable morphological diversity, they all share in the anaerobic respiration sulfates as electron acceptors and reduced them to sulfides. Electron donors in these processes - simple organic compounds or hydrogen.
