What is Sulfur Reduction?

In aquaculture anaerobic sediments, water logged soils or waste streams that have become oxygen deficient because of pollution, oxidized sulfur compounds are reduced to H₂S which is a poisonous gas characterized by a smell like that of a rotten egg. This is particularly true in prawn & fish farms specially after harvest. The bacteria in NS Series Super SPO utilizes sulfur and hydrogen molecules in water, thereby tremendously reducing the production of Hydrogen sulfide (H₂S).

Although many bacteria produce sulfide from various sources in wastewater treatment situations, only a few do so at a sufficient rate for application in high-rate processes. These rapid sulfide-generating bacteria are able to conserve energy by the reduction of sulfur oxyanions like sulfate, sulfite and thiosulfate, and they are generally termed sulfate-reducing bacteria (SRB). Especially the last decade, the use of SRB for aquaculture and treatment of process and wastewaters containing sulfur compounds and metals in mining and metallurgical industries has become a topic of scientific and industrial interest. SRB were first applied on industrial scale in 1992 for the removal of sulfate and zinc from polluted groundwater at a Zink refinery in the Netherlands.
