What is the sulfur cycle in wastewater?
The Sulfur Cycle in Wastewater Systems 1 Sulfate Reducing Bacteria - these bacteria under anoxic conditions use sulfate as electron acceptor to degrade organics. If you have oxygen or nitrate in the system, sulfate reducing bacteria are outcompeted by harmless bacteria that obtain more energy using oxygen or nitrate as an electron acceptor. 2 Sulfur Reducing Bacteria - these chemotrophic bacteria obtain energy by reducing sulfur into sulfide. In most wastewater, these are less common than the Sulfate Reducing Bacteria that use sulfur as an alternative electron acceptor. You would find these organisms in mines, subsea volcanic vents, hot springs, and oil formations. 3 Sulfur Oxidizing Bacteria - chemotrophic bacteria with the metabolic ability to convert reduced sulfur species into sulfur and sulfate. While some species can use nitrate as the electron acceptor, most sulfur oxidizers require oxyen as the terminal electron acceptor. If taken to conclusion, you produce sulfuric acid (H2SO4). These are the well documented sewer corrosion bacteria that can form if a vapor phase H2S concentration reaches sufficient levels. In wastewater, Sulfur Oxidizing Bacteria (SOB) are vital to removing reduce sulfides. This does require alkalinity to buffer the system from pH drop. Common genera of wastewater SOB include Thiobacillus, Anwoodia, Paracoccus, and Thiosphaera.

World production in the year 2004 was about 180 million tonnes, with the following geographic distribution: Asia 35%, North America (including Mexico) 24%, Africa 11%, Western Europe 10%, Eastern Europe and Russia 10%, Australia and Ocea…
Physical properties
Although nearly 100% sulfuric acid solutions can be made, the subsequent loss of SO3 at the boiling point brings the concentration to 98.3% acid. The 98.3% grade is more stable in storage, and is the usual form of what is described as "concentrated sulfuric acid". Other concentrations are used for different purposes. Some common concentrations are:
"Chamber acid" and "tower acid" were the two concentrations of sulfuric acid produced by the lea…
Chemical properties
Because the hydration reaction of sulfuric acid is highly exothermic, dilution should always be performed by adding the acid to the water rather than the water to the acid. Because the reaction is in an equilibrium that favors the rapid protonation of water, addition of acid to the water ensures that the acid is the limiting reagent. This reaction is best thought of as the formation of hydronium
Occurrence
Pure sulfuric acid is not encountered naturally on Earth in anhydrous form, due to its great affinity for water. Dilute sulfuric acid is a constituent of acid rain, which is formed by atmospheric oxidation of sulfur dioxide in the presence of water – i.e. oxidation of sulfurous acid. When sulfur-containing fuels such as coal or oil are burned, sulfur dioxide is the main byproduct (besides the chief p…
Manufacture
Sulfuric acid is produced from sulfur, oxygen and water via the conventional contact process (DCDA) or the wet sulfuric acid process (WSA).
In the first step, sulfur is burned to produce sulfur dioxide.
S(s) + O2 → SO2
The sulfur dioxide is oxidized to sulfur trioxide by oxygen in the presence of a vanadium(V) oxide
History
The study of vitriol, a category of glassy minerals from which the acid can be derived, began in ancient times. Sumerians had a list of types of vitriol that they classified according to the substances' color.
