A method of producing sulfurous acid can include: providing sulfur to the primary burn chamber; burning a first portion of the sulfur in the primary burn chamber to form a first portion of sulfur dioxide; burning a second portion of the sulfur in the secondary burn chamber to form a second portion of sulfur dioxide; and mixing the first portion and second portion of sulfur dioxide with an aqueous composition so as to produce aqueous sulfurous acid.

Abstract: A method of generating organic fertilizer material may include generating biologically produced sulfuric acid by passing an aqueous solution including sulfur over a material that may include sulfur oxidizing microorganisms. The operations may further include, recirculating the aqueous solution over the material until an amount of biologically produced sulfuric acid in the aqueous solution may reach a predefined threshold. The operations may further include extracting the biologically produced sulfuric acid from the aqueous solution. Further, the operations may include generating the organic fertilizer material using the extracted biologically produced sulfuric acid and an organic feedstock.

Abstract: A method of controlling aquatic pests: introducing sulfurous acid into water having the aquatic pests to treat the water until the aquatic pests are controlled, wherein the water is selected from open water, flowing water, or water open to the atmosphere. The aquatic pests are controlled within a control distance, which is within a distance of less than a mile from the site of introducing the sulfurous acid. The water can be open water or contained water, and the method comprises producing the sulfurous acid at a site of sulfurous acid introduction into the water. The aquatic pest is a zebra mussel, an Asiatic clam, a bryozoan or others. The method can include introducing the sulfurous acid so that the treated water has a pH of between about 6 and 6.5. The method can include introducing the sulfurous acid so that the treated water includes sulfites, bisulfites, and/or sulfur dioxide.
