摘要:
A waste fluid is evaluated to determine if the waste fluid includes fracturing fluid requiring treatment for sodium; a hydrocarbon level requiring hydrocarbon treatment; and/or drilling fluid requiring clay treatment. The waste fluid is mixed with mature compost, organic fertilizer, and top from the well site. If the waste fluid requires treatment for sodium, calcium nitrate is mixed with the waste fluid in an amount sufficient to balance the sodium content thereof. If the waste fluid includes a hydrocarbon level requiring hydrocarbon treatment, an additional organic fertilizer is mixed with the waste fluid along with hydrocarbon-digesting microbes in an amount sufficient to inoculate the waste fluid. If the waste fluid includes drilling fluid requiring clay treatment, the waste fluid is mixed with gypsum to break up and reduce adhesive characteristics of clay particles present in the waste fluid. The mixture is stirred and dried to produce fertile top soil.

摘要:
A process for bioremediating a surface water oil spill includes mixing organic fertilizer with a floatable material selected from saw dust, wood shavings, and a combination thereof to produce a floatable bacterial nutrient, and applying the floatable bacterial nutrient onto an oil spill-impacted water surface. Hydrocarbon-digesting microbes can be added to the floatable bacterial nutrient.

Described herein are methods, apparatuses, and systems for reducing the sulfur content of coal. Coal is loaded into an apparatus comprising a vertically rotatable drum within a housing. The rotatable drum comprises a perforated cylindrical outer wall, a solid cylindrical inner wall, and a perforated, cylindrical central wall positioned between the outer wall and the inner wall, wherein the coal is loaded into a coal wash annulus between the central wall and the outer wall. A microbial wash fluid flows into a wash fluid annulus between the inner wall and the central wall, wherein the microbial wash fluid contains sulfur digesting bacteria and nutrients for the bacteria. The drum is rotated to cause the microbial wash fluid to migrate from the wash fluid annulus through the coal in the coal wash annulus and collect in a splash wash annulus between the outer wall and the housing.
