Abstract: A coal treatment system, comprising an advanced coal treatment stage configured to produce ultra clean coal, wherein the stage comprises a leaching agent treatment system configured to remove a mineral from the coal and form a wastewater stream; and a dewatering system in fluid communication with the leaching agent treatment system and configured to reduce a concentration of a contaminant in the wastewater stream, wherein the dewatering system comprises a reverse osmosis membrane in fluid communication with the wastewater stream.

Abstract: A process for treating coal includes contacting the coal with a leaching agent configured to remove a mineral from the coal; forming a wastewater stream comprising water and a concentration of a contaminant; and contacting the wastewater stream with a first side of a reverse osmosis membrane under pressure, wherein a permeate stream comprising a reduced concentration of the contaminant permeates the reverse osmosis membrane and flows from a second side of the reverse osmosis membrane, and a concentrate stream comprising an increased concentration of the contaminant is retained on the first side of the reverse osmosis membrane.

Abstract: A method for remediating bacterially-induced corrosion, environmental damage, and/or process inefficiencies in an industrial process includes identifying an industrial process where target bacteria adversely affect corrosion, environmental impact, and/or process efficiencies. The process also includes identifying the strains of the target bacteria, obtaining a bacteriophage virulent against one or more of the strains of the target bacteria, and exposing the target bacteria to the bacteriophage. The method can utilize an aqueous composition comprising bacteriophage encapsulated in at least one selected from the group consisting of: liposomes, foam, and gel.
