Methods are disclosed for reducing oil in water emulsions in coking processes. One exemplary method comprises: providing an aqueous stream with an oil in water emulsion; providing a treatment composition, wherein the treatment composition comprises at least one cationic polyacrylamide; and contacting the aqueous stream with the treatment composition.

A multistage desalination process for treatment of seawater or salt wastewater. During initially processing the seawater or salt wastewater is treated to precipitate scaling minerals as phosphates including magnesium ammonium phosphate useful as a fertilizer. During the initial phase, ammonium phosphate and sodium phosphate are added to the seawater or salt wastewater followed by an addition of ammonia and a water-based charged solvent. After separating the precipitated solids, the cleaned seawater or salt wastewater is aerated and filtered to produce potable or otherwise usable water.

An article of manufacture for providing a water salinizer to add salt to pool water is disclosed. The water salinizer includes a barrel having a sidewall, a convex bottom, an angled sidewall between the convex bottom and the side wall, and an opening is a top surface for dissolving material into water, an input port coupled to the angled sidewall and being configured with the convex bottom to direct an incoming pressurized water stream and salt around the barrel along the angled sidewall, and a discharge port coupled to the sidewall about the opening in the top surface on an opposite side of the barrel from the input port.

The present invention describes a powder mixture and delivery method for the treatment of wastewater and water streams for the removal of phosphorus-containing compounds. The solid mixture is comprised of an aluminum-based coagulant mixed with a magnesium-containing compound and, optionally, additional compounds to aid in the control of pH, alkalinity, sludge production, settling rate, and other factors. This solid mixture is delivered to a wastewater stream or unit process where the aluminum-based coagulant works to react with, flocculate, and/or coagulate phosphorus compounds prior to their removal.

A mineral composition for generating small water clusters, a small water cluster generating device and a seawater desalination equipment using the same and a small water cluster generating method are provided. The mineral composition includes a tourmaline, a quartz, a bleaching earth, a dolomite, a shale, and a porcelain clay. The small water cluster generating device includes the mineral composition and an energy supplying unit for supplying energy. The seawater desalination equipment includes the mineral composition, a heat supplying unit, and a cooling unit. The small water cluster generating method includes using the mineral composition on water or a solution and providing the energy.

A method of making a facile, surface-independent, polyphenol coating is disclosed. In general, the method includes contacting at least a portion of the substrate to be coated with an aqueous solution containing one or more salts and one or more nitrogen-free phenolic compounds. Substrates of all kinds may be used, and compounds used to make the coating may include epigallocatechin-3-gallate (EGCG), epigallocatechin (EGC) and epicatechin-3-gallate (ECG), tannic acid, gallic acid, pyrogallol, and/or other nitrogen-free phenolic compounds. The coating made using the method, methods of using the coating, and kits comprising the coating precursors are also disclosed.

The present invention relates to a Myoviridae bacteriophage Esc-COP-1 that is isolated from the nature and can kill specifically Shigatoxin-producing type F18 E. coli strains, which has a genome represented by the nucleotide sequence of SEQ. ID. NO: 1 (Accession NO: KCTC 12662BP), and a method for preventing and treating the infections of Shigatoxin-producing type F18 E. coli using the composition comprising said bacteriophage as an active ingredient.

The present invention relates to a Myoviridae bacteriophage Esc-COP-4 that is isolated from the nature and can kill specifically enteroinvasive E. coli strains, which has a genome represented by the nucleotide sequence of SEQ. ID. NO: 1 (Accession NO: KCTC 12663BP), and a method for preventing and treating the infections of enteroinvasive E. coli using the composition comprising said bacteriophage as an active ingredient.

Selective scaling in water treatment systems in which desalination is performed is generally described. According to certain embodiments, the location of the formation of solid scale within a water treatment system is controlled by adjusting one or more system parameters, such as the temperature and/or flow velocity of a saline stream within the water treatment system.

A desalinating system and method is disclosed. The desalination system comprises using a turbo freeze or fast-cooling process to freeze saline water droplets and separate salt crystals from pure water crystals, wherein said system provides for simultaneous injection of saline water droplets and a chilled refrigerant into a freezing chamber at a slip velocity sufficient to reduce the size of the saline water droplets to an optimal diameter.
