The invention is a high-salt waste water air powered low temperature evaporating device and method of use. A tray is mounted on a lifting platform; an air inlet and a water inlet are on the tray. Air distributing pipes are arranged at the center of the nested column tubes (33). A groove (4) is installed at the top of the tray, and mounting points are accompanied by multiple nested column tubes (33). The nested column tubes (33) are connected with the air inlet. An atomizer is arranged inside the air distributing pipes; and the atomizer is connected with the water distributing pipes. Using air power evaporates concentrated waste water multiple times so that the salt in the wastewater reaches saturated concentration, and therefore, the wastewater temperature is reduced, salt is crystallized and separated out, liquid is continuously evaporated, and the wastewater can be completely treated.

Described herein is a method for purging paint circuits coated with a non-cured paint with improved cleaning efficiency and a reduced COD (Chemical Oxygen Demand) in the wastewater, where a paint circuit is brought into contact with a waterborne purge cleaner solution including at least one glycolether and which additionally includes at least one water-soluble amine having at least 7 carbon atoms. Also described herein is a waterborne purge cleaner solution with improved cleaning efficiency and reduced VOC (Volatile Organic Compound) content as well as a concentrate for producing the purge cleaner solution.

Provided is a microbicide-containing aqueous composition having a superior effect of stabilizing 5-chloro-2-methyl-4-isothiazolin-3-one. This microbicide composition includes: (A) 5-chloro-2-methyl-4-isothiazolin-3-one; (B) 2,2,6,6-tetramethylpiperidin-1-oxyl; and (C) at least one solvent selected from the group consisting of water and a hydrophilic organic solvent.

A method for purifying dye-containing wastewater based on a porous-polymer-modified metal carbon nanotube membrane includes: (1) preparing the porous-polymer-modified metal carbon nanotube membrane; and (2) passing the dye-containing wastewater through the porous-polymer-modified metal carbon nanotube membrane to remove dyes in the dye-containing wastewater. A device for purifying dye-containing wastewater is also disclosed. The device includes the porous-polymer-based metal carbon nanotube membrane.

In an embodiment, a circuit includes: a transformer defining an inductive footprint within a first layer; a grounded shield bounded by the inductive footprint within a second layer separate from the first layer; and a circuit component bounded by the inductive footprint within a third layer separate from the second layer, wherein: the circuit component is coupled with the transformer through the second layer, and the third layer is separated from the first layer by the second layer.

Described is a system and corresponding method for remediating liquid waste streams. The system includes an electro-oxidation (EO) chamber, an electro-deposition (ED) chamber, and an electro-adsorption (EA) chamber. In the method, a waste stream is subjected to electro-oxidation, followed by electro-deposition and/or electro-adsorption. The method removes both organic and inorganic pollutants, as well as metals present as free ions or bound into organic or inorganic complexes.

The present invention provides a method for treating water containing pollutants, comprising the steps of 1) bringing said water in contact with magnetoelectric particles so that the pollutants in the water come into contact with the surfaces of magnetoelectric particles; 2) applying a magnetic field to the magnetoelectric particles so as to generate electric charges on the surface of said magnetoelectric particles, wherein said electric charges on the surface of said magnetoelectric particles cause redox reactions to occur which oxidize said pollutants in the water. Also provided arm water cleaning reactors which can be used to perform the method of the present invention and water cleaning assemblies which use any of said water cleaning reactors.

Disclosed herein are methods and compositions useful in recycling automotive paint sludge in the formation of ore pellets. In many embodiments, the pellets are iron ore pellets comprising magnetite ore, and one or more of limestone and bentonite. The automotive paint sludge may be water based or other solvent based. In many embodiments, the disclosed methods and compositions may result in pelletized ore with performance characteristics (hardness, resistance to breakage, porosity, reduction, etc.) that are similar or superior to pelletized ore lacking paint sludge.

In an embodiment, a circuit includes: a transformer defining an inductive footprint within a first layer; a grounded shield bounded by the inductive footprint within a second layer separate from the first layer; and a circuit component bounded by the inductive footprint within a third layer separate from the second layer, wherein: the circuit component is coupled with the transformer through the second layer, and the third layer is separated from the first layer by the second layer.
