摘要： A method for improving indoor air quality in a room, comprising drawing air from the room and guiding the air into a gas/liquid contactor charged with aqueous alkali hydroxide/H2O2 solution, passing the air through a perforated membrane installed in the gas/liquid contactor below the surface level of the aqueous alkali hydroxide/H2O2 solution, such that bubbles produced travel through said solution, and getting treated air with improved quality from said gas/liquid contactor, said treated air is characterized by having: reduced carbon dioxide levels; and/or reduced VOC levels; and/or reduced microbiological load. An air purifier to carry out the method is also provided.

摘要： This disclosure relates to improved methods for alkali metal cyanide production, particularly to improved methods for sodium cyanide production. The improved method of producing sodium cyanide involves the step of contacting hydrogen cyanide with an aqueous solution of sodium carbonate or of a mixture of sodium carbonate and sodium bicarbonate to produce a sodium cyanide solution.

摘要： Aspects of the invention include methods of removing carbon dioxide (CO2) from a CO2 containing gas. In some instances, the methods include contacting CO2 containing gas with a bicarbonate buffered aqueous medium under conditions sufficient to produce a bicarbonate rich product. Where desired, the resultant bicarbonate rich product or a component thereof may then be stored or further processed, e.g., combined with a divalent alkaline earth metal cation, under conditions sufficient to produce a solid carbonate composition. Aspects of the invention further include systems for practicing the methods, as well as products produced by the methods.

摘要： A membrane module includes a housing. The housing includes a housing, comprising: a first plurality of porous hollow fiber membranes, and a second plurality of porous hollow fiber membranes different from the first plurality of porous hollow fiber membranes. The first plurality of porous hollow fiber membranes has a first length, and the second plurality of porous hollow fiber membranes has a second length that is at least 1.1 times greater than the first length. The membrane module can be used in separation methods, such as membrane distillation methods.

摘要： An apparatus and methods to eliminate PFAS from wastewater biosolids through fluidized bed gasification. The gasifier decomposes the PFAS in the biosolids at temperatures of 900-1800° F. Synthesis gas (syngas) exits the gasifier which is coupled to a thermal oxidizer and is combusted at temperatures of 1600-2600° F. This decomposes PFAS in the syngas and creates flue gas. Heat can be recovered from the flue gas by cooling the flue gas to temperatures of 400-1200° F. in a heat exchanger that is coupled with the thermal oxidizer. Cooled flue gas is mixed with hydrated lime, enhancing PFAS decomposition, with the spent lime filtered from the cooled flue gas using a filter system that may incorporate catalyst impregnated filter elements. The apparatus and methods thereby eliminate PFAS from wastewater biosolids and control emissions in the resulting flue gas.
