Abstract: A method and system for treating and purifying saltwater contaminated by volatile compounds. The saltwater is evaporated resulting in a gas composed of water vapor and gaseous volatile compounds. The gas is condensed into a condensate containing the contaminated volatile compounds which is biologically treated to remove the volatile compounds thereby producing purified water. The latent heat released by condensing is used to evaporate the purified water into the atmosphere in an energy efficient manner.

Abstract: Methods, systems, and techniques for desalinating a saltwater using a humidifier unit. The humidifier unit has a housing, which has a carrier gas inlet and a saltwater inlet. The humidifier unit also includes a packing, within the housing, having a surface with a critical surface tension of less than 25 mN/m according to the Zisman method. The packing is arranged to facilitate a saltwater that enters the housing through the saltwater inlet and a carrier gas that enters the housing through the carrier gas inlet to contact each other. The contact facilitates evaporation of the saltwater, which produces salt solids on at least a surface of the packing, a humidified gas and a concentrated brine.

Abstract: Systems, processes, and techniques for treating a saltwater contaminated with volatile compounds. The saltwater is evaporated, resulting in a gas composed of water vapor and gaseous volatile compounds. This gas is then condensed into a condensate contaminated with the volatile compounds. The contaminated condensate is biologically treated to remove those volatile compounds, producing a purified water. Latent heat released by the condensing is used to evaporate the purified water into the atmosphere in an energy efficient manner. The contaminated saltwater is accordingly evaporatively disposed of without creating an issue regarding how to manage substantial liquid water byproduct, and without emitting substantial amounts of the volatile compounds into the atmosphere.

Abstract: The present disclosure is directed at an apparatus, method and plant for desalinating saltwater and contaminated saltwater. The apparatus comprises a stack and a manifolding assembly. The stack comprises a product chamber, a first and second concentrate chamber, an anion exchange membrane forming a boundary between the first concentrate chamber and the product chamber and a cation exchange membrane forming a boundary between the second concentrate chamber and the product chamber. The manifolding assembly comprises product and concentrate manifolding fluidly coupled to the product and concentrate chambers respectively, to convey a saltwater being desalinated to and away from the product chamber, and a concentrate to and away from the concentrate chambers. The stack may include a diluent chamber and adjacent anion or cation exchange membranes between the product chamber, diluent chamber and concentrate chamber to respectively convey anions or cations across multiple chambers.

Abstract: A system, apparatus and method for concentrating a solution. The system includes a humidification device and a solution flow path for flow of a solution to be concentrated to the humidification device. The humidification device includes humidification media to facilitate evaporation of liquid from the solution to be concentrated to gas as the solution to be concentrated passes through the humidification media thereby concentrating the solution. The method includes flowing a solution to be concentrated along a flow path to a humidification device including humidification media, flowing a gas through the humidification media, and flowing the solution to be concentrated through the humidification media. There is evaporation of liquid from the solution to the gas as the solution passes through the humidification media thereby concentrating the solution and producing a humidified gas. The solution to be concentrated may be salt water and the gas may be air.
