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: Methods, systems, and techniques for removing ammonium from ammonia-containing water involve using a stack that has alternating product chambers and concentrate chambers for receiving ammonia-containing water and an acidic solution, respectively, with the chambers being bounded by alternating cation exchange membranes and proton permselective cation exchange membranes. Ammonium moves from the product chambers to the concentrate chambers across the CEMs and protons move from the concentrate chambers to the product chambers across the pCEMs when the stack is in use. An electrolyzer may also be used to convert the ammonium in the concentrate chambers into nitrogen.
