    Abstract: A system and method for providing mobile or temporary water treatment involving ion exchange resins includes a service centre, one or more treatment vehicles, a resin transfer hub and one or more resin transport vehicles. The service centre can be used to regenerate one or more types of ion exchange resins. The treatment vehicle carries water treatment equipment including a tank holding ion exchange resin. The resin transfer hub facilitates moving resin between a treatment vehicle and a resin transport vehicle. The resin transport vehicle is adapted for carrying resin by one or more of land, sea and air between the resin forwarding centre and the service centre. In operation, a treatment vehicle brings resin requiring regeneration to the resin transfer hub, where it is emptied and then re-filled with regenerated resin. Resin requiring regeneration is transferred to a resin transport vehicle for transport to the service centre. The resin transport vehicle is re-filled there with regenerated resin, which is taken back to the resin transfer hub for transferred to a treatment vehicle.

    Abstract: Electrodeionization methods and apparatus wherein ion exchange membranes are not utilized. Instead, ion exchange materials such as beads, fibers, etc., are disposed in alternating layers of anion exchange (AIX) materials and cation exchange (CIX) materials between opposite polarity electrodes. In a regeneration stage, a current is applied across the electrodes with water splitting occurring along at least one of the interfacial areas between neighboring AIX and CIX materials. The H+ and OH− ions formed via water splitting migrate in response to the electrical current and displace the salt ions in the respective AIX and CIX. The stack is flushed during the regeneration stage to remove the concentrated salt solution. During a deionization phase, the electrical current is terminated with influent fed to the stack for deionization. The salt ions in the influent are depleted via ion exchange as the influent contacts the AIX and CIX.

    Abstract: A process for providing water with a lowered salinity and which produces at least one recoverable waste stream containing a useful by-product, the process including treating raw water which includes an undesirably high concentration of cations, including Ca2+ and Na+, in a cation exchange stage which includes first and second cation exchangers. The first cation exchanger having a selectivity towards di-valent cations and the second cation exchanger being downstream of the first cation exchanger, to retain at least a portion of the cations of the raw water in or on the first and second cation exchangers, thereby providing upgraded water of a lowered salinity containing no or a low concentration of the cations of the raw water. The process further includes from time to time, regenerating the first cation exchanger with an acid to produce a first recoverable waste stream which includes a calcium salt and removing Na+ from the second cation exchanger to produce a second recoverable waste stream which includes a sodium compound, and then regenerating the second cation exchanger.

    Abstract: The invention relates to purifying unwanted moderately saline water. The methods of the present invention including passing moderately saline water through an ion exchange media saturated with ammonium salts to produce fertilizer water. In addition, the present invention relates to a method of passing moderately saline water through a dual bed cation and anion exchange process for producing purified water. The first cation exchange media is saturated with acids of hydrochloric, nitric or sulfuric acids. Meanwhile, the second ion exchange media is saturated with ammonium hydroxide. Passing the moderately saline water through the first ion exchange media creates an acid rich water which is then passed through the second ion exchange media to remove chloride, sulfate, nitrate, and nitrite anions. Through a regenerative cycle, a fertilizer water is produced which is rich in ammonium chloride, ammonium nitrate or ammonium sulfate.
