Abstract: An ion-exchange water purification method and system. Feed water is exposed in countercurrent to active media in a vessel, resulting in treated water and spent media. The treated water flows upwards in the vessel and is recovered. The spent media flows to a regeneration zone of the vessel below the active media and is exposed to a regenerant in the regeneration zone, resulting in regenerated media and spent regenerant. The regenerated media flows to a point above the active media and from the point above the active media toward the active media while treated water flows upwards in countercurrent from the active media toward the regenerated media, rinsing the regenerated media and resulting in rinsed media and rinse water. The rinsed media flows to the active media and is combined with the active media.

Abstract: A method for deep removal of divalent and trivalent scaling ions from heavy oil produced water is described. The method comprises performing divalent and trivalent scaling ion deep removal treatment on heavy oil produced water by using a macroporous weak acid resin, to reduce divalent and trivalent scaling ions in the heavy oil produced water to 50 μg/L. The water quality of produced water treated using the method is superior to the boiler water standard, a silicon removal process in a conventional heavy oil produced water treatment process can be cancelled, and significant economic benefits are achieved.

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: In a sewage treatment plant, dissolved ammonium is extracted from the waste-water stream, and is transferred to a body of secondary water. The secondary water is passed through an electrolysis station, where the ammonium is transformed to nitrogen gas. The capture and transfer can be done by ion-exchange, the electrolysis then being done on the regenerant water. Or the capture and transfer can be done by first transforming the dissolved ammonium to ammonia gas by raising the pH of the waste-water, then passing the ammonia gas through acidic secondary-water, in which the ammonia dissolves, the electrolysis then being done on the acid-water. The electrolysed, ammonium-diminished, secondary-water can be re-used in further capture/transfer episodes. The secondary-water does not mix with the waste-water stream.

Abstract: A system and method configured to restore ion exchange kinetic properties and purify resin is described. Degraded ion exchange kinetic properties of anion resin will eventually result in impurity slippage through resin charges. This system and method employs an acid catalyst in combination with sulfite cleaning solution to remove organic material and to protonate iron oxides for deconstruction and removal from anion resins. The cleaning solution, when applied via a cleaning vessel utilizing an eductor(s)/plenum and wedge-wire screen draw chamber, while controlling all phases of cleaning by electronic monitoring, yields complete restoration of ion exchange kinetics on usable resin. As such, the system and method provides a safe, effective, and vastly improved method for restoring anion resin kinetics and improving regeneration quality, for improved resin performance and minimizing resin replacement costs.

Abstract: A process for the recovery of a radioisotope from a waste resin of a nuclear power plant comprises the steps of: a) treating a waste resin loaded with at least one radioisotope with an organic acid or alkaline compound to release the at least one radioisotope and to obtain a process solution containing the at least one radioisotope; b) separating the at least one radioisotope from the process solution through a reaction specific to the radioisotope so as to obtain a treated process solution depleted of the at least one radioisotope, wherein said depleted process solution comprises the organic acid or alkaline compound and optionally a non-reacted radioisotope; c) reacting the organic acid or alkaline compound in the depleted process solution from step b) by thermal and/or photochemical oxidation to form gaseous reaction products; and d) reloading the waste resin with the reacted process solution from step c) to bind the non-reacted radioisotope on the waste resin. Further, an apparatus is provided to carry out the above method.
