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:
Disclosed are water treatment systems and methods that are characterized by reduced leaching of color-bearing material (i.e., color-bearing leachates) into effluent water. The disclosed systems and methods may include or utilize filtering systems comprising selected mixed ion-exchange resin beds of a strong acid sulfonated cation exchange resin and an anion exchange resin.
Abstract:
A processing method of liquid includes: decomposing a resin in liquid by allowing ozone gas to contact the liquid containing a water-soluble carbonyl compound and the resin; and removing organic acid generated by decomposing the resin in the decomposing step from the liquid by performing on the liquid after being subjected to the decomposing step an ion exchange process using an ion exchange resin. The liquid to be subjected to the ion exchange process contains water.
Abstract:
An adsorptive filter material for the adsorption of acids or acid forming substances from the air is presented, which comprises an ion exchange material. The ion exchange material comprises a strong alkaline anion exchange resin with a ratio of at least 60% in the hydrogencarbonate form and a cation exchange resin in the H form with a ratio of not more than 15%.
Abstract:
The present invention relates to a non-agglomerating, readily separable mixed bed ion exchange system comprising: (a) a strong base quaternary ammonium anion exchange resin wherein said anion exchange resin has been pretreated with 10 to 800 milligrams of water-soluble sulfonated poly(vinylaromatic)polyelectrolyte per liter of anion exchange resin; wherein the number average molecular weight of the sulfonated poly(vinylaromatic)polyelectrolyte is from 5,000 to 1,000,000; and (b) a strong acid sulfonated cation exchange resin wherein said cation exchange resin has been pretreated with 10 to 800 milligrams of a water soluble cationic polyelectrolyte selected from the group of polymers consisting of poly(vinylaromatic)quaternary amine salts, poly(vinylaromatic)tertiary amine acid salts, or poly(vinylpyridines) acid salts, wherein the number average molecular weight of said polymers is from 5,000 to 1,000,000.
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.
Abstract:
A novel deionization filter for removing ions from a coolant in an electric fuel cell vehicle cooling system is disclosed. The deionization filter includes a filter housing having a coolant inlet port, through which the coolant enters the filter housing; and a coolant outlet port, through which the coolant exits the filter housing. An ion exchange bed having positively-charged and negatively-charged ion exchange resin beads is provided in the filter housing for removing negative and positive ions, respectively, from the coolant. At least one filter assembly is typically provided in the filter housing for filtering particles from the coolant.
