    Abstract: A water treating apparatus is provided which can treat waste water for use as raw water in an ultrapure water producing system without addition of various kinds of chemicals. The apparatus includes a first water tank for receiving acid waste water, a second water tank for subjecting the waste water from the first water tank to solid-liquid separation and discharging supernatant liquid, an ion exchange tank including ion exchange resin and an aeration tube for generating treated water through a membrane filter, a precipitation tank for settling ion exchange resin, an air lift pump for introducing ion exchange resin from the precipitation tank into the first water tank, and a return air lift pump for returning ion exchange resin from the second water tank to the ion exchange tank. The ion exchange resin acts to exchange ions with fluorine ions of treated water in the ion exchange tank and is regenerated by acid waste water in the first water tank.

    Abstract: Disclosed is a novel continuous ion exchange apparatus capable of performing both ion exchange treatment and regeneration treatment within a single column by the use of ion exchange resin(s) whose ion exchange abilities can be regenerated by acid or alkali. The apparatus comprises a resin column or two including an adsorption zone, a washing zone, a regenerating zone sequentially sectioned from the bottom toward the top; a resin extraction transfer means for withdrawal the ion exchange resin from the bottom of the column and transferring them to a metering container disposed on the top of the column; a resin supply means for supplying the ion exchange resin within the metering container to the top of the column, a water passage system allowing the supply of feed water into the interior of the column from the bottom of the adsorption zone and allowing discharge of the treated water from the top of the adsorption zone to the exterior of the column; and a regenerant passage system allowing the supply of the regenerant from the bottom of the regeneration zone into the interior of the column and discharge of regenerant waste from the top of the regeneration zone to the exterior of the column.

    Abstract: Purification of aqueous hydrogen peroxide solutions using conventional ion-exchange techniques can result in the hydrogen peroxide decomposing explosively. Much safer processes are obtained by restricting the contact between the resin bed and the hydrogen peroxide solution to a very short contact time, by employing a treatment chamber that is vented to the atmosphere and also by slurrying the resin bed. The bed is conveniently retained on a mesh that acts as a filter (13) preferably conical having an aperture (17) at its apex through which is introduced a small fraction of the solution countercurrent (10) to the main solution flow (9) in order to slurry the bed (19). The solution can be recycled through the same bed or a plurality of beds. Very high purification can be achieved and combined with improved safety of operation.

    Abstract: Sorbable ions are removed from aqueous compositions by the use of an apparatus and method which permits the aqueous composition to flow in an uninterrupted or continuous manner. Included is a resin cycling contactor assembly which continuously accepts the flow of aqueous composition and which turbulently contacts it in a generally co-current elongated contactor path during which ions are removed from the aqueous composition and sorbed to the resin. The resin cycles within the resin cycling contactor assembly until a selected degree of resin contamination is achieved, at which time a predetermined portion of the resin is removed from the resin cycling contactor assembly and replaced by regenerated resin. The resin is regenerated within a regenerator assembly which accomplishes regeneration by counter-current flow of liquids through a packed resin bed.
