    Abstract: A treatment system for removing metal ions from water and a method for cleaning the system. Contaminated water is passed through a plurality of columns having ion-extracting agents therein. When saturated with ions, each column is successively cleaned with primary and secondary acid solutions from separate vessels. When the primary acid is saturated with ions, it is membrane-filtered to remove ions therefrom. The secondary acid is then directed into the primary acid vessel, with the purified primary acid being routed back into the system (preferably into the second vessel) for reuse. The column is then rinsed with water, washed with an alkali solution (periodically concentrated using a water-permeable membrane), and rinsed again with water. The system preferably uses three columns, all of which are successively cleaned in the manner described above.

    Abstract: A back rinse arrangement for ion exchange resin in an ion exchange bed through which a liquid to be treated flows in a substantially vertical direction to have contaminants captured therefrom in the ion exchange resin includes an inlet chamber arranged at a lower region of the fixed bed, an injector that opens into the inlet chamber and has a transporting and rinsing liquid selectively supplied thereto, and a conveying and cleansing pipe which extends vertically through the fixed bed and provided with an outlet opening at its upper end. The particulate ion exchange resin, which is particulate or granular, is gradually withdrawn by the flowing transporting and rinsing liquid from the lower region of the fixed bed, and is conveyed through the conveying and cleansing pipe, with simultaneous performance of a cleansing action, to the upper region of the fixed body which gradually descends as the ion exchange material is being withdrawn from its bottom region. The transporting and rinsing liquid which has been contaminated by the contaminants released from the ion exchange resin during its regeneration is removed from the fixed bed.

    Abstract: A separation device designed to effect substantially continuous separation and/or fractionation operations as in, for example, ion exchange or other solid-fluid contacting systems. Also disclosed and claimed is a method for effecting such continuous treatment of plural fluid streams. The device is characterized by its construction to permit treatment of plural streams simultaneously and continuously. Fixed inlet and outlet nipples are provided for introducing and removing the fluid streams, and the inlet and outlet nipples are operatively interconnected by a rotating member which is internally divided into a plurality of working sections. By virtue of the rotatable construction of that member and its plural working sections, discrete fluid streams may be treated separately, yet simultaneously. Furthermore, the device of this invention is such that fluid flow in either of two directions may take place through each of the working sections dependent only upon predetermined process parameters.

    Abstract: A relatively compact and inexpensive technique for the two step decontamination of a liquid such as water is described. The liquid to be treated is propelled upwardly through a pair of vertically superposed, lower and upper chambers defined in a common treatment tank and separated by a liquid-permeable nozzle member. A first decontamination-removing substance, such as adsorbing material or an ion exchanger, is disposed in the lower chamber, while a second decontamination-removing substance such as activated charcoal is disposed in the upper chamber. The first substance, when spent, is propelled out of the lower chamber by a transport liquid, externally renewed, and recirculated back into the second chamber as a fresh charge by passing through a central pipe that extends through the upper chamber and the nozzle member to terminate in the lower chamber. The second substance, when spent, is renewed either by means of direct rinsing with the transport liquid flowing downwardly into the lower chamber as discussed above, or is first propelled out of the tank by means of such transport liquid and is then externally rinsed and then recirculated to the upper chamber. The fully-treated liquid exits from the top of the common treatment tank.

    Abstract: In a fixed-bed ion exchange process for treating a fluid, wherein adsorption and regeneration are performed in countercurrent flow, the whole ion exchange resins are removed from the ion exchange column portionwise, either intermittently or continuously, subjected to backwash and then returned to the ion exchange column. The whole bed of the resins is replaced by one round in this process, and therefore the distribution of the ions in the resin bed after backwash treatment is substantially the same as before, whereby a very efficient ion exchange is possible without increase in amount of the regenerant.

    Abstract: In a fixed-bed solid-fluid contacting process, wherein adsorption and regeneration are performed in countercurrent flow, a portion of contaminated solid particles in the bed is extracted from the bed for washing, simultaneously when a fluid is treated by passing through the bed. The solid particles extracted are washed and recycled to the bed at the time of other operations, for example, regeneration step. The process is improved in the time cycle of treatment which is shortened and the pressure loss which is decreased. The process is also free from disturbance of bed and excellent in treatment efficiency. A simple and compact apparatus is available for the process. Typical example of application is ion exchange reaction.
