Abstract: A process is disclosed for the continuous removal of ammonia from wastewater which converts the otherwise undesirable ammonia to a commercially useful end product such as ammonium phosphate. The process is carried out in an Advanced Separation Device which comprises a plurality of chambers moving about a circular path in periodic fluid communication with a plurality of fixed feed and discharge ports. The chambers are filled with a zeolite adsorbent which effectively adsorbs the ammonium ions contained in the wastewater at low pH levels but which, when contacted with an alkaline regeneration solution, releases the previously adsorbed ammonium in the form of ammonia gas, for which the zeolite has no affinity. By virtue of the ASD design, it is possible to add acidic materials to the wastewater in an intra-stage fashion i.e. during the adsorption step so as to optimize process efficiency. Similarly, intra-stage addition of alkaline materials during the regeneration step results in increased process efficiency. The process may be practiced with both industrial and municipal wastewaters.

Abstract: Mass transfer of components from gases or liquids into porous absorbent granular media is carried out by a method using a semifluidized bed in stratified condition. The absorbent medium is composed of both small and large granules. In the stratified bed, at least part of the small size granules are captivated in a packed upper section. The larger granules are primarily in a fluidized section below the packed section. The fluid being treated flows upwardly through the bed first contacting the larger granules in the fluidized section and then exiting through the smaller packed granules. With this arrangement, increased fluid volumes can be processed before breakthrough of the component being absorbed.

Abstract: A process for the desalination of water in a continuous cyclical adsorptive operation utilizing a thermally regenerable ion retarding resin. The process employs a simulated moving bed scheme having only an adsorption zone, operated at a relatively low temperature, and desorption zone, operated at a relatively high temperature. Effluent is removed from the adsorption zone in two stages for each step of a cycle, a first stage wherein sufficient water is recovered for use as desorbent in the next step, and a second stage wherein the water product stream is withdrawn. Effluent is removed from the desorption zone also in two stages, a first stage wherein a relatively small portion having the composition of the feedstream is withdrawn, and a second stage where the extract stream having a high salt content is withdrawn.

Abstract: A method and apparatus is provided for removing large volumes of contaminants or for recovering valuable minerals present in trace amounts or greater quantities by ion exchange treatment of phosphoric acid liquids or the like as they flow through a resin bed wherein ions in the liquid are sorbed into the resin by an ion exchange mechanism. The resin bed is folded, moving bed which exhibits all of the advantages of a packed ion exchange resin bed. Laminar flows are developed at times in the moving bed system, while the moving bed used is of a "folded" type having a maximum height approximately one-third that of conventional, unfolded countercurrent units. The ion exchange treatment occurs within a loading vessel resin bed, the beads in the feed portion of which become exhausted and sequentially move out of the loading vessel for subsequent regeneration and rinsing, followed by eventual return to the loading vessel.

Abstract: A method and apparatus is provided for removing contaminants or for recovering valuable minerals in trace amounts by ion exchange treatment of liquids such as municipal and industrial waste waters, ore mining and processing tailings, and the like as they flow through a resin bed wherein ions in the liquid are sorbed into the resin by an ion exchange mechanism. The resin bed is a folded, moving bed which exhibits all of the advantages of a packed ion exchange resin bed. Laminar flows are developed throughout the moving bed system to maintain all interfaces intact, even during the rinsing operation, while the moving bed used is of a "folded" type having a maximum height approximately one-third that of conventional countercurrent units. The ion exchange treatment occurs within a loading vessel resin bed, the beads in the feed portion of which become exhausted and sequentially move out of the loading vessel for subsequent regeneration and rinsing, followed by eventual return to the loading vessel.

Abstract: An ion exchange process for desalination wherein a thermally regenerable ion exchange resin having weakly acidic free acid groups and weakly basic free base groups is carbonated, for example by contact with an H.sub.2 CO.sub.3 solution, whereby the free base groups are converted to a carbonate form. The conversion may be effected either prior to or simultaneously with contact between the resin and the solution to be desalinated. Both fixed bed and continuous or semi-continuous resin systems are usable. The process maintains the desalination capacity at a high level while providing effective desalination.
