Abstract: Methods and apparatus for removing contaminants from liquid using a continuously circulating stream of purifying media are disclosed. In one embodiment the method includes mixing a regenerated purifying media with a contaminated liquid containing diverse contaminants; co-currently transporting the purifying media and the contaminated liquid in a mixed state; removing, using the purifying media, while co-currently transporting the purifying media and the contaminated liquid, contaminants from the contaminated liquid so as to produce a mixture of a decontaminated liquid and a contaminated purifying media; and separating contaminated purifying media from the decontaminated liquid. In addition, the contaminated purifying media is contacted in counter current fashion with a regenerant solution so as to produce a regenerated purifying media and the regenerated purifying media is returned to the mixing step, whereby the continuously circulating purifying media selectively removes contaminants from the liquid.

Abstract: A method for treating a fluid by providing raw fluid to a process tank, adding an ion exchange resin to the process tank to form a raw fluid/ion exchange resin mixture, removing treated fluid from the process tank through a membrane filter located within the process tank, and regenerating the ion exchange resin within the process tank. The method may be set up as a batch process or as a continuous process using a magnetic ion exchange resin and continuous withdrawal of the magnetic ion exchange resin from the process tank by use of a magnetic separator. The method may also consist of reusing the regenerant in multiple regeneration steps and periodically filtering the regenerant to restore its regenerative properties. Alternatively, an upflow bed of ion exchange resin may be used to treat the raw fluid before membrane filtration.

Abstract: The present invention relates to a method and apparatus for the continuous countercurrent desorption of targeted materials including metals, non-metals and inorganic and/or organic compounds of thereof, wherein the desorption method is divided to the two modes namely: (I) desorption and (II) re-absorption. The desorption of the target material from the loaded resin using the fresh desorbent takes place in mode (I). According to mode (I) loaded resin moves upwardly in a chamber. According to mode (II) impurities are desorbed from resin and targeted material in solution can be re-absorbed. The resin moves downwardly in another chamber during mode (II). Concentrated eluates, which are suitable for the direct economical recovery of chemical elements and/or compounds thereof, can be produced using the present invention. The apparatus of the present invention includes desorption and re-absorption zones that are configured using a “pipe-in-pipe” construction or a U-shape construction.

Abstract: A process and apparatus for continuously stripping or recovering values from a value bearing material, typically a slurry or solution thereof. The resin and value bearing material are contacted in a counter-current manner in a contact zone to load the resin with values from the value bearing material. The resin is fluidised by the value bearing material in the contact zone. The loaded resin is passed through a first washing zone to displace excess value bearing material. The loaded resin then passes through a stripping zone, typically an acid or alkali, to strip the values from the resin and form an eluate, which is treated further to recover the values. The stripped resin is washed in a second washing zone, to displace excess stripping agent, and returned to the contact zone.

Abstract: Biological nutrient removal (BNR) in municipal wastewater treatment to remove carbonaceous substrates, nutrients and phosphorus, has recently become increasingly popular worldwide due to increasingly stringent regulations. Biological fluidized bed (BFB) technology, which could be potentially used for BNR processes, can provide some advantages such as high efficiency and compact structure. This present invention incorporates the fixed-film biological fluidized bed technology with the biological nutrient removal in a liquid-solid circulating fluidized bed, which has achieved the simultaneous elimination of organic carbon, nitrogen and phosphorus, in a very efficient manner and with very compact space requirements. The BNR-LSCFB has two fluidized beds, running as anoxic/anaerobic and aerobic processes to accomplish simultaneous nitrification and denitrification and to remove carbonaceous substrates, nutrients and phosphorus, with continuous liquid and solids recirculation through the anoxic/anaerobic bed and the aerobic bed. The new BNR-LSCFB system is not only an excellent alternative for conventional activated sludge type BNR technologies but is also capable of processing much higher loadings and suitable for industrial applications.

Abstract: A continuous Liquid-Solids Circulating Fluidized Bed (LSCFB) preferably for use as an ion exchanger consists of two fluidized bed columns, a fluidized bed adsorber (downer) operating in conventional fluidized bed mode for adsorption of ions of interest and a fluidized bed riser for desorption of ions (operating as a riser fluidized bed) to provide regenerated particles. Ion exchange particles circulate continuously between the riser and the downer i.e. the particles that have adsorbed ions in the absorber pass from the adsorber (downer) to the desorber where they are regenerated and the so regenerated particles are return to the adsorber near the top of the adsorber column. The LSCFB can be used in processes for continuous recovery of the ions of interest.
