    Abstract: A process for removing suspended particles and at least one ionic species from a feed water stream to produce a product water stream, the process includes the steps of forming agglomerates of the suspended particles in the feed water stream; passing the feed water stream containing agglomerated particles through a bed of particulate sorbent material so as to sorb the ionic species from the feed water onto the sorbent to provide a loaded sorbent and filter the agglomerated particles from the feed water using the bed of particulate sorbent material as a filtration medium to load the bed with the agglomerated particles, and thereby produce the product water stream; removing the filtered particles and the ionic species from the filtration medium; and re-using the regenerated sorbent in step b).

    Abstract: The invention provides waste water treatment processes utilizing an ion exchange resin to remove sulphate anions, while adjusting the pH of the ion exchange loading solution with carbon dioxide gas. The effect of the resin loading reactions is that dissolved sulphate is replaced with sequestered carbon dioxide gas, in the form of dissolved bicarbonate, in the treated water and the cations are not removed from the solution.

    Abstract: A method for recovering and/or utilizing potassium from waste waters for a plurality of applications. As algae and plants are able to survive and flourish in environments with high salt concentrations, waste waters containing potassium can be applied as fertilizers to the growth of microbes, algae and plants. The microbes, plants, and algae are able to absorb the necessary nutrients, such as nitrogen and potassium, from the waste waters. After depletion of the potassium content from the waste water, that waste water can then be treated to separate other contaminants. In another aspect of the present invention, the potassium content may be first separated from the waste water to be applied for growth of microbes, plants, and algae and again used for regeneration of cation resins in specific potassium forms. The remaining contaminants that are separated through treatment of the waste water can be utilized for different productions.

    Abstract: According to the process for producing amino acid or salt thereof in the present invention, in the adsorption step, an amino acid-containing aqueous solution is fed into a pressure tight column so that a free amino acid is adsorbed on a carbonate-type anion exchange resin packed in the pressure tight column. Subsequently, in the elution step, eluent liquid containing a hydrogen carbonate ion and/or a carbonate ion is injected into the pressure tight column in a pressurized state to elute the amino acid adsorbed on the anion exchange resin and simultaneously to regenarate the anion exchange resin into the carbonate-type. In the case of purifying an acidic amino acid, an aqueous ammonium carbonate solution is employed as the eluent liquid. In the case of purifying a neutral amino acid, an aqueous carbonic acid solution, an aqueous hydrogen carbonate solution, an aqueous ammonium hydrogen carbonate solution or an aqueous ammonium carbonate solution is employed as the eluent liquid. Further, a breakthrough liquid discharged from the adsorption step is optionally concentrated to remove the volatile carbonate acid component and ammonium component from the breakthrough liquid. Thus, the solid content in the breakthrough liquid can be reduced.
