The present invention provides novel methods for removal and disposal of ammonia from spent dialysate in a dialysis system. Ammonium ions present in spent dialysate are converted into gaseous ammonia by raising the pH of the spent dialysate solution in a first reactor.

The second reactor converts gaseous ammonia into an ammonium compound for easy disposal.

Fresh or stockpiled cement kiln dust is moistened with sufficient water so that the amount of total free and combined water relative to dust is about 3 parts water to 1 part dust by mass, or less. The wet solids are treated with carbon dioxide to convert compounds, such as calcium hydroxide, to carbonates, such as calcium carbonate. The degree of carbonation is controlled so that the solubility of calcium becomes minimum for the dust being treated; this is also when hydroxyl and bicarbonate ions in solution are about at their minima. As the carbonation reactions occur, the water combined in hydroxides is released as free water so that the mixture becomes a slurry and the potentially soluble alkalies and sulfate (and any chlorides present) are released to the liquid phase. The solids are separated from the liquid, and the solids, which may be washed, provide a material suitable for return as feed to the kiln. The liquid, which contains the dissolved alkali compounds, is recycled to reclaim additional dust or treated to recover alkali salts when the alkali salts are sufficiently concentrated.While any source of carbon dioxide may be used, the preferred source is exit gases from the kiln. The gases are conditioned by condensation of water and removal of ammonium compounds, such as sulfate and chloride. The conditioning condensate may be treated to recover useful byproduct salts.

This invention is of a hybrid organoclay that consists of an organic chemical / phyllosilicate clay intercalate that has been ion-exchanged with quaternary ammonium compounds. Since this hybrid organoclay is hydrophobic, it can be washed in water to remove reaction salts and excess water soluble or water dispersible polymers to give a clean product via inexpensive means such as filtration. This allows a better dispersing composition to be prepared without the difficulties of isolation presented by prior art which uses energy intensive means to remove the bulk of the water from the final product and cannot be easily washed.

The invention is useful both as an ingredient to form nanocomposites and as a rheological additive.
