    摘要： Provided are methods for substantially removing organic substances from an aqueous solution, wherein the aqueous solution is contacted with a synthetic hydrated calcium silicate. Components that can be removed from aqueous solution include bacterial, plant, algal and fungal components. Exemplary components include endotoxins. The aqueous solution comprises, for example, water, a chemically buffered solution, a pharmaceutical solution, a solution comprising a nutritional supplement, a culture medium, or a growth medium. Other examples include pharmaceutical compendial water and non-compendial water. In one embodiment of the method, the pH of the aqueous solution is maintained at a selected pH to promote the separation, for example, about pH 5.5 to 9.5, or, e.g., about pH 5.5 to 7.5.

    摘要： Aqueous slurries of fine coal are dewatered by a process which comprises mixing an organopolysiloxane with the slurry, separating the slurry to recover the fine coal and further drying the fine coal, if desired. The use of water-soluble organopolysiloxanes or water-emulsifiable organopolysiloxanes provides improved separating and/or improved drying of fine coal in the dewatering process that is disclosed.

    摘要： Among flocculating agents reacting in a neutral region and also leaving treated water also in neutral region, a flocculating agent is proposed, which can be used simply and may carry out effective cleaning of mud water in particular.A flocculating agent is proposed, which is a flocculating agent in powder form and exhibiting a pH of 5 to 9 when added to pure water, containing in a mixed state an acidic powder comprising porous particles obtained by adsorbing a metal constituent and an alkaline powder comprising porous particles obtained by adsorbing calcium phosphate.
