    摘要: Utilization of a cationic polymer as a settling aid in the recovery of the aluminum hydroxide and an anionic polymer to dewater the aluminum hydroxide prior to redissolution not only improves the process of making basic aluminum compounds by speeding settling and improving filterability, but also unexpectedly yields a product that has superior effectiveness as a water treatment chemical.According to the invention, a dilute solution of alum is neutralized with a base to a pH below about 6.0, preferably below 5.5, to form a suspension of aluminum hydroxide. A cationic polymer is then added to the suspension to assist in the settling of the aluminum hydroxide. When settling is substantially complete, the solution is decanted from the aluminum hydroxide and an anionic polymer is added to dewater the aluminum hydroxide. The dewatered material is collected as a filter cake containing amorphous aluminum hydroxide, the cationic polymer and the anionic polymer.The filter cake formed in this manner can be combined with aluminum sulfate or other aluminum species to form basic aluminum complexes. Surprisingly, however, the basic aluminum compounds formed from the filter cake are more effective in the reduction of water turbidity than comparable basic aluminum compounds formed without the use of the cationic and anionic polymers.

    摘要: A process of producing a flocculating agent useful for water purification technology and as a substitute for aluminium sulphate in the rosin sizing of paper is described. In this process, about 100-150 parts by weight, preferably about 130 parts by weight of hydrochloric acid, calculated as 100% HCl, and 140-200, preferably 160-190 parts by weight of a sulphate-containing, aluminium hydroxide-containing sludge, calculated on the solids content of the sludge, are mixed. To obtain the sludge, alkaline pickles used in the pickling of aluminium profiles in connection with the anodization of aluminium are neutralized with sulphuric acid or aluminium sulphate. The sludge may also contain up to about 10% by weight of aluminium hydroxide. The mixture is heated and stirred at a temperature of from about 80.degree. C. to the boiling point of the mixture, preferably 95.degree.-100.degree. C., for a combined time of about 3-15 hours, preferably about 4-6 hours. The reaction product is a substantially saturated aqueous solution of polyaluminium chloride having the presumed formulaAl.sub.a (OH).sub.b (SO.sub.4).sub.c Cl.sub.3a-b-2cwherein a, b and c may have the values 13, 34 and 1, respectively.
