Polyaluminium chloride

Production process

The product is made of aluminum hydroxide, calcium aluminate powder and hydrochloric acid. After heating reaction in the reactor with hydrochloric acid and aluminum hydroxide, calcium aluminate powder is used in the polymerization tank to continue to react to liquid aluminum chloride, which is dried by upper layer cleaning solution after several days of sedimentation.

characteristic

The purified water quality is better than aluminum sulfate flocculant, and the cost of purified water is 15-30% lower than that of the flocculant. The flocculation is formed quickly and the settling speed is fast, which is more capable of treatment than the traditional products such as aluminum sulfate. The alkalinity of the consumed water is lower than that of various inorganic flocculants, so it can not be put or less alkali. The suitable range of ph5.0-9.0 can be condensed. The salt content of the treated water is less, which is beneficial to ion exchange treatment and high purity water production. The adaptability to the temperature of the source water is better than that of the inorganic flocculants such as aluminum sulfate.

Technical indicators
