【China Aluminum Industry Net】Polyaluminum chloride water purification agent is a polyhydric, multi-nuclear complex cationic inorganic polymer flocculant. In the hydrolysis process, a series of physical and chemical processes such as agglomeration, adsorption and precipitation can occur, but the pH of the water is not changed, and the purpose of purifying the sewage is achieved.

The sewage discharged from the rubber factory is colorless, but it is turbid and accompanied by odor. The surface of the sewage floats with particulate matter and has a pH of 6. In the sewage of the glue factory, containing metal ions makes some manufacturers have headaches when choosing water purifying agents.

In the sewage treatment experiment of the glue factory, we took the sewage water and added an aqueous solution of a polyaluminum chloride purifying agent. After about 5 minutes, there was suspended Xuzhuang sediment in the sewage. After 10 minutes, the solution obviously accumulated in the bottom of the cup; 20 After a few minutes, the solution gradually became clear and a yellow-white precipitate appeared on the bottom of the cup; after 1 day, the solution was completely clear and transparent. The pH of the water does not change.

Through experiments, the polyaluminum chloride water purifying agent can effectively treat the sewage of the glue factory and reach the discharge standard. It has low corrosiveness to pipeline equipment and can well remove the COD, BOD, SS, and heavy metal ions in the water. Relative to other water purifier products, its cost is low, the amount is small, the operation is simple, and the treatment effect is obvious.
