Abstract:
     This invention is a method for producing the flocculent of polymeric aluminium chloride. In the method, the waste hydrochloric acid containing aluminium, which is exhausted during the industrial corrosion of aluminium, and amononia water are used as raw materials; the aluminium hydroxide generated from above reaction is added into the waste hydrochloric acid containing aluminium again, to generate polymeric aluminium chloride with a PH value of 2.5-3.5. It can be used in the especial processing of edible water quality. Its by-product, ammonium chloride, has very high purity and can be used in food industry.
