Polyaluminum chloride has made remarkable achievements in environmental pollution control Polyaluminum chloride is a highly efficient water purifying agent capable of sterilizing, deodorizing, decoloring, etc., because of its outstanding characteristics, wide range of application, and the dosage can be reduced compared with the traditional water purifying agent More than 30%, the cost savings of more than 40%, and can also be used to purify drinking water and tap water special water treatment, it has now become the recognized excellent water purification agent. Polyaluminum chloride to high-quality calcium aluminate powder and aluminum hydroxide powder as the main raw material through a series of processing skills for the inorganic polymer. After polydimethylsalicylic acid, the differentiation activity is rapid and rapid, without any additives, regardless of water temperature and water quality. It is also very easy to use: the original purification equipment can be used, the aluminum chloride mixed with water and dissolved evenly, and then put into operation in the water, the water purification is usually the amount of its raw water ten millionth, that is, every thousand Tons of water dosage 15KG, accurate use, according to the region's water turbidity and content are not the same to find the best dosage. Polyaluminum chloride solution flocculation effect, the accumulation of debris in the water and sludge, played a very good solid-liquid effect from the separation of the sludge into the sludge pool, with a frame filter press dry out , While the supernatant flows into the central pool, through the central pool and then by raising the pump to quartz sand filter tank.
