聚合氯化铝铁的专业知识（Professional knowledge of PAC） Poly aluminum ferric chloride (PACF) is a new compound amorphous inorganic polymer water purifying agent based on aluminum and iron (iron content is about 2-3%). Iron is a high valence iron, which forms a polynuclear complex after hydrolysis. At low temperatures, the alum flowers formed in water are more compact than those of alum. This is mainly due to the hydrolysis rate of iron salts. The hydrolysis process is very little affected by temperature. As the iron content is low, the pH of the water and the chroma of the effluent will not be too much. On the contrary, because of the color removal properties of aluminum salts, the water color is greatly reduced. Therefore, it has the characteristics and properties of PAC and ferric salts, and greatly reduces the water color. So it has the characteristics and characteristics of PAC and iron salts. The water purification difficulty of PAC at low temperature and low turbidity was overcome. Therefore, its water purification effect is obviously superior to the general water purification product. Properties of polyaluminum ferric chloride: 1, high efficiency: poly aluminum chloride ferric complex polymer, the molecular structure of large, strong adsorption capacity, water purification effect is superior to all traditional inorganic water purification agent. 2, less dosage: less corrosive to equipment and pipe, easy operation, small dosage, low purification cost. 3, fast: the raw water after the formation of floc size, precipitation speed, high activity, good filtration. Adaptability: the adaptability of various raw water is strong, the pH value of water is very small (pH value 6-9). No matter the turbidity of raw water or the concentration of wastewater pollutants, the purification effect is remarkable. Method for using polymeric aluminium chloride iron: 1, according to the raw water for the same situation, before use, you can do a small test to get the best amount of delivery. 2, pr
