Aluminum ash reacts with sodium hydroxide to produce sodium aluminate solution, and then hydrochloric
acid is used to adjust the pH value to produce polymerized aluminum chloride solution.
Frequently Asked Questions
What is Polyaluminium Chloride?
Polyaluminum chloride (PAC) is an inorganic substance, a new water purification material, inorganic
polymer coagulant, referred to as polyaluminum. It is a water-soluble inorganic polymer between AlCl3
and Al(OH)3. The color is yellow or light yellow, dark brown, dark gray resinous solid. The product has
strong bridging and adsorption properties. During the hydrolysis process, physical and chemical
processes such as coagulation, adsorption and precipitation will occur. The fundamental difference
between polyaluminum chloride and traditional inorganic coagulants is that traditional inorganic
coagulants are low-molecular crystalline salts, while the structure of polyaluminum chloride is composed
of polyhydric carboxyl complexes with variable shapes, and the flocculation and precipitation speed is
fast, suitable for The pH value range is wide, non-corrosive to pipeline equipment, and the water
purification effect is obvious. It can effectively remove the color SS, COD, BOD and heavy metal ions
such as arsenic and mercury in water. This product is widely used in drinking water, industrial water
and sewage treatment. field.
