Description
Polymerized aluminum chloride (PAC) is an inorganic material, an emerging water purification material, inorganic polymer coagulant, referred to as polyaluminum. It is a water-soluble inorganic polymer between AlCl3 and Al(OH)3, which has a high degree of electro-neutralization and bridging effect on colloids and particles in water and can strongly remove micro-toxins and heavy metal ions, with stable properties. The color is yellow or light yellow, dark brown, dark gray resin-like solid.
The product has strong bridging adsorption performance, in the process of hydrolysis, accompanied by the occurrence of cohesion, adsorption and precipitation and other physicochemical processes. The fundamental difference between polymerized aluminum chloride and traditional inorganic coagulant is that traditional inorganic coagulant is low molecular crystalline salt, while the structure of polymerized aluminum chloride consists of multiple carboxyl complexes with variable morphology, with fast flocculation and precipitation speed, wide range of pH value, no corrosive to pipeline equipment, obvious water purification effect, and can effectively support the removal of color SS, COD, BOD and arsenic, mercury and other heavy metal ions in the water, which are widely used in drinking water, industrial water and sewage. The product is widely used in the field of drinking water, industrial water and sewage treatment.
