Polyaluminium chloride referred to as PAC, also known as aluminium chloride or coagulant, it is between AlCl3 and Al (OH) 3 between a water soluble inorganic polymer, the product has a strong bridging adsorption performance, during the hydrolysis process, accompanied by condensation, adsorption and sedimentation physical and chemical processes. Compared with other coagulants, it has many advantages such as wide adaptability, wide application, good precipitation performance, wide PH range and small pH value after treatment.
The mechanism of polymerization aluminum chloride in water is mainly in the form of AL13O4 (OH) 247+, coagulation mechanism which is mainly reflected in the following three aspects: A, the colloid in water strong electric neutralization; excellent bridging adsorption of B, hydrolysis of suspended matter; C, the dissolved substances selective adsorption.
Applicable scope: suitable for purifying drinking water, special water treatment of water supply, removing iron, removing cadmium, removing fluorine, except floating oil, etc. It is also suitable for industrial wastewater treatment, such as printing and dyeing wastewater, and is also widely used in papermaking, medicine, leather making and so on.
