Introduction:
Polyaluminium chloride, PAC for short, is a kind of cationic polymer flocculant with polyhydroxy and polynuclear complex. The appearance of the solid product is light yellow or red yellow powder. Due to the different number of hydroxyl groups in the molecules, when polyaluminium chloride is added to the turbid source water, it will continue to hydrolyze under the pH condition of the source water. In the hydrolysis process, there are a series of physical and chemical processes such as condensation, adsorption and precipitation, so as to achieve the purpose of purification.
characteristic:
The remarkable characteristics of this product are obvious water purification effect, fast flocculation and sedimentation speed and wide pH range; It has low corrosivity to pipeline equipment and can effectively remove SS, COD, BOD, arsenic, lead, mercury and other heavy metal ions in water. It has the advantages of low cost, high efficiency, small dosage, simple operation, saving manpower and material resources. The product can be widely used in drinking water, industrial water and sewage treatment.
