Poly aluminum Chloride referred to as PAC. Often called Basic or a coagulant such as aluminum chloride, which is between ALCL3 and AL (OH) 3 ,as a water-soluble inorganic polymers, the chemical molecular is [AL2 (OH) NCL6 - NLm] ,where m on behalf of polymerization degree, n said that the neutral level of PAC products. The color is yellow or light yellow, dark brown, dark gray resin-like solid. The product has a strong bridge adsorption performance, during the hydrolysis process, Occurs with cohesion, adsorption and precipitation and other physical chemical processes.
PAC with the traditional inorganic coagulant, which two the fundamental difference is the traditional inorganic coagulant for the low-molecular weight crystalline salt, while the PAC structure from the multi-carboxyl complex form of variable composition, coagulation and sedimentation speed, application PH value range is wide, non-corrosive to the plumbing, water purification effect obviously, can effectively support In addition to the water-color quality SGS, COD, BOD, and arsenic, mercury and other heavy metal ions, the product is widely used in drinking water, industrial water and wastewater treatment filed.
1. The purification effect of high turbidity water is particularly obvious, no alkaline assistant or other assistant is required;Easy sedimentation; 2. Wide range of investment, no side effects; 3. High safety and low corrosion; 4.Suitable for wide PH value, easy operation, low cost, easy storage and transportation.
In water treatment, coagulation flocculation involves the addition of compounds that promote the clumping of fines into larger floc so that they can be more easily separated from the water. Coagulation is a chemical process that involves neutralization of charge ... Coagulation is affected by the type of coagulant used, its dose and mass; pH
flocculation are used to separate the suspended solids portion from the water. ... Coagulant chemicals with charges opposite those of the suspended solids are added to the ... These stages are followed by sedimentation, and then filtration
