Polyaluminium chloride is a coagulant chemical added to water to help remove small particles of dirt and contaminants that may make people sick and block water system filters. It is suitable for wastewater treatment in various industrial fields, such as domestic sewage, papermaking, chemical industry, electroplating, printing and dyeing, aquaculture, mineral processing, medicine and other industries, as well as treatment of rive and lake water. Drinking grade polyaluminium chloride(PAC 30%) can be used in drinking water treatment.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Polyaluminum chloride is immediately dissolved in water. During the dissolution process, hydroxide ions release a large amount of positive charges to adsorb negatively charged ions in the water. The flocs form fast and coarse with high activity, and settle quickly, so as to achieve the purpose of decomposing and purifying sewage. The purification effect of high turbidity water is obvious.<\/p>\n

The working principle of polyaluminum chloride is mainly to destabilize the edema fine suspended particles and colloidal ions, aggregate, flocculate, coagulate, through the mechanism of adsorption electric neutralization, adsorption bridging, compression of double electric layer, and sediment net trapping, so as to achieve the purification treatment effect.<\/p>\n

    \n
  1. The role of adsorption bridging. It refers to the adsorption and bridging of polymer substances and colloidal particles. It can also be interpreted as understanding that two large rubber particles of the same size are connected together due to a different size rubber particle.<\/li>\n
  2. The effect of compression the electric double layer. It means that the structure of the micellar electric double layer determines the concentration of counter ions on the surface of the colloidal particles. As the distance from the surface of the colloidal particles increases, the concentration of counter ions decreases, which is finally equal to the ion concentration in the solution.<\/li>\n
  3. Sediment net catching mechanism.It means that when metal salts (such as aluminum sulfate or ferric chloride) or metal oxides and hydroxides are used as coagulants, when the dosage of polyaluminum chloride is large enough to quickly precipitate metal hydroxides (such as Al(OH) )3, Fe(OH)3, Mg(OH)2 or metal carbonate (such as CaCO3), the colloidal particles in the water can be caught by these precipitates when they are formed.<\/li>\n<\/ol>\n

    Polyaluminium chloride PAC<\/a> is a kind of water treatment chemical with a wide range of uses. It has the advantages of fast flocculation, rapid sedimentation, good solubility and low water purification cost. As a reliable polyaluminium chloride manufacturer in China, we can guarantee the high quality and competitive price.
