What is the relationship between polyaluminium chloride and water? Polyaluminum chloride manufacturers PAC is an inorganic polymer coagulant, due to the bridging effect of hydroxide ions and polyvalent anion polycation effect of the production of larger molecular weight, higher charge inorganic polymers Water treatment agent. Polyaluminium chloride (English name for Polyaluminium Chloride), referred to as PAC. Also commonly known as basic aluminum chloride or coagulant, it is a water-soluble inorganic high molecular polymer between ALCL3 and AL (OH). The product has strong bridging adsorption properties, in the hydrolysis process, with the onset of agglomeration, adsorption and sediment and other physical and chemical processes. The product is widely used in tap water production, which can effectively remove water turbidity, color, heavy metal ions and trace organic poison. Poly (co) aluminum chloride flocculation performance as follows: a, colloidal substances in water strong electric neutralization. b, hydrolyzate of water suspended solids excellent bridging adsorption. c, the selective adsorption of dissolved substances. Polyaluminum chloride performance aluminum chloride manufacturers a, purified water better than aluminum sulfate flocculant, water purification costs compared with 15-30% lower. b, rapid formation of flocs, settling speed, processing capacity than the traditional products such as aluminum sulfate. c, water consumption alkalinity lower than a variety of inorganic flocculant, which can not vote or less cast alkali. d, to adapt to the source water PH5.0-9.0 range can be condensed. e, corrosive, good operating conditions. F, solubility better than aluminum sulfate. g, treatment of salt in the water increased less conducive to ion exchange treatment and high purity water. h, adaptability to source water temperature is superior to inorganic flocculant such as aluminum sulfate. Polyaluminum chloride type classification Polyaluminum chloride is divided into two forms a, liquid aluminum chloride is not dried form, there is no dilution, loading and unloading easy to use, the advantages of relatively cheap price, the disadvantage is the transport needs tankers, Unit transportation costs increase (equivalent to 2-3 tons of liquid per ton of liquid) b, solid PAC after drying form, easy to transport advantages, do not need tanker, the disadvantage is the use of diluted also need to increase the intensity of work. Process Category a, drum-type poly (co) aluminum chloride aluminum content in general, high water-insoluble matter, used for sewage treatment. b, plate and frame poly (co) aluminum chloride content is high, low water insoluble, for sewage treatment and drinking treatment. c, spray-dried poly (aluminum) aluminum chloride content, low water-insoluble, fast dissolution. For drinking water and higher standard water treatment.
