Polyaluminium chloride
Molecular formula: [AL 2(OH)nCL6-n], polyaluminium chloride is an aprotic polymeric electrolyte coagulant with multivalent ions, which is an intermediate hydrolysis product between aluminum trichloride and aluminum hydrochloride. It is an intermediate hydrolysis product between aluminum trichloride and aluminum hydrochloride. Due to the bridging effect of chloride ions and the polymerization of multivalent ions, it generates inorganic polymeric water treatment agents with larger molecular weight and higher charge.

Detailed description
Molecular formula: [AL 2(OH)nCL6-n]
Property: Polyaluminium chloride is an aprotic polymeric electrolyte coagulant with multivalent ions, which is an intermediate hydrolysis product between aluminum trichloride and aluminum hydrochloride. It is an intermediate hydrolysis product between aluminum trichloride and aluminum hydrochloride. Due to the bridging effect of chloride ions and the polymerization of multivalent ions, it generates induction polymer water treatment agent with higher molecular weight and higher charge.
Uses: River water, reservoir water, groundwater purification, industrial water purification, urban sewage treatment, sludge treatment, coal washing, paper sizing, cosmetic materials and catalytic carrier, printing and dyeing, leather, brewing, meat processing, mining, oil refining and heavy metal industrial sewage treatment. Highly toxic heavy metals and fluorine wastewater treatment.
Packing: Solid: should be unloaded lightly to avoid package breakage, polyethylene laminated outer bag, lined with inner film, 25kg per bag, not to be transported or stored with harmful drugs. Dry at room temperature.
Storage and transportation: Liquid: Six months storage period for liquid products. Transported in sealed cans or plastic containers: Solids should be lightly loaded and unloaded to avoid package breakage, not to be transported or stored with harmful drugs.
Features: chemically stable at room temperature, non-toxic and harmless, high water purification safety, fast reaction, low dosage, fast and large alum flower formation, fast quality and dense settlement, good filterability, can improve equipment utilization, low treatment cost, low labor intensity. Applicable raw water PH value range is wide, in the PH value 4-12 range can be coagulated, PH value 6-8 best. Strong adaptability of treated water bodies, suitable for the treatment of various water bodies, high turbidity of water purification effect is particularly obvious. Can not add
Alkaline or other coagulants. It also solves the problem that other agents cannot easily treat low turbidity water and low temperature water (below 4 degrees) with poor response and slow effect. Good water solubility, no side effects from overdosing, easy to operate and manage, non-corrosive to water treatment equipment and pipes.
Usage: According to the different conditions of raw water, the general amount of water purification cast; solid 3-30pm, liquid products 10-100ppm dosing according to the best amount of dosing, and in use to observe the adjustment. If the precipitation pool alum flower is small and the residual turbidity is large, the dosage is too small, if the precipitation pool alum flower is large and upturned and the residual turbidity is high, the dosage is too large and should be adjusted appropriately.
