    Polyaluminium Chloride
    Product category: Water treatment agent/flocculant
    English name: Polyaluminium Chloride
    CAS NO: 1327-41-9
    Molecular weight: 174.45 
    EC NO: 215-477-2

    Product introduction:

    Polyaluminium Chloride is a water-soluble inorganic polymer between ACL 3 and AL (OH) 3. The general chemical formula is [AL2 (OH) NCL6-NLm], where m represents the degree of polymerization and n represents the degree of neutrality of PAC products. The color is yellowish brown or light yellow, dark brown, dark gray resin like solid. The product has strong bridging and absorption properties. During hydrolysis, physical and chemical processes such as coagulation, adsorption and precipitation occur.

    The fundamental difference between polyaluminum chloride and traditional inorganic coagulants is that the traditional inorganic coagulants are low molecular crystalline salts, while the structure of polyaluminum chloride is composed of multiple carboxyl complexes with various forms, which has fast flocculation and sedimentation speed, wide range of applicable PH values, no corrosiveness to pipeline equipment, obvious water purification effect, and can effectively support the color and quality of SS, COD, BOD, arsenic, mercury and other heavy metal ions in the water. This product is widely used in drinking water Industrial water and sewage treatment.

    usage method:
    1. Dissolve the solid product into liquid by adding water in 1:3, and then add 10-30 times of clear water to dilute it to the required concentration before use.
    2. The dosage can be determined according to different turbidity of raw water. Generally, when the turbidity of raw water is 100-500mg/L, the dosage is 10-20kg per thousand tons.
    Packaging and storage:
    1. Lined with plastic bag, the outer layer is packed with plastic film woven bag, each bag weighs 25kg.
    2. Store in a cool, dry place and protect from the sun and rain.
