Short Description:

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.

    Noted.png

    For arsenic, lead, cadmium, mercury and hexavalent chromium listed in the liquid products in the table, when the aluminum oxide content is more than 10.0%, it should be converted into aluminum oxide 10.0% products according to the actual content, and the magazine indexes should be calculated.


    Properties_.png

    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.

    Packaging:25KG/Lined with plastic bag, the outer layer is packed with plastic film woven bag.

    Usage Method.png

    1. 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.


    Storage_.png

    Store in a cool, dry place and protect from the sun and rain.
