Coagulants

Poly Aluminium Ferric Chloride (CAS No. 1327-41-9)

 

This product is inorganic macromolecular coagulant, which is made by poly aluminum chloride complexing with polymeric. Therefore, the molecular structure is enlarged; the capacity of neutralization and bridging adsorption is enhanced. It is an ideal chemical to treat heavily organic polluted raw water as well as low-temperature and low-turbidity, low-temperature and high-turbidity water.

 

Properties

  • It combines the coagulate advantage of aluminum salt and ferric salt; can lead to quick formation of close flocks and rapid precipitation.
  • It has wide-range adaptability to the waters at different temperature and a good solubility.
  • The dosage is smaller than that of other flocculants, which is better for improving the quality of treatment water.
  • It is suitable for the automatic dosing.

Note: The mass fractions of NH3-N, As, Pd, Cd, Hg and Cr6+ are calculated based on that of Al2O3 as 10.0%, when the concentration of Al2O3 is not 10.0%, the standard need to be calculated as multiple of 10.0%.


Application Method & Notes

  • The liquid product can be dosed directly or dosed after dilution. Dilution is necessary before dosing for the solid product. The normal dilution ratio for solid product is 2%-20%, and 5%-50% for the liquid product (based on weight percentage).   
  • The specific dosage is based on the flocculation tests and trials by the users. The usual dosage of the liquid production is 3-40g/ton, and of the solid product, 1-15g/ton.
  • The product can not be stored with other chemicals.
  • For the liquid product, we provide special tanks for transportation to the clients, and afford the storage tank. The solid product is packed in inner plastic bags and further in polypropylene woven bags, with each bag containing 25Kg.
  • The shelf life is six months for liquid product and year for the solid product. The product should be stored in a dry and ventilated place, but the effect will not be affected even if it gets wet.
