  Brief intro.
  
  Technical standard： GB15892-2003
  Color：Beverage grade PAC is golden, industrial PCA is red brown.
  
  Features
  1, fast formed floc good activity and filtration.
  2, alkaline additives is unessential; in case of deliquescence, the effect is the same.
  3, Broad applicable PH range, strong adaptability and wide applications
  4, treated water contains less salt.
  5, can remove heavy metals and radioactive substances from water
  

  Uses
  
  It offers wide applications in the purification of water, including sterilization, deodorization, degreasing, removing fluorine, aluminum, chrome, turbidity, heavy metal salts and radioactive contaminants.
  1, purifying drinking water and domestic sewage.
  
  2, purification of industrial water: industrial wastewater, mining, oil field injection water, purifying water and remaking, metallurgy, coal washing, leather and all kinds of chemical sewage treatment.
  3, industrial application; sizing of paper, printing-dyeing and bleaching-dyeing, accelerating additive of cement, hardener of precision casting, adhesive of refractory viscosity, refining of glycerin, wrinkle-free of cloth, medicine, cosmetics and other industries; the waste water can be recycled.
  
  4, It offers good effect in in the refining industry.

  Usage
  
  1, dissolved it in water in 1：3, and then diluted solution in 20 to 30 times of water 。
  2, determining the dosage according to your demands, i.e. dosage can be 10-20kg/1000 tons when turbidity is 100-500mg/L
  
  Packing & storage
  
  1, Net wt 25kg in plastic bag lined plastic film woven bag
  2, kept in cool and dry place, avoid insolation and rain, no mix with inflammable/explosive/radiating substances, or chemicals
  3, ．in case of deliquescence, the effect is the same. But it may be dissolved in water when it absorbs moisture
