Ploy-Aluminium-Chloride(PAC) is a new high efficient abio-macromolecule precipitator the molecule of it is between AlCl3 and Al(OH)3 which bond with hydroxy, the form is [Al2(OH)nCl6-n]m, here m≤10;n≤5。
PAC is water-solubility, has strong adsorbability, go with physical and chemical reaction such as electrochemistry, agglomeration, adsorption, deposition. It mainly used to regenerate drinking water or decontaminate industry sewage(which contnet oil or dyestuff), and some special sewage(which content radioelement, plumbum, chromium or fluorin).
  And it can used in exact founding, paper making, leather making induatry.Poly aluminum chloride(PAC) and Poly Aluminum Silicate is modified Poly Alumimum Chloride. PAC and PASI are composed of a series of aluminum ions with different polymerization degree and its main components are AL13O4(OH)24(H2O)127+,highly charged polymeric chain of aluminum, which has strong electrical neutralization and bridging coagulation to the colloid and microparticles in the water and can remove effectively turbidity , colority, heavy metals and poisonous organic compounds, PAC and PASI have good performances in applications such as: good flocculation, compact flocculation groups, rapid sedimentation and good adaptation for the quality of raw water. We have various classes of PAC for different purposes such as treating wastewater and purifying drinking water.
Purification of drinking water and industrial water;
Treatment of industrial wastewater and domestic sewage:
Dehydration of sludge:
Gelatinizer in paper-making.
