Polyaluminium chloride (PAC) is a new type high efficiency inorganic polymer coagulant, adopting advanced manufacturing technique and quality raw material, show the features of low impurity, high molecula weight, and superior coagulating effect.
Products Types
1. Poly aluminium Chloride 30% PAC S
1) Colour: White or Milk White colour softer powder
2) Produce process: Spray dry process
3) Basicity: At 30-70 %
4) Water insoluble matter: Lowest at 0.1%max
5) Iron content (Fe+): None
6) lowest heavy metal content, health
7) The solution: Is colourless liquid
8) Used for drinking water treatment and paper mills as retention agent, and paper remove electric charge and cosmetic industry.
Advantages of White Polyaluminium Chloride:
1. PAC reacts faster than aluminium sulphate because of its polymeric structure which allows a higher coagulation effi ciency
2. The formed fl ocs are bigger which means a faster sedimentation. Moreover, PAC remains effective over a wider turbidity range and even at very low temperatures
3. Lower quantities of residual aluminium in water (compared with the analogous value with aluminium sulphate) reducing consequently health problems (Alzheimer)
4. Reduced cleaning frequence of the fi lters (longer runs in the sand fi lters)
5. PAC consumes less alkalinity than the other coagulants. In most cases, there is no need of alkalinity addition for an effective flocculation, so additional pH correction chemicals aren't necessary
6. Lower doses are required for equivalent results in comparison with aluminium sulphate
7. PAC remains effi cient over a larger pH range
8. Less sludge production compared to the other coagulants.
Packing:
25kg/polypropylene woven bags with inner plastic bag, 25kg/PE bag.
