Poly Aluminium Chloride is salt of Aluminium. It is oligomer. Because of its polymeric structure, it is more effective in water treatment compared to other Aluminium salt like Aluminium Sulphate and Sodium Aluminium.
It is produced by reaction of Alumina Hydrate and Hydrochloric, Acid
Manufacturing process
is consist of
- Hydrochloric Acid storage and feeding
- Alumina Hydrate storage and feeding
- Reaction in glass lined reactor under pressure and controlled temperature
- Cooling of crude product
- Filtration of crude product
- Storage of basic Poly Aluminium Chloride i.e. PAC 18
- Formulation of different grades of liquid products such as PAC10, PAC10 HB, and PAC 14
- Waste product recycle in the process
- Spray drying of liquid Poly Aluminium Chloride in to powder form
Uniqueness of process technology
- No liquid waste/pollution
- No solid waste as filter cake is recycled in the process
- Production process is automated
