●Polyaluminium chloride Principle
●Aluminum hydroxide and hydrochloric acid take polymerization reaction under the high temperature and high pressure
●AlCl3 take polymerization reaction in acidic medium, which Calcium aluminate powder works as  initiator
Polyaluminium chloride Progress
●Measure  reaction liquid：Take the moderate hydrochloric acid (or aluminium chloride solution) into the Metering tank  
●Reaction： warming then open the stiring and  put into aluminum hydroxide (calcium aluminate powder)
●Filter: Filter the material liquid after reaction with the plate-frame  to the finished product pool for cooling.
●transformed material: transformed to finished product pool , then drying treatment.
