Polyaluminum chloride is a water purifier used very widely, almost can applied to all sewage,
The principle of action is to adsorb the pollutants in the water, then form fine crystals, so that its precipitation can achieve the goal of water purification.
The role and performance characteristics of polyaluminum chloride include following:
1. The purified water used with polyaluminum chloride is better than that with aluminum sulfate coagulant, and the cost of water purification is 15-30% lower.
2. The flocculation is fast in formation and sedimentation, and the processing capacity is greater than that of traditional products such as aluminum sulfate.
3, Compared with other inorganic coagulants， the consumption of water alkalinity is lower, so alkali is less need or no need.
4, Can be condensed in the suitable raw water with PH5.0-9.0.
5. Low corrosion and better to operate.
6. Better solubility than aluminum sulfate.
7. Less salt in treated water, which is conducive to ion exchange treatment and high purity water production.
8. Better adaptability to raw water temperature than inorganic coagulants such as aluminum sulfate.
