Advantage of Our Polyaluminium Chloride(PAC)
1. The purified water quality is better than the aluminum sulfate coagulant, and the clean water cost is 15-30% lower than that.
2. The formation of floc is fast, the sedimentation speed is fast, and the processing capacity of traditional products such as aluminum sulfate is large.
3. The alkalinity in the consumed water is lower than that of various inorganic coagulants, so that the alkali agent can be administered without or with little.
4, the adapted source water PH5.0-9.0 range can be agglomerated.
5. Low corrosivity and good operating conditions.
6. Solubility is better than aluminum sulfate.
7, the treatment of water with less salt increase, is conducive to ion exchange treatment and high purity water.
8. The adaptability to the source water temperature is superior to inorganic coagulants such as aluminum sulfate.
Introduction Of Polyaluminium Chloride(PAC)
Polyaluminum chloride is an inorganic polymer coagulant. Due to the bridging action of hydroxide ions and the polymerization of polyvalent anions, an inorganic polymer water treatment agent having a large molecular weight and a high charge is formed.
Applications of PAC
1. Urban water supply and drainage purification: river water, reservoir water, groundwater
2, industrial water purification
3. Urban sewage treatment
4. Recovery of useful materials in industrial wastewater and waste slag, promotion of sedimentation of coal powder in coal washing wastewater, and recovery of starch in starch manufacturing
5. Various industrial wastewater treatment: printing and dyeing wastewater, leather wastewater, fluorine-containing wastewater, heavy metal wastewater, oily wastewater, papermaking wastewater, coal washing wastewater, mine wastewater, brewing wastewater, metallurgical wastewater, meat processing wastewater
6, sewage treatment
7, paper sizing
8, sugar liquid refining
9. Cast molding

Production Process of Poly Aluminum Chloride
1.Drum drying type:
Alum purity around 28%, water insoluble content high,most used in waste water treatment and
2.Spray drying type
1) golden yellow color:
Alum purity can reach to 29%-31%, water insoluble content low, dissolved fast, used in drinking water treatment
2) white color powder:
Alum purity can reach to 29%-31%, water insoluble content low, dissolved fast, used in drinking water treatment, also can be used in paper production to increase the paper’s tension and whiteness
