Water Purifying Agent Chemical PAC 30% Poly Aluminum Chloride
PAC is a kind of inorganic macromolecule flocculant, the color is yellow or pale yellow, dark brown, dark gray resin solid. Through the hydroxyl ion bridging function and the polyvalent anion polymeric function, it produces large molecular and high electricity inorganic macromolecule. It adapts a wide pH range of 5.0~9.0, and the best is between 6.5~7.6. The product is high-efficient, cheap and nontoxic inorganic high molecular compound. It's easily soluble in water. In the hydrolytic process, it is accompanied with the chemical processes such as electrochemistry, coagulation, absorption and precipitation. The product has the features including wide applicable range of PH value, large granule, and quick speed in sedimentation. It's widely used in treating the domestic drinking water, domestic sewage and industrial waste water.

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
APPLICATION
1. Purifying drinking water, sewage.
2. Industrial water purification, industrial wastewater, mining, oil field injection water, metallurgy, coal washing, metallurgy industry, mine, pharmacy, paper-making, and purification of the waste water containing fluorine, oil and heavy metals leather and all kinds of chemical waste water treatment.
3. Reclaiming coal from coal-washing waste water and kaolin in ceramic industry
4.Industrial production: Paper sizing, dye printing, bleaching and dyeing, medicine and other industries.
5. In artificial coal industry, it is used for separating coal and water with excellent effect. In the oil refining industry, for oil and water separation.
6. Refining of pharmaceuticals, glycerin and sugar.
