Polyaluminium chloride is a kind of non-toxic, harmless and odorless white, light yellow or yellow liquid or powdered resin-like hygroscopic solid that is soluble in water.

　　Chemical name: Polyaluminium Chloride (PAC)

　　Molecular formula: [AL2(OH)nCl6-n]m 1

　　Polyaluminium Chloride (Drinking Water Grade) is a kind of new high-efficient inorganic polymer coagulant. This product is produced with aluminum hydroxide, synthetic hydrochloric acid and calcium aluminate powder through advanced process. Although it is low in price, it has good flocculating effect, and its water purification effect is better than traditional inorganic salts coagulants such as aluminum sulfate and ferric salt. Solid products are light yellow, yellow or brown powders produced through spray drying technique. Besides, we can also provide relevant liquid products.

　　I. Executive standard: drinking water grade GB15892-2009, and industrial grade GB/T22627-2008 for polyaluminium chloride

　　II. Flocculation properties and performance

　　▲ Less amount of use; quick formation of flocculating constituent and quick sedimentation; low residual aluminum and excellent water quality after purification.

　　▲ Small consumption of alkalinity in water, and low reduction to the PH value of water

　　▲ Extremely soluble; containing less insoluble substances in aqueous solution; low corrosion

　　▲ Applicable to wide PH value range; applicable to PH values within 5.0-9.0

　　▲ Highly adaptable to various turbidities, alkalinities and temperatures.

　　▲ All quality indexes of the product, especially the heavy metal index, are conforming to the requirements of GB15892-2009 standard.

　　III. The most applicable areas

　　▲ Drinking water treatment and pretreatment for preparation of pure water

　　▲Oilfield back - injection water treatment
