Product Description

Poly aluminium chloride (PAC), referred to as polyaluminum, is an inorganic polymer coagulant. It is produced due to the bridging effect of hydroxide ions and the polymerization of multivalent anions. It is an inorganic coagulant with a larger molecular weight and higher charge. Polymer water treatment chemicals. Due to its advantages of small dosage, large flocs, fast floc settling speed, low cost, and good coagulation effect, so polyaluminum chloride (PAC) is currently widely used in water and sewage treatment at home and abroad.

The color of poly aluminum chloride PAC powder is generally white, light yellow, or tan. Polyaluminum chloride with an aluminum trioxide content within the national standard range of 27% to 30% is mostly khaki, to yellow, or light yellow solid powder. These types of poly aluminium chloride have relatively good water solubility, and will be accompanied by a series of physical and chemical changes such as electrochemistry, coagulation, adsorption and precipitation during the dissolution process. The flocs will form quickly and thickly, with high activity and rapid precipitation. The purification effect on high turbidity water is obvious.

Performance Advantages of Poly Aluminium Chloride (PAC)

As an efficient water purifier, poly aluminium chloride (PAC) can sterilize, deodorize, decolorize, etc. Due to its outstanding characteristics and advantages and wide application range, the dosage can be reduced by more than 30% compared with traditional water purifiers, and the cost can be saved by more than 40%. PAC chemical has become an excellent water purifier recognized at home and abroad. In addition, poly aluminum chloride can also be used to treat special water quality such as purifying drinking water and tap water supply. Its advantages are specifically reflected in the following aspects:

  • The purified water quality is better than aluminum sulfate flocculant, and the water purification cost is 15-30% lower than it.
  • The flocs form quickly and settle quickly, and have greater processing capacity than traditional products such as aluminum sulfate.
  • The alkalinity of the consumed water is lower than that of various inorganic flocculants, so no or less alkali agent can be added.
  • The adaptable source water pH range is 5.0-9.0 and can be condensed.
  • Less corrosive and good operating conditions.
  • Solubility is better than aluminum sulfate.
  • There is little increase in salt content in the treated water, which is beneficial to ion exchange treatment and high-purity water production.
  • Its adaptability to source water temperature is better than inorganic flocculants such as aluminum sulfate.

PAC poly aluminum chloride can be used to purify domestic drinking water, industrial water, domestic sewage, industrial wastewater and sludge dehydration treatment. In addition, PAC chemical can also be used in paper, pharmaceutical, leather, casting and other industries.

Drum type process: The aluminum content is average and the water-insoluble matter is high, and it is mostly used for sewage treatment.

Plate and frame process: The high aluminum content and low water-insoluble matter. Used for municipal sewage treatment and domestic sewage treatment.

Spray drying process: The high aluminum content and low water-insoluble matter, fast dissolution rate, generally used for drinking water and higher standard water treatment. Under the same water quality, the dosage of spray-dried poly aluminum chloride will be reduced accordingly. Especially when the water quality is poor, the dosage of spray drying products can be reduced by half compared with drum drying polyaluminum chloride, which not only reduces the labor intensity of workers, but more importantly, reduces the user’s water production costs. In addition, spray drying products ensures safety and is very safe and reliable for residents’ drinking water.
