30% Polyaluminum Chloride
30% polyaluminum chloride product overview:
30% polyaluminum chloride is a kind of water purification material, inorganic polymer coagulant, also known as polyaluminum or PAC in English. It is an inorganic polymer water treatment agent with large molecular weight and high charge produced due to the bridging action of hydroxide ions and the polymerization of multivalent anions.
In terms of morphology, it can be divided into solid and liquid.
The solid can be divided into brown, beige, golden yellow and white according to the color. The liquid can be colorless and transparent, yellowish, light yellow to yellowish brown. Polyaluminum chloride of different colors also has great differences in application and production technology.
30% polyaluminum chloride product specification:
Appearance: Yellow or light yellow powder
Alumina content%: 30-32
Basicity%: 40-90
Water insoluble content%: <0.1
Applications fields of 30% polyaluminum chloride:
1. mainly used for purification and treatment of drinking water; Urban water supply and drainage purification: River water, reservoir water and groundwater.
2. Purification of industrial water supply.
3. Urban sewage treatment.
4. recovery of useful substances in industrial wastewater and waste residue, promotion of coal dust deposition in coal washing wastewater, and recovery of starch in starch manufacturing industry.
5. various industrial wastewater treatment: printing and dyeing wastewater, leather wastewater, fluorine-containing wastewater, heavy metal wastewater, oily wastewater, paper-making wastewater, coal washing wastewater, mining wastewater, brewing wastewater, metallurgical wastewater, meat processing wastewater, sewage treatment.
Advantages of 30% polyaluminum chloride:
Due to the advantages of spray drying, such as good stability, wide water area, fast hydrolysis speed, strong adsorption capacity, large alum formation, fast quality density and sedimentation, low turbidity of outlet water, good dehydration performance, etc., the dosage of spray type polyaluminum chloride is reduced under the same water quality, especially when the water quality is poor, the dosage of spray drying products can be reduced by half compared with roller drying polyaluminum chloride, It not only reduces the labor intensity of workers, but also reduces the water production cost of users. Polyaluminum chloride, referred to as polyaluminum chloride, or PAC. It is formed by reaction polymerization of raw materials with high degree of use using the most advanced production process at present. All the quality indicators have reached or even exceeded the requirements of the national standard gb15892-2009. Polyaluminum chloride is processed by spray drying process, so it can also be called spray drying polyaluminum chloride. Characteristics of polyaluminum chloride product: it has the characteristics of fine powder, uniform particle, easy to dissolve in water, good flocculation effect, stable purification, small dosage and low cost. Suitable for drinking water purification, urban water supply purification and industrial water supply purification; It is applicable to source water of various turbidity, with a wide range of pH, large and fast alum formation and fast sedimentation.
30% polyaluminum chloride product features:
1. Without adding other additives, the flocs form quickly and coarsely, have high activity, and precipitate quickly. The purification effect on high turbidity water is particularly obvious.
2. The applicable pH value range is wide, and the pH value in the reduced raw water is small, so it has no corrosive effect on the pipeline and equipment. The suitable pH value range is wide (5-9), and the pH value and alkalinity of the treated water decrease little.
3. It can decolorize wastewater, remove COD, BOD and SS, and has strong decontamination ability. The water purification effect is 4-6 times that of Al 2 (so 4) 3 and 3-5 times that of Al CL 3. Small dosage and high efficacy; Low cost and high benefit.
4. When used for low-temperature water treatment, stable sedimentation effect can still be maintained, and the dosing range is wide. Excessive dosing is not easy to produce side effects, which is conducive to workers' operation.
30% polyaluminum chloride packaging and storage:
1. Liquid products can be transported in tank cars or plastic barrels, and can be stored in the pool with a storage period of one year.
2. Solid products are packed in plastic woven bags lined with plastic film bags, with a net weight of 25kg each.
3. Solid products are easy to absorb moisture and deliquesce (after deliquescence, the use effect will not be affected), and should be stored in a ventilated and dry place. The storage period of solid products is one year.
4. This product shall not be mixed with hazardous substances for storage.
