Polyaluminum Chloride Product Description
Polyaluminum chloride is an inorganic polymer coagulant, also referred to as polyaluminum chloride or polyaluminum, and the English abbreviation is PAC. It is produced due to the bridging effect of hydroxide ions and the polymerization of polyvalent anions. Inorganic polymer water treatment agent with larger molecular weight and higher electric charge. In terms of form, it can be divided into solid and liquid, and solid is divided into tan, yellow and white according to different colors. Polyaluminum chloride of different colors also has great differences in application and production technology
The main coagulant in sewage treatment is polyaluminum chloride PAC, and the main flocculant in sewage treatment is polyacrylamide PAM.
Polyaluminum chloride PAC is a commonly used coagulant in sewage treatment. Its functions in sewage treatment are oil removal, decolorization, turbidity removal, suspended solids removal, and fluoride removal.
Polyaluminum chloride PAC is divided into liquid polyaluminum chloride PAC and powder polyaluminum chloride PAC. Powder polyaluminum chloride PAC is suitable for long-distance transportation and has low cost. Liquid polyaluminum chloride PAC is suitable for nearby purchase and use, and is easy to use
superiority
PAC polyaluminum chloride has the advantages of good spray drying stability, wide adaptability to water, fast hydrolysis speed, strong adsorption capacity, large alum formation, fast mass density precipitation, low effluent turbidity, and good dehydration performance. The dosage of spray-dried polyaluminum chloride is reduced, especially in the case of poor water quality, the dosage of spray-dried products can be reduced by half compared with drum-dried polyaluminum chloride, which not only reduces the labor intensity of workers, but also More importantly, it reduces the cost of water production for users. In addition, spray-dried products can ensure safety, reduce water accidents, and are very safe and reliable for residents' drinking water. Using the most advanced production technology at present, it is formed by reaction polymerization with high-efficiency high-quality raw materials. All quality indicators meet or even exceed the requirements of the national standard GB15892-2009. Polyaluminum chloride is processed by spray drying process. Therefore, it can also be called high-efficiency spray drying polyaluminum chloride. Features of polyaluminum chloride: Kaibiyuan brand PAC products have fine powder, uniform particles, and are easily soluble in water. , good flocculation effect, efficient and stable purification, less dosage, low cost and so on. It is suitable for drinking water purification, urban water supply purification and industrial water supply purification.
Polyaluminum chloride PAC concentration ratio method:
According to the daily use of solid polyaluminum chloride PAC, when diluting it into liquid, summarize and share several commonly used polyaluminum chloride PAC concentration ratio methods, hoping to help everyone!
The first step is to do a small test to obtain the best dosage according to the raw water condition. The configuration of the small test solution is generally 2 to 5% by weight. For example, with 3% solution: weigh 3g of polyaluminum chloride PAC solid, put it into a 200ml graduated cylinder, add about 50ml of water, after dissolving, add water to dilute to 100ml scale, and shake wel
In the second step, when producing polyaluminum chloride PAC, it can be mixed and dissolved according to the weight ratio of polyaluminum chloride PAC solid: water = 1:9 to 1:15. The solution with alumina content less than 1% is easy to be hydrolyzed, which will reduce the use effect, and it is difficult to add evenly if the concentration is too high.
The third step is to add the medicine according to the optimal dosage obtained by the small test. If the alum in the sedimentation tank is small and the residual turbidity is large, the dosage is too small; if the alum in the sedimentation tank is large and turned up, and the residual turbidity is high, the dosage is too large and should be adjusted appropriately.
Water-insoluble matter of PAC polyaluminum chloride: Using plate and frame filter press technology, the mass fraction of solid water-insoluble matter is below 0.3%, and the mass fraction of liquid water-insoluble matter is below 0.1%, which can ensure the smooth flow of the user's pipeline. At the same time, the utilization rate of drugs can be improved, which cannot be achieved by the natural sedimentation method. Polyaluminum chloride PAC-01 (pale yellow powder, spray drying): used for drinking water treatment and wastewater treatment. Polyaluminum chloride - is one of the star products in the series of water treatment chemicals. Polyaluminum chloride integrates many advantages such as ordinary polyaluminum chloride, spray type polyaluminum chloride, and high-efficiency polyaluminum chloride for papermaking. Efficient product. All water treatment chemicals are subject to the latest national standard, and water treatment chemicals are subject to GB15892-2009.

Characteristics of spray drying
The characteristics of Jiaxin water purification brand high-efficiency polyaluminum chloride pressure spray drying polyaluminum chloride are mainly determined by the working principle of the pressure atomizer, which makes this drying system have its own characteristics. Since the product obtained by pressure spray drying is in the form of porous particles or hollow particles, the use of pressure spray drying is mostly for the purpose of obtaining granular products, and the obtained granular products have excellent dustproof performance and flow performance. Due to the large contact area between the product and water, the wetting performance is better than that of powder products, and the speed of water purification is significantly higher than that of powder products. Well received by users.
Spray granulation is to atomize polyaluminum chloride into tiny particles while drying, which has good application performance. Polyaluminum chloride is a water-soluble substance with good thermal stability and high solubility. During the drying process, a 40%-50% solid content polyaluminum chloride solution is introduced into a high-pressure pump, and the After entering the atomizer in the dryer for atomization, it is dispersed into tiny mist droplets, and the mist droplets are dried to obtain granular products, so that drying and granulation are completed at the same tim
Polyaluminum chloride performance characteristics:
1. Polyaluminum chloride has large molecular structure, strong adsorption capacity, less dosage and low processing cost.
2. Good solubility, high activity, large flocs formed by coagulation in the water body, fast sedimentation, 2-3 times greater purification capacity than other inorganic flocculants.
3. It has strong adaptability and is less affected by the pH value and temperature of the water body. The purified raw water reaches the national drinking water standard. The content of cations and anions in the treated water is low, which is conducive to ion exchange treatment and the preparation of high-purity water.
4.It is less corrosive and easy to operate, which can improve the labor intensity and labor conditions of the dosing process
5. Good coagulation effect can be achieved for raw water with serious pollution or low turbidity, high turbidity and high chroma.
