Drum drying poly aluminum chloride
1, product name:
[Chinese name] commonly known as the purifying agent, also known as poly-aluminum chloride, abbreviated as poly-aluminum, the English name of PAC. And the Basic PAC, PAC belong to the same spray-drying water-related pharmaceutical. Is a multi-hydroxy, multi-core complex body of cationic inorganic polymer flocculant, solid product appearance solid yellow or white powder, its chemical formula is [AL2 (OH) nCL6-n] m. (equation, 1 ¡Ü n ¡Ü 5, m ¡Ü 10), and soluble in water, there is a strong bridge adsorption, during the hydrolysis process with electrochemistry, cohesion, adsorption and precipitation, and other physical chemical changes, the final generation [AL2 (OH) 3 ( OH) 3], so as to achieve the purpose of purification.
2, the main features:
The product, compared with other coagulants, has the following advantages: wide range of applications to meet the wide range of water-based. Easy to rapidly develop a large alum, sedimentation good performance. Suitable for a wide range of PH value (5-9 rooms), and the treated water, PH value and alkalinity of a small decline. Water temperature is low, so as to maintain a stable sedimentation effect. Basicity than the other aluminum, ferric high, a small erosion of equipment.
3, physical and chemical index:
The product is a kind of inorganic polymer coagulant. Mainly through the compression layer, adsorption-charge neutralization, adsorption and bridges, such as sediment catch mechanism of the role of networks, so that fine particulates and colloidal ion edema off steady, aggregation, flocculation, coagulation, sedimentation, purification treatment effect.
4, use the method:
The product (solid) and room temperature water by 1 / 3 of the weight ratio while stirring dosing to completely dissolved, together with the water needed to dilute the concentration of the raw water concentration of 100 ~ 500mg / when the dosage is 3 ~ 6mg / I. Specific dosing should be based on water quality for water test, select the best dosage and then put into use.
5, packaging and storage:
Solid as a 25kg bag, inner plastic film, outer plastic woven bags, the product should be stored indoors, dry, ventilated, cool place, only once damp.
Spray Drying of Poly aluminum chloride
Product Name:
Spray Drying of Poly aluminum chloride, white poly aluminum chloride, molecular formula: [AL2 (OH) LnCL6-n] m technology standard: GB15892-2003
Features:
Spray-drying-type PAC, spray characteristics depend on the operation principle of the pressure. The pressure of spray-drying process produced a small aluminum chloride as the porous hollow particles or small particles, showing dust and smoothness. As the body of water to be processed with the contact better, its rate of wettable and water are stronger than the other powder products. Spray drying PAC production is not only, but at the same time to make them tiny particles. PAC for the water-soluble material and at the same time showed good thermal stability and solubility. Will be 40-50% of the aluminum chloride solution of inhaled high-pressure pumps, spray dried granular product.
In this production process, dehydration and the formation of particles at the same time.
Uses:
PAC is a kind of inorganic polymer flocculants. Hydroxyl ions through the multivalent anionic functional groups and the role of polymer functional groups, resulting in a with large molecular weight and high charge of the inorganic polymer. PH value can be adapted to the range of 5.0-9.0, the best PH value is 6.5-7.6.
1. Can be applied to rivers, lakes and groundwater treatment
2. Can be applied to industrial water treatment and industrial water recycling
3. Can be applied to wastewater treatment
4. Can be applied to coal washing waste water and industrial wastewater recycling porcelain.
5. Can be used in printers, dye houses, tanneries, breweries, meat processing plants, pharmaceutical plants, paper mills, coal washing, metallurgy, mining, as well as fluoride, oil, heavy metals in wastewater treatment.
6. Can be applied to leather and fabric wrinkle-free.
7. Can be applied to cement solidification and casting mold system.
8. Can be applied to pharmaceuticals, glycerine and sugar refining
9. Can be used as a good catalyst.
10. Can be applied to the adhesive paper.
PAC-01 (white powder, spray-dried): for drinking water, paper, pharmaceutical, cosmetic aids.
Specification: Al2O3 ,29-30%; basicity, 40-60; Water insoluble, less than 0.3%
PAC-02 (yellow powder, spray drying): for drinking water treatment and wastewater treatment.
Specification: Al2O3 ,29-32%; basicity ,70-85; Water insoluble, less than 0.5%
PAC-03 (yellow powder, roller dried): for drinking water treatment, industrial wastewater and municipal wastewater treatment.
Specification: Al2O3 ,29-30%; basicity ,80-95; Water insoluble, less than 1.5%
Application Method:
Users can according to different quality and different terrain, through pilot deployment of pharmaceutical concentrations, to determine the best dosage.
1. Liquid products can be directly put in, but also diluted running. Dissolved in diluted solid products need to run. Depending on the number of products to be processed to determine the water quality and water dilution. The dilution ratio of solid-state products 2-20%, liquid product is 5-50% (by weight).
2. Liquid products, put volume 3-40 g / t, solid running volume 1-15 g / t, specific in order to put the amount of flocculation tests and experiments shall prevail.
3. Spray-drying-type PAC acidity than other inorganic flocculants.
Spray-drying-type PAC PAC production process with common difference:
Spray Drying:
Pressure filter liquid raw materials ---- ---- ---- Finished spray tower spray drying
Common Drying:
Liquid raw materials to place ---- ---- ---- Finished drum drying
Synthesis of the different costs:
Spray drying products with high stability, to adapt to the waters wide, hydrolysis speed, strong absorption, flocculation to form quick and large, low turbidity, and the dehydration of super. For the same water, the spray-dried products put a small amount compared to other products, especially for high-pollution water quality, spray-dried product requires only half the amount of drum dried products can be not only reduced the labor intensity, but also reduce the customer's costs. In addition, spray-dried product launch will not cause too much pollution, avoid accidents, ensure the safety of drinking water quality.
