First, the nature of the product   PAC (basic aluminum chloride) referred to PAC or BAC, is a new high polymer flocculant. It is a product between the AlCl3 and Al (OH), its main features are: 1 floc forming fast, good activity, good filtration. 2 without adding alkaline additives. In case of deliquescence effect unchanged. 3. Adapt to a wide PH value for waters wide, wide range of uses. 4 salt water treated less. 5 can remove heavy metals and radioactive substances to water pollution. Second, the product uses   can sterilization, deodorization, bleaching, fluoride, aluminum, chromium, phenol, oil, turbidity, except heavy metal salts, with the exception of radioactive contaminants in water purification with a wide variety of uses, such as : a purifying drinking water, sewage. 2 industrial water purification, industrial wastewater, mining, oil field injection water, purify papermaking, metallurgy, coal washing, leather and various chemical industrial waste water and so on. 3 industrial applications: paper sizing, printing dyeing, quick-setting cement, hardened precision casting, etc., can be used for recycling refractory bonding, glycerine refining, sugar refining, wrinkle-free fabric, pharmaceutical and cosmetics industries and wastewater utilization. 4 In the oil refining industry, for oil-water separation. Third, the physical and chemical indicators Analysis Project Analysis Project Index Index alumina (Al2O3)% 29-31 arsenic (As) content% <0.0005 Basicity 60-85% manganese (Mn) content of 0.01-0.05% 0.5% Water-insoluble matter 1.5 Mercury (Hg) Content% <0.00002 PH value (1% solution) 3.5-5.0 lead (Pb) content% <0.003 ammonia nitrogen (N)% <0.05 Cadmium (Cd) content% <0.0005 Fourth, use: PAC dosage (solid) by weight in water at room temperature with 1/3 ratio of the dosage stirring until completely dissolved, then diluted with water to the desired concentration, the concentration of the raw water 100 ~ 500mg / time is 3 ~ 6mg / I. When specific dosing, the test should be carried out according to the water quality of the water, and then select the best dosage is put into use. Packing and Storage: Solid as a 25kg bag, inner plastic film, outer plastic bags, aluminum chloride should be stored indoors in a dry, ventilated, cool place, and do not get wet. Product Name: Spray drying PAC, white PAC, MF: [AL2 (OH) LnCL6-n] m Technical Standard: GB15892-2003 Product Features: spray drying PAC features depends on the pressure sprays Operating Principles. The pressure produced by the spray drying process the aluminum chloride as small particles or porous hollow small particles, dust and exhibit smoothness. Due to the water to be treated better contact its wettability and water velocity are stronger than other powdered products. Spray drying is not only the production of PAC, but at the same time make it into tiny particles. PAC is a water-soluble substance while exhibiting good thermal stability and solubility. 40-50% aluminum chloride solution into the high pressure pump, spray dried granular product is formed. Simultaneous dehydration and particle formation in this production process. Usage: PAC is an inorganic polymer flocculant. Hydroxyl ions through the polyvalent anionic functional groups and functional groups of the polymerization, resulting in a large molecular weight and has a high charge inorganic polymer. Can be adapted to the range of 5.0-9.0 PH value, the best PH value 6.5-7.6. 1 can be used in rivers, lakes and groundwater treatment 2 can be used in industrial water treatment and industrial water recycling 3 can be used in wastewater processing 4. scouring wastewater can be used in coal mines and porcelain industrial wastewater recycling. 5 can be used in printing, dyeing, tanneries, breweries, meat processing plants, pharmaceutical plants, paper mills, coal, metallurgy, mining, as well as fluorine, oil and heavy metals in waste water treatment. 6 can be used in wrinkle leather and fabric. 7 can be used in cement solidification and mold casting. 8 can be used in pharmaceuticals, glycerine and sugar refining 9 can be used as a good catalyst. 10. Adhesive can be used in papermaking. PAC-01 (white powder, spray drying): for drinking water, paper, pharmaceutical, cosmetic aids. Specification: Al2O3 ,29-30%; Basicity 40-60; water insoluble, less than 0.3% PAC-02 (light yellow powder, spray dried): for drinking water treatment and wastewater treatment. Specification: Al2O3 ,29-32%; basicity ,70-85; water insoluble, less than 0.5% PAC-03 (yellow powder, drum drying): for drinking water treatment, industrial wastewater and municipal wastewater treatment . Specification: Al2O3 ,29-30%; basicity ,80-95; Water insoluble, less than 1.5% Applications: Users can according to different quality and different terrain, through the deployment of agent concentration tests to determine the best dosage. 1. Liquid product can be directly put in, it can be diluted after launch. After dilution needed to dissolve the solid product launch. According to the water quality and quantity of products to be processed to determine the dilution water. The dilution ratio of 2 to 20% solid products, liquid products (the weight) 5-50%. 2 PAC put the amount of liquid is 3-40 g / t, put the amount of solid 1-15 g / t, the specific amount invested in the flocculation tests and experiments prevail. 3 spray drying PAC acidity than other inorganic flocculants. The difference with ordinary spray drying PAC PAC production process: spray drying: liquid materials ---- pressure filter ---- spray tower spray drying ---- Finished ordinary Drying: Liquid raw materials - - Place ---- drum drying ---- Finished
