2．High purity PAC:
　According to GB15892-1995, Fe2+ ≤200ppm , SO42﹣≤100ppm
　Configuration speciality and the mechanism of blending agglomeration
　PAC is composed of a series of inorganic macromolecule compound which has different polymerization degree, and has the best shape distributing. It mainly distributed into Al13O4(OH)24(H2O)24(H2O)127+.
　It has the Keggin configuration and high electricity polymeric annular chain shape, and has the high electricity neutralization and bridging function to the colloid and grain substance in water. It has the strong power of removing the poisonous matter and heavy metal ion.
　The neutralization with the colloid and grain substance in water makes colloid unstable, and the colloid and grain substance agglomerate quickly. With the bridging function as the agglomeration becomes bigger and bigger, and it will sedimentate quicker eventually.Speciality of blending agglomeration
　1. PAC is a kind of inorganic macromolecule agglomeration agent. Through the hydroxyl ion bridging function and the polyvalent anion polymeric function, it produces large molecule and higher electricity inorganic macromolecule.
　2. The purified water quality is better than the water treated by aluminium sulphate, and the cost is lower than any of other inorganic blending agglomeration agents.
　3. Quick agglomerating and sedimentating, and the treatment ability is stronger than aluminium sulphate or any other traditional products.
　4. The alkali consumption in water is lower than any other kind of inorganic blending agglomeration agents, and alkali may not be necessary.
　5. It adapts a wide PH range of 5.0 to 9.0 and the best PH is between 6.5 and 7.5.
　6. Less erosive and easy to use.
　7. Better dissolubility than aluminium sulphate.
　8. Adding little salt content in treated water, and this is favorable for ion to exchange.
　9. It adapts a wider range of temperature than aluminium sulphate and any other inorganic agglomeration agents.Purpose
　1. Purification of river water, lake water and underground water in city water supply.
　2. Purification of industry water and industry circulation water.
　3. Purification of city polluted water.
　4. Recycling coal from the coal-washing polluted water, and recycling kaolin in ceramic industry.
　5. Purification of the polluted water in printing and dyeing industry, leather industry, brewage industry, meat-processing industry, coal-washing industry, metallurgy industry, mine industry, pharmacy industry and paper-making industry etc. and the purification of the polluted water containing fluorine, oil and heavy metal.
　6. Wrinkle-free from tan and cloth.
　7. Solidifying cement quickly, founding and moulding.
　8. As the cosmetic material.
　9. Curative refining, glycerine refining and liquid sugar refining.
　10. Catalyzer carrier.
　11. Paper-making glue.Usage and attention
　To achieve the best agglomeration effect and the lowest cost, before using the product, the best dosage should be defined, and then put into industry debugging.
　1. To improve the dosage definition, it should be dissolved and diluted before use. According to the treating-water to define the solution consistence. In general, the solution consistence should be 1-5 percent of the product.
　2. The ideal dosage should be defined according to the treating-water character and the output water requirement. In general, the dosage is suggested from the following form:
River water (ppm) Industry circulation water(ppm) Industry polluted water (ppm) Life polluted water (ppm) Paper making glue (%)
Drought period Flood period
Dosage 5--10 20--100 10--50 200--500 50--200 2-3
　3.Other water-treating agent made from different manufacturers should not be mixed with each other, and should never mixed with other chemicals.
　4.Solid product should be kept in dry condition, and should be used immediately when it opened, even though it doesn effect the performance in moisture.
　5.Liquid product and its dilute solution are a little corrosive, and anticorrosive container should be used.
　6.The liquid product can be kept for one year and solid product for two years.Technical and service support
　1.We have professional engineering technical team who can provide on-site and after-sale service, and help our customers to get the best treatment effect.
　2.We provide the complete technology, include the evaluation of treating project, feasibility report, project design construction and installation adjustment.
　3.Conducting on-site experiment for customers to observe the treatment effect. Directing the debugging of the water treating equipment and the reasonable selection of medicament. Providing the cost analyzing report for customers.
