Basic aluminum chloride in the printing and dyeing mill sewage treatment Gongyi City, filter source water purification materials plant production of dyeing and printing wastewater treatment with basic aluminum chloride. Alkali aluminum chloride is the late 60s, officially put into industrial production and application of a new type of inorganic polymer coagulant. Is the use of industrial aluminum ash and activated bauxite as raw material after polymerization polymerization, the higher activity of this product for industrial wastewater, paper water, printing and dyeing water has a better purification effect. With less dosage. Purification efficiency. Low cost and a series of advantages. National GB15892-2003 standard basic aluminum chloride Features: 1, floc forming fast, good activity, good filtering. 2, without adding alkaline additives, such as case of deliquescence, its effect unchanged. 3, to adapt to PH wide, strong adaptability, wide range of uses. 4, less salt water treatment. 5, to remove heavy metals and radioactive substances on the water pollution. 6, the active ingredient is high, easy to store, transport. Alkali aluminum chloride Purification agent Alkaline aluminum chloride can sterilization, deodorization, decolorization, in addition to fluoride, aluminum, chromium, phenol, degreasing, turbidity, in addition to heavy metal salts, in addition to radioactive contaminants, Water has a wide range of uses. Example: Purification of domestic water, domestic sewage. Purification of industrial water, industrial waste water, mining, oilfield water injection, purification of paper, metallurgy, coal washing, leather and various chemical waste water treatment. Industrial production applications: paper sizing, dyeing and printing and dyeing, cement quick-setting agent, precision casting hardening agent, refractory adhesives, glycerin refining, sugar refining, anti-wrinkle cloth, medicine, cosmetics and other industries, the wastewater can be recycled. In the oil refining industry, for oil and water separation, the effect is very good. Basic aluminum chloride Note on the use and dosage ⒈ according to the different conditions of raw water, before use, try to get the best dose. For ease of calculation, small test solution configuration by weight (W / W), usually 2 ~ 5% with good. If equipped with 3% solution: said polyaluminum chloride solid 3g, into a clean 200ml measuring cylinder, add about 50ml of water, to be dissolved and diluted with water to 100ml scale, shake well. ⒉ production by polyaluminum chloride solid: water = 1: 9 to 1:15 weight ratio (liquid products using 1: 2 to 1: 5) can be mixed and dissolved. Alumina content of less than 1% of the solution is easy to hydrolysis, will reduce the use of effect, the concentration is too high not easy to vote evenly. ⒊ dosing by small test obtained the best dosage dosing, and observe the operation of the adjustment.
