The use of spray-type polyaluminium chloride The use of spray-type polyaluminium chloride
Poly aluminum chloride is dried in two ways, one is spray-dried, one is drum-dried, then spray-dried polyaluminum chloride How to use it 1. Spray dry PAC before use. Put PAC into the pool at a certain concentration (10-30%), mix with tap water to make it fully hydrolyzed and let stand until it is red Brown liquid, diluted with water to the desired concentration dosing coagulation. Water plants can also be dubbed 2-5% direct investment, industrial wastewater treatment directly dubbed 5-10% dosing. 2, spray-dried polyaluminum chloride dosage to determine, according to the nature of the raw water through the production of debugging or burnout experiment as alum to form the appropriate amount .Water plant can use other drug dose as a reference, under the same conditions This product is slightly lower dosage of solid polymeric alumina, solid aluminum sulfate is the amount of 1 / 3-1 / 4. If the original is a liquid product, according to the corresponding drug concentration calculation discretion. 3, the use of spray-dried polyaluminum chloride, the preparation of a good liquid medicine, pumped into the metering tank, dosing liquid by measuring the coagulation with raw water. 4, spray-dried PAC generally under the same day the day of preparation, dispensing need tap water, a slight precipitate is a normal phenomenon. 5, spray-dried polyaluminium chloride Note the three stages of the coagulation process of the hydraulic conditions and the formation of alum situation. 6, spray-dried polyaluminium chloride reinforced filter, the main reason is the rational use of filter structure and filter aid to improve the removal rate of high-filter, it is an important measure to improve water quality. 7, Spray-dried polyaluminum chloride This product is used in environmental protection, industrial wastewater treatment, use the same method and the water plant, the high color, high COD, BOD, raw water treatment, supplemented by the role of additives Very good. 8, spray-dried PAC are chemical coagulation plant, the original equipment without making a major transformation, just add a solvent pool can use this product. 9, spray-dried polyaluminum chloride This product should be stored in a dry, moisture-proof, heat-resistant (& lt; 80 ℃), do not damage the package, the product can be stored for a long time.
