Polyaluminum chloride is divided into spray drying and drum drying Poly aluminum chloride pac drying there are two ways, one is spray drying, one is drum drying, then the spray-dried polyaluminum chloride should be how to use 1. Spray dry PAC prior to use. Poly aluminum chloride according to a certain concentration (10-30%) into the solvent pool, into the tap water and stir to make it fully hydrolyzed and allowed to stand until the reddish brown liquid , Then 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 polyaluminium chloride pac 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 Under this product and the amount of solid polymeric alumina slightly lower, the amount of solid aluminum sulfate 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 PAC paclitaxel under normal circumstances the day of preparation, pharmaceutical needs tap water, a slight precipitate is a normal phenomenon. 5, spray-dried PAC polled attention to the three stages of the coagulation process of hydraulic conditions and the formation of alum situation. 6, spray-dried polyaluminium chloride pac enhanced filtration, mainly the rational use of filter layer structure and filter aid to improve the removal rate of high filter, it is an important measure to improve water quality. 7, spray-dried PAC PAC This product is used in environmental protection, industrial wastewater treatment, the use of the same with the water plant, the high color, high COD, BOD, raw water treatment, supplemented by additives The effect is very good. 8, spray-dried PAC PAC chemical coagulation plant, the original equipment without making a major transformation, just add a solvent pool can use the product. 9, spray dry PAC PAC This product should be stored in a dry, moisture-proof, heat (<80 ℃), do not damage the packaging, the product can be stored for a long time.
