This product is widely applicable to urban sewage treatment and various industrial sewage and wastewater treatments, such as printing and dyeing wastewater, leather wastewater, fluorine-containing wastewater, heavy metal wastewater, oil-containing wastewater, papermaking wastewater, coal washing wastewater, mining wastewater, brewing wastewater, metallurgical wastewater, and meat processing wastewater. Additionally, it can be used for the recovery of useful substances from industrial wastewater and waste residues, promoting the sedimentation of coal powder in coal washing wastewater, and the recovery of starch in the starch manufacturing industry. It is used for domestic drinking water treatment, and especially has a better treatment effect on low-temperature, low-turbidity, and alkaline water. Usage of liquid polyaluminum chloride The liquid polyaluminum chloride product is already dissolved, so when using it, directly add an appropriate amount of the product to the water to be treated, and stir vigorously to mix it evenly with the water. The dosage varies depending on the water to be treated. Generally, the dosage for water purification is 5-100 grams per ton for liquid products, which can be determined through beaker tests. It can be directly added to water when preparing; the amount of water added can be determined according to the dosage and the amount of water to be treated, and it should be stirred evenly after adding water. The specific dosage depends on the raw water; a coagulation test in a beaker should be conducted to determine the optimal dosage. This product should be kept away from moisture, but it can still be used after getting damp, and its efficacy remains unchanged.

·The flocculant forms quickly, with good activity and filterability. ·No alkaline additives are needed. Even if it deliquesces, its effect remains unchanged. ·It is suitable for a wide pH range, has strong adaptability and a wide range of uses. ·There is less salt in the treated water. ·It can remove the pollution of heavy metals and radioactive substances to water.
