Produced from modified aluminum salt raw materials and added with low-temperature activity accelerators, it significantly improves the dissolution speed and flocculation performance in low-temperature water at 5-10℃. Compared with conventional polyaluminium chloride, the flocculation efficiency in low-temperature environment is increased by more than 40%. The product has fine powder and fast dissolution speed, which can disperse quickly even in low-temperature water. At the same time, it has strong anti-pollution ability, which can effectively remove refractory organic matter such as humic acid and fulvic acid in low-temperature water, avoiding the formation of disinfection by-products in low-temperature water.
The aluminum oxide content is ≥29%, the pH value of 1% aqueous solution ranges from 4.0 to 5.5, the moisture content is ≤6%, the particle size is 0.1-0.3mm, the dissolution rate in cold water at 5℃ is ≥95%, the solubility is ≥99%, the heavy metal content meets the national GB standard, the packaging specification is 25kg/PE-lined carton, it needs to be stored in a cool and dry environment, with a shelf life of 2 years. It is suitable for raw water treatment scenarios with a water temperature of 5-10℃ and has no special storage requirements.
It is mainly used in winter tap water plants, small water purification stations, river ecological restoration projects and other scenarios in northern China. It can treat low-temperature and low-turbidity surface water and groundwater, solving the problems of low water treatment efficiency and substandard effluent water quality in winter. It can also be used in drinking water purification projects in alpine regions, providing a reliable flocculant solution for winter water source purification.
