Performance: normal precipitation contains 18 molecules of water of crystallization, aluminum sulfate 18 water, 18 water production, mostly aluminum sulfate industry. Anhydrous aluminum sulfate containing 51.3 percent, even 100 degrees Celsius is not autolysis (self crystals were dissolved in water). Lose crystal water easily weathered, more stable, heating water loss, high temperature will decompose alumina, and sulfur oxides.
1.Its purifying effect on low-temperature, low-turbidity and heavily organic-polluted raw water is much better than other organic flocculant, furthermore, the treatment cost is lowered by 20%-80%.
2.It can lead to quick formation of folc (epecially at low temperature) with big size and rapid precipitation service life of cellular filter of sedimentation basin.
3.The dosage is smaller than that of other flocculants, which is better for improving the quality of treated water.
4.It has widerange adaptability to the waters at different temperatures (in the summer and the winter) and at different regions (in the south and the north of China).
5.It is suitable for automatic dosing device of alum.
6.It can adapt to a wide range of pH value (5−9), and can reduce the pH value and basicity after processing.
