Products manufactured through spray drying process show features of high stability, adaptation to wide water area, quick hydrolysis speed, strong absorptivity, big flocs, quick precipitation, low turbidity out of water and superior dehydration property. Spray drying products are needed less than other products for the treatment of same water quality, and especially for seriously polluted water, Spray drying products are only needed half less than roller drying products, which can not only decrease worker’s labor intensity, but also reduce clients’ water cost. Besides, spray drying products can avoid water accident, and are more safe and reliable for drinking water.

This product possess the following advantages compared with other coagulants:
1. Wider application, better water adaption.
2. Quickly shaping big alum bubble, and having good precipitation.
3. Better adaption to PH value (5-9), and little declining range of PH value and alkalinity of water after treatment.
4. Keeping stable precipitation effect at lower water temperature.
5. Higher alkalization than other aluminium salt and iron salt, and little erosion to equipments.
