This product shows the flowing features compared with other coagulants:
1. Wide application, and adapt to most kind of water.
2. Easy to quickly shape big alum fume, and showing good setting behavior.
3. Adapt to wide PH value ( 5-9), and the PH value and alkalinity of water after treatment decrease little.
4. Keeping good precipitating effect even at low temperature.
5. Alkalization degree is higher than other aluminium and iron salts, and have little erosion effect to equipments.

Uses:
In order to get optimum flocculation effect and lowest cost, you can determine the optimum input through tests according to different raw water turbidity, change of seasons, and the shapes of pond. Liquid products should be mixed to be 5-10% aqueous solution, and solid products should be mixed to be 3-5% aqueous solution. More higher is the turbidity of the raw water, more thinly is the solution mixed, and you can improve the product input and get better flocculation effect.
