Calcium hydroxide is widely used in production and life. Can use slaked lime and sand mixed brick, lime stucco; lime painted on the trees containing sulfur powder, etc., can protect trees, prevent frostbite, and prevent insect eggs; preparation of concrete; agriculture with lime milk and copper sulfate solution prepared with the bactericidal effect of Bordeaux mixture as pesticides. To change the acidity and alkalinity of the soil will be the right amount of lime into the soil, can neutralize the acidity, change the acidity and alkalinity of the soil, easy crop survival. Food additive sodium hydroxide, bleaching powder.
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.
