Polyaluminum chloride is widely used in water purification and has a good effect, but sometimes it will affect the use effect of polyaluminum chloride due to improper use methods. Today, we will explain several correct methods of using polyaluminum chloride:
1. According to different purified water quality, selecting polyaluminum chloride water purifying agent that is more suitable for purifying water quality can not only greatly reduce its use cost, but also significantly improve the use effect of polyaluminum chloride purification treatment.
2. Select the appropriate coagulant type and dosage according to the different types of wastewater to be treated. The type of polyaluminum chloride is wrong, and it cannot achieve the expected purification effect in purified water. The consumption of polyaluminum chloride is too small to achieve the expected purification effect of the product. Excessive consumption will cause waste of products.
3. Ambient temperature when using polyaluminum chloride. We know that different chemical reactions have different effects at different temperatures. Pay attention to different temperatures of water when using polyaluminum chloride. Different water purification materials should be selected according to different water temperatures. For example, when the water temperature is low, the effect of activating silicic acid with anionic inorganic polymer electrolyte is very good.
Therefore, in the process of purification treatment with polyaluminum chloride, we should be able to select more suitable water purification materials according to the different water quality and temperature of the wastewater to be treated, so as to purify the wastewater to the level of clean water quickly and economically.
