Polyaluminum chloride has industrial grade and drinking water grade. In some places where drinking water is scarce, drinking water grade polyaluminum chloride will be used to treat some groundwater or rainwater, but can the treated water be drunk directly? Will it do great harm to human body? Let's talk about it briefly today.

Drinking water grade polyaluminium chloride is widely used in waterworks. However, after using drinking water grade polyaluminium chloride in waterworks, many steps need to be taken to deal with it, such as filtration, sedimentation, disinfection, sterilization and so on, before people can use drinking water normally. The standard of drinking water grade polyaluminum chloride used in waterworks is higher, and the treatment process of drinking water is also very fine, so that people can drink safely.

However, groundwater or rainwater treated with drinking water grade polyaluminum chloride can not be directly drunk. Groundwater and rainwater generally have low turbidity, which can be well removed after treatment with polyaluminum chloride, so it looks no different from ordinary drinking water, but some harmful and toxic substances can not be seen by people's eyes. These toxic substances generally contain some harmful substances in the original water quality. The residual chlorine and aluminum ions after treatment with polyaluminum chloride will cause certain harm to human body, and these substances generally cannot be removed after precipitation and high temperature. Therefore, only the groundwater and rainwater after treatment with polyaluminum chloride can not be directly drunk.

The water treated by polyaluminum chloride must go through the corresponding treatment process in order to meet the standard of drinking water.
