Is Huaian tap water weak acid, acidic or alkaline? What is its ph value? Do you need a water purifier to purify it?

The pH can be measured by an acid meter, because different water supply methods will have different water quality in a water plant in the same city.

The water in waterworks generally meets the drinking water standard when leaving the factory, but it generally contains residual chlorine, and secondary pollution may also occur. It is suggested that a suitable water purifier can be used if conditions permit.

Tap water has high hardness, so you can choose a water softener; The content of colloid and organic matter in tap water is high, so activated carbon water purifier can be used; Pre-filtration is necessary when there are a lot of sediments in tap water or when water is stopped from time to time. Anti-or water purifier is selected for serious pollution.
