Some plants have waste-waters from air pollution control devices for painting operations. These residues are treated in a manner similar to free oils. Normally, the wastes are slightly acid or alkaline, and they are usually opaque, milk-coloured, and contain some free (non-soluble) oil.

Is Your Water Acidic or Alkaline? The Impact of pH on Water
Is Your Water Acidic or Alkaline? The Impact of pH on Water

For example, if RO water is exposed to air, carbon dioxide will dissolve into water, causing it to become ,acidic,. That said, reverse osmosis water contains almost no traces of dissolved solids, making it a more pure source of water. This type of water is so pure that even the smallest amount of acid or ,alkaline, can impact its pH level.
