10/8/2000, · Wastewater containing acetic acid was introduced to the DSC. When an electric field is imposed, the A~ ions are transported from the DSC to the CSC through the anion-exchange membrane. Hydroxyl ions generated by a bipolar membrane are transferred to the DSC which then neutralize the hydrogen ions remaining after Ac removal.

22/10/2019, · A ,definition, of ,alkalinity, would then be "the buffering capacity of a water body; a measure of the ability of the water body to neutralize acids and bases and thus maintain a fairly stable pH level". In more simple terms, water with a high ,alkalinity, will experience less of a change in its own acidity, for instance, when acidic water, such as ,acid, rain or a ,acid, spill, is introduced into the water body.
