Concentration Quantities and Unit Conversions - EWT Water

May 05, 2018 · In natural waters, the buffer capacity is mainly related to the equilibrium of calcium carbonate and carbonic acid, and is denoted by the m-alkalinity or total alkalinity in regards to acids, and the p-acidity in regards to bases. The dissociation constant for the self-ionisation of water increases with increasing water temperature.

Understanding Ultrapure Water and the Difficulties with pH

The same objective (removal of some of the feedwater alkalinity and CO2) can be reached by the use of a degasifier. The degasifier can be located ahead of the first RO machine or between the two passes. Should some alkalinity pass into the RO permeate, it will re-equilibrate, forming H2CO3, HCO3 and/or CO3-2 in proportion to the pH.
