America. In other parts of the world some mills express the concentration in terms of sodium hydroxide (NaOH). It is always good to check whether the basis is Na2O or NaOH when talking to mills outside North America. The amount of AA required per day will determine the flow of white liquor required from the recausticizing plant.
