Abstract
PURPOSE: To concentrate organics as well as remove inorganics present in waste water by bringing pulp mill waste water into contact with a amphoteric ion-exchange membrane under pressure.
CONSTITUTION: Waste water discharged from pulping process is brought into contact with an amphoteric ion-exchange membrane with both a cation exchange group and an anion exchange group while being pressurized in order to concentrate organics and also to separate inorganics, using an apparatus selected from the well- known pressurized concentrators used in reverse osmosis method or ultrafiltration method according to the shapes of membrane, e.g., flat membrane, tubular membrane, etc. The operating pressure, although different according to the properties of pulp mill waste water to be treated, is usually within the range of 10W150kg/cm2 and also the temperature at the time of operation is preferably at 20W80°C.
