METHODS OF REMOVING CHLORIDE FROM WASTE WATER OF FERTILIZER PRODUCTION

摘要

The present invention relates to treatment of industrial wastewater, and more particularly wastewater from a fertilizer plant such as a nitrophosphate, other mineral or organo‐mineral fertilizer plant. Chloride ion can be removed by electrolysis and in more particular aspects of the invention, the electrolysis is made more efficient by increasing mass transport within the electrochemical cell. One particularly effective method of increasing the mass transport is to use electrolyte jets. By reducing the chloride concentration in the fertilizer wastewater, it is then possible to safely recirculate the wastewater back to the fertilizer plant.
