The use of regeneration profiles as a tool to optimise the performance of demineralisation water treatment plants

Abstract

Demineralised water is used as make-up water to compensate for losses in the condensate-boiler feed-water stream at power stations and other steam raising plants. Demineralisation plants are designed to produce pure water that contains virtually no impurities. Ion exchange is invariably used for demineralisation. Effective regeneration of exhausted resin is an important aspect to ensure optimal performance of the ion exchange process. Regeneration profiles were used in this investigation to determine the effectiveness of regeneration and to optimise the regeneration process.
