Abstract
The cost, and its breakdown into components, of an ion exchange process for desalination and waste water recycling is presented. Using the effect of the 1973-1974 jump in the price of energy on the cost of treatment, the expected future trend is calculated. It was found that the net energy component in ion exchange water treatment is 14.5% when lime is used for regeneration, and 17% when NaOH is used. The substitution of lime for NaOH reduces the treatment cost and makes the ion exchange process an economical method for desalination and waste water recycling. "Non-conventional" approaches such as a continuous fixed-bed process, a system including recycling of regenerants, regeneration thermally or with waste acids are also discussed.
