Description

The mechanism for variable sorption capacity of
boron on ion exchange resins in multicomponent
systems was established. The model was derived from
fundamental continuity equations and uses
correlations and constants to estimate system
properties and parameters as a function of time and
bed depth. Implementation of solution thermodynamics
for boron into the rate model was completed
successfully. The decision of optimal time and
distance increments is essential because of errors
incoporated with numeric integration. The time and
distance increments between 0.005 and 0.01 are
recommended for most cases for proper run time and
small total material balance errors. The model obeys
the acceptable and required trends at wide operating
conditions with increased complexity of the water
chemistry. As the complexity of water chemistry
increaesd, the run time and total material balance
errors increased.
