Selection of the Best Process Stream to Remove Ca²⁺ Ion Using Electrodialysis from Sugar Solution

Figure 11

Comparison of Ca²⁺ ions (feed solution, 25 mol·m⁻³) removal rate between two different techniques adopted. Case 1: anolyte = 100 mol·m⁻³ HCl; catholyte = 100 mol·m⁻³ NaOH. Case 2: anolyte = 100 mol·m⁻³ HCl; catholyte = 25 mol·m⁻³ Na₂EDTA + 25 mol·m⁻³ AA [13].
