Nomenclature

Cl2(s)

Soluble chlorine from chlorine hydrolysis (in g dm−3) following Cl2+H2O→HCl+HOCl, (calculable from the correlations in [3])

Cspecies(a)

Concentration of species noted in the subscript in the anolyte (g dm−3)

Cspecies(d)

Concentration of species noted in the subscript in the depleted brine (g dm−3)

Cspecies(f)

Concentration of species noted in the subscript in the feed brine (g dm−3)

F

Faraday constant (96.487 kAs mol−1)

I

llad (kA)

q

depleted brine flow rate (dm3 s−1)

p

feed brine flow rate (dm3 s−1)

CNaClO3(d)

NaClO3 in depleted brine (g dm−3)

CNaClO3(f)

NaClO3 in feed brine (g dm−3)

Cl2(d)

total dissolved chlorine in anolyte (gdm−3)
