Comparison of desalination performance between our units built at the Technical University of Liberec (TUL) and the results reported by [20] (marked as Reference units) at the same dimensionless current, a parameter defined by Equation (1). The number presented in the reference unit column expresses the desalination performance of Schlumpberger’s reference unit at the same dimensionless current as was used to characterize the Gen. II and III units, respectively. The “Gen. II unit” used silica glass frit and a design very similar to the reference unit, and the “Gen. III unit” was a scaled-up unit described above, fitted with silica ceramics with the porosity and pore size comparable to the glass frit.

	Desalination (%)
Dimensionless Current (1.1.)	Gen. II Unit	Gen III Unit	Reference Unit
Ĩ ≈ 0.4	36	-	≈ 40
Ĩ ≈ 0.6	-	40	≈ 60
