Abstract:
1. A method of preparing a first cell stack for an electrical purification apparatus comprising: securing a first anion exchange membrane to a first cation exchange membrane at a first portion of a periphery of the first anion exchange membrane and the first cation exchange membrane to form a first compartment having a first fluid flow path; and securing a second anion exchange membrane to the first cation exchange membrane at a second portion of the periphery of the first cation exchange membrane and a first portion of a periphery of the second anion exchange membrane to form a second compartment having a second fluid flow path in a direction different from the first fluid flow path, each of the first compartment and the second compartment constructed and arranged to provide a fluid contact of greater than 85% of the surface area of each of the first cation exchange membrane, the first anion exchange membrane and a second cation exchange membrane.
