Veolia Water Technologies & Solutions

E-Cell* Electrodeionization (EDI) Systems

Standardized systems for complete EDI solutions

E-Cell EDI systems are pre-engineered and readily available with 1 - 12 E-Cell MK-5 EDI Stacks or 16-20 E-Cell MK-9 EDI Stacks. Drawing on extensive EDI expertise and proven engineering practices, these systems represent years of refinement in design and construction. E-Cell EDI systems offer streamlined project implementation for both EDI newcomers and those seeking to benefit from Veolia's manufacturing excellence.

Overview

While built upon four foundational designs, E-Cell EDI systems offer customizable configurations by adjusting stack quantities to match specific capacity requirements. Flow rates can be fine-tuned for each stack to achieve desired water quality parameters, as calculated through Winflows EDI projection software. Detailed specifications for individual stacks are available on the E-Cell Electrodeionization (EDI) Stacks page.


All systems offer flexibility for enhancement by upgrading from E-Cell MK-5 EDI stacks to E-Cell MK-9 EDI stacks, enabling a substantial 60% increase in nominal flow capacity.
