Regular Replacement for Optimal Performance
To guarantee optimal performance of electrodialysis stacks, its necessary to care about regular replacement. The exact annual replacement rate depends on how extensively your technology is used. For the common use in dairy industry, these are the supposed replacement rates: ED membranes - 25% a year (usual life-time of 4 years). ED spacers - 10% a year (usual life-time of 10 years). ED membranes - 66% a year (usual life-time of 1.5 years).
