What does multi-stage filtration mean in practice?
The sequence of stages is arranged so that the earlier stage protects the next, for example, sedimentation before carbon and carbon before the RO membrane.
When does it matter?
Duplicating similar cartridges does not automatically increase effectiveness and may unnecessarily lower pressure and increase service costs.
Which solutions are related to it?
Each stage is assigned a specific purpose, scope of work and criterion for replacement, cleaning or regeneration.
