RINSEBED
The Rinsebed system is suitable for small to medium-sized units with a diameter of up to 2000 mm. The units have a collector system just above the mid-point. The treated water is removed through this system. Immediately above the collector system is a perforated plate. The holes in this plate should be large enough to allow the resin beads to pass through it.

The holes in this plate should be large enough to allow the resin beads to pass through it.
The column is filled until the resin covers the perforated plate which divides the unit into a lower, active chamber and a so-called top layer (200-350 mm). After backwashing, the finest beads return to the top layer which adsorbs certain ions during rinsing or if the regenerant is diluted with raw water.
This resin layer is responsible for producing the high-quality water required for rinsing and dilution.
Advantages of the Rinsebed process:
- internal backwashing
- raw water can be used for regeneration or to rinse cation resins
- decationised water can be used for regeneration or to rinse anion resins
- suitable for small, single units
